According to NEC(National Electrical Code), there are three types of sections of a building’s inside area: plenums, risers and general purpose areas. As the higher and higher demands of the building network safety, types of fiber cables are not limited to the general types. Nowadays, some particular materials are used in the jackets of the fiber cables which can adapt to more applications, such as the sections above. Today, we are mainly taking about the plenums and its required cables in this paper while Fiberstore recently launched its new plenum(OFNP) fiber cables.
What is Plenum Space?
Plenum is an air-handling, air flowing and air distribution system space which is usually at greater than atmospheric pressure. In a building, plenum always refers to the space above a drop ceiling or under a raised floor which is used as the air return (source of air) for the air conditioning and typically used to wire the communication cables for the building’s computer and telephone network. However, the plenum is also a potential safety hazard. As the plenum spaces are full of fresh oxygen, fire can quickly spread into the plenum space. In addition, when cables were burning, they would give off toxic fumes and the fumes would be fed to the rest of the building by the air conditioner.
What is Plenum(OFNP) Fiber Cable & Why we need it?
Due to the potential safety hazard of the plenum spaces, people put forward many solutions. The plenum(OFNP) fiber cable is one of the achievements. OFNP stands for Optical Fiber Non-conductive Plenum. Plenum(OFNP) fiber cables is one of the highest levels which complies with the UL(Underwriters Laboratories) fire safety test. As we known, plastic cables burn quickly and give off toxic fumes and the black smoke. What is worse, they can spread the fire to the other parts of building once they catch fire. In order to protect the fires and keep more safety, any cables installed in a plenum space must be plenum rated. Because plenum cables are routed through air circulation spaces, which contain very few fire barriers by being coated in flame-retardant, low smoke materials.
How to Buy Plenum(OFNP) Fiber Cable with A Low Cost?
Although the NEC may allow non-plenum cable, Fire Marshall of many countries require their local building to use plenum cables in the network deployments of the plenum space. As the particular materials of the plenum(OFNP) fiber cable, cost of it may more expensive than the plastic one. It is not universally used in many developing countries. wanna a low cost safe cabling item of your plenum space, Fiberstore is your best choice!

The cost of plastic optical fibers (POF) in high-speed short-distance communication transmission is as same as symmetrical cables, the transmission bandwidth up to several GHz within 100 meters, and with easy connection, good flexibility, easy bending and other advantages. Despite the current system performance is still in the early stage of research or application, but it is not to be ignored of its roles in the future short distance communication, from the advantage of price and performance, making it has a broad prospect in the whole fiber optic network of FTTH application.
Compared with quartz fiber, POF has the following advantages: low modulus, large core diameter (0.3-1.0mm), can use simple POF connectors when splicing, even if the 30μm deviation produced by optical fiber splicing centre alignment does not affect the coupling loss; large numerical aperture (about NA0.5), the acceptance light angle up to 60°and that of quartz fiber is only 16 °, availability of cheap LED, and high coupling efficiency;flexibility is good, easy to manufacture and use; a low loss window in the range of visible light; light weight; low cost and processing cost.
Compared with other transmission mediums in the LAN(Local Area Network) system, POF network also has obvious advantages: POF is not sensitive to electromagnetic interference, no radiation, attenuation constant in different data rates, error rate can be forecasted, can be used in electrical noisy environment; features long-size, can reduce the requirement of tolerance control in joint design, so lower the cost of net.
Plastic optical fiber as the ideal transmission medium for short-distance communication network, plays an important role in the data transmission of future intelligent household, office automation, industrial control network, the airborne communication network, military communication network.
Through the plastic optical fiber, we can realize the networking of intelligent home appliances (home PC, HDTV, telephone, digital imaging equipment, security equipment, air conditioning, household refrigerators, sound system, kitchen appliances, etc.), getting home automation and remote control management, improving living quality. Through the plastic optical fiber, we also can realize the office equipment networking, for example, computer networking can realize the computer parallel processing, can greatly improve the working efficiency of high-speed data transmission between the office equipments, realizing telecommuting and so on.
When the data rate is less than 100Mbps of low speed LAN, SI plastic optical fiber can realize the transmission within 100 meters and small numerical aperture POF can achieve the transmission in 150Mbps50m.
At present, POF is also widely used in the manufacturing industry. Through the converter, POF can be connected with RS232 converter, RS422 converter, 100Mbps Ethernet, token ring and other standard protocol interfaces, thus providing stable, reliable communication lines in harsh industrial manufacturing environments. POF enables high-speed transmission of industrial control signals and instructions, avoiding the risk of communication interrupt resulted by electromagnetic interference with metal cable lines.
POF is lightweight and durable, can form a network of on-board unit communication network and control system, the micro-computer, satellite navigation devices, mobile phones, fax and other peripherals into the overall design of locomotives, passengers can also enjoy music, movies, video games, shopping, Internet and other services in the seat through the plastic optical fiber network.
In military communication, POF is being developed for high-speed transmission of large amounts of the third and confidential information, for example, using the POF characteristics of light weight, flexibility, quick connection, suitable for portable wear, for soldiers wearable light computer systems, as well as can be inserted into the communication network to download, store, send and receive mission critical information, and displayed on the helmet display.
With the development of POF manufacturing technology and raw material preparation technology, the production cost of POF will continuously reduce; from the current development situation of laser, optoelectronic integrated device and connector, with the continuous expansion of production scale, we believe that the cost of sending and receiving devices will decline significantly, so the POF has more advantage in access communication.
What is plastic optical fiber? Plastic Optical Fiber (POF) is definitely an optical fiber which is made out of plastic. Because the late 1990s however, much higher-performance POF based on per fluorinated polymers has begun to appear available on the market. Plastic optical fibers are popular Nowadays.
Fiber technology is constantly on the become more flexible and less expensive. Plastic fiber optic cables are made from just one acrylic monofilament and are most efficient when used with visible red status indicator light sources. Plastic fibers are generally more cost effective than glass fiber optic cables and therefore are well suited for applications that need continuous flexing of the fiber. A wide range of fiber optic tips can be found.
In contrast, plastic optical fibers use harmless green or red light that is easily visible towards the eye. They may be safely installed in a house without risk to inquisitive children. A second advantage is their toughness. Plastic optical fibers tend to be thicker than glass optical fibers, a millimeter or more, and could be handled without special tools or techniques. You don’t have to be trained to handle and do the installation. You simply work with scissors, hook it up and it works.
In large-diameter optical fibers, 96% from the cross section is the core that enables the transmission of sunshine. Much like traditional glass optical fiber, POF transmits light with the core of the fiber. The core size POF is in some cases 100 times bigger than glass optical fiber.
POF has been called the consumer optical fiber since the fiber and associated optical links, connectors, and installation are all inexpensive. The per fluorinated polymer fibers are generally employed for much higher-speed applications for example data center wiring and building LAN wiring. POF, using its large core, continues to be likely to function as the office and residential network media. Its large core permits the utilization of cheap injection-molded plastic connectors which can significantly lower the total link cost. But POF features its own problems. The most crucial obstacle is its high signal loss (attenuation). PMMA has been used because the light guiding core for commercially accessible step-index POF and PMMA’s attenuation is about 100 dB/km. This high attenuation significantly limits POF’s applications in data communication applying a lot more than 100m.
Here is the good news though. Developers have discovered that PF amorphous polymer based gradient-index plastic optical fibers get rid of the attenuation problem with PMMA based plastic fiber. They’ve developed PF-polymer based Gradient-Index (GI) POF with attenuation level of only 10 dB/km. According to theoretical calculation, PF-polymer based GI POF can achieve similar degree of attenuation as silica-based glass fiber of 0.3dB/km.
Having a optimized refractive-index profile within the PF-polymer based GI POF, a lot more than 10Gb/s data transmission speed can be achieved over 1km. This is the metrics of PF-polymer’s low intrinsic loss and low material dispersion. Coupled with this theoretically possible high bandwidth and occasional total link cost, PF-Polymer based gradient-index plastic optical fiber includes a huge potential in fiber optic data communication applications.
With really large diameter, the POF cable is simple to run along skirting boards, under carpets and around tight corners. It offers additional durability for uses in data communications, as well as decoration, illumination and industrial application. FiberStore can supply both simplex and duplex plastic optical fibers. Our standard color is black. Other colors are available upon request.
The plastic optical fiber (POF) constituts that the optical fiber core and cladding are made of plastic material. Compared with large core diameter 50/125um and 62.5/125um quartz glass multimode fiber, plastic optical fiber core diameter is up to 200-1000um, while continuing to use without the optical fiber positioning sleeve cheap injection-molded plastic connector, even The fiber splice SMIC alignment generated the ± 30um deviation does not affect the coupling loss. It is plastic optical fiber structure gives the quick construction, connecting and low cost. In addition, the core diameter of 100um or larger and it is possible to eliminate noise in the the mold presence of the multimode fiber of quartz glass.
In recent years, Europe and Japan and other countries made important progress in the development of POF fiber. The development of plastic optical fiber, optical loss rate has dropped from 25 to 9 dB/km. Its wavelength has been extended to 870 microns (near infrared light), close to the practical level of the quartz glass fiber. United States developed a the PFX plastic series fiber has excellent anti-radiation performance. In addition, Boston, Massachusetts, fiber developed the Opti-Giga plastic optical fiber is compelling, it is not only lighter than glass, flexible better, lower cost, and data transmission speed of 3 megabits per second in the 100 meters . Such a fiber can also use the refraction of light or optical fibers within the jump way to achieve a higher transmission speed. Now the United States and Europe has plastic optical fiber used for short-distance transmission, such as automotive, medical equipment, copiers.
Japan attaches great importance to the application of plastic optical fiber, several years ago, NEC, Fujitsu, Sumitomo Electric Industries, Inc. 45 optical communications, multimedia products manufacturers jointly announced, will work together to achieve the plastic optical fiber have been successfully developed in Japan practical use. Plastic optical fiber production, Japan is also the world’s largest producers of plastic optical fiber, however, in Europe to promote the development of new applications of plastic optical fiber and fiber inspection standards. The second half of 2001, the European plastic optical fiber industrial development stage, this time to establish a new approach to development of the European plastic optical fiber test and measurement. The world’s first dedicated Plastic Optical Fiber Application Center (POFAC) in Nuremberg, Germany completed. Germany using plastic optical fiber has been developed multimedia bus system MOST (24Mbit/s), and several car manufacturers, the system has been incorporated into their products. BMW has created a record 100m plastic optical fiber in the new 7 series. Europe 2001 plastic fiber Symposium and European Fiber Communication Conference held in Amsterdam, the Netherlands. German automotive industry not only to promote the application of plastic optical fiber, but also contributed to the establishment of the plastic optical fiber test and measurement standards.
Japan has also established a plastic optical fiber standards, but these standards to the European Community is invalid. Japanese Industrial Standards is given only for the standard of a new type of plastic optical fiber, a numerical aperture of 0.5, and only the 650nm wavelength. The standard does not mention the different excitation light conditions in the plastic optical fiber, there is no provision must be formed in the plastic optical fiber equilibrium mode distribution.
Plastic optical fiber, compared with the glass fiber, although the light-transmitting differential, light loss is large, the initial ships of 300 dB/km, the transmission optical narrow band (limited to the visible region), is that it is difficult to adapt to the needs of the multimedia communication network, but it has light and soft, flexural, impact strength, cheap, anti-radiation, easy to process and can be made (1 to 3 mm in diameter, in order to increase the light-angle, expand the scope of) a series of advantages, so favored. In addition, the light passes through the central portion of the plastic optical fiber diameter of about 1 mm, about 100 times larger than the glass fiber, and the connection between the fiber connection and personal computer terminal apparatus is very easy. Plastic optical fiber installation costs low, very simple installation can align the connector plug, this plug can be used existing technology to produce.
The plastic optical fiber as the ideal short-range communication network transmission medium, in the future family of intelligent, office automation, industrial control network. Car airborne communications network, has an important position in military communication network and multimedia equipment in the data transmission.
Using plastic optical fibers, we can realize the smart appliances (home PC, HDTV, phone, digital imaging equipment, home security equipment, air conditioning, refrigerator, sound system, kitchen appliances, etc.) networking, to reach home automation and remote control and management, improve quality of life; through plastic optical fiber, we can achieve office equipment, networking, computer networking can achieve parallel processing computer, high-speed transmission of data between office equipment can greatly improve the work efficiency, remote office?
Low-speed LAN 100Mbps data rate is less than the transmission within 100 meters of with SI index plastic optical fiber to achieve; within 150Mbps50 meters transmission used a small numerical aperture of POF achieve.
POF cable is available a wide range of applications in the manufacturing industry. Converter, POF connector with RS232, RS422, 100Mbps Ethernet, Token Ring and other standard protocols, resulting in harsh industrial manufacturing environments to provide a stable, reliable communication lines. Capable of high-speed transmission of industrial control signals and instructions, to avoid electromagnetic interference by using a metal cable lines lead to the risk of interruption of communication transmission.
With the development of science and technology, more and more fields of application of plastic optical fiber, the development of the market will be more and more broad. Abroad on the application and development of plastic optical fiber has been achieved greater results, and continue to increase applied research investment, South Korea, China and Taiwan manufacturers have begun to develop production, the industry should be on the plastic optical fiber of research and development to be closely watched.

The classifications of plastic optical fiber cable
Common plastic optical fiber cable
Including all the multimode optical fiber plastic, graded-index multimode plastic optical fiber and single mode optical fiber. This kind of optical fiber is similar to ordinary quartz optical fiber, made up of fiber core and cladding, constitutes the fiber core refractive index distribution of different types of optical fiber.
Multimode fiber is mainly used in strength type sensor system, the measured quantities directly affect the intensity of output light signal. The gradient refractive index multimode plastic optical fiber can solve the problems of the belt width.
In single mode fiber and single mode quartz optical fiber core are the shortcomings of the core diameter, only 5 ~ 10 microns. Single-mode fiber and plastic is relative to the characteristics of quartz optical fiber core diameter thick, 50 ~ 100 times that of silica fiber, docking easily, low cost, so its in interferometric fiber optic sensor has the more outstanding characteristics.

Plastic optical fiber with its soft, flexible, large core diameter, coupling, resistance to electromagnetic interference and electromagnetic radiation (EMR) EMI, low cost, widely used for short, medium and small capacity, information transmission system, sensors, CD players, cars, planes, multimedia information transmission network, military network, and even can be used in the space and missile guidance, etc.
As a transmission medium, because of its unique performance, POF plastic optical fiber attracting attention around the world. However, plastic optical fiber loss big shortcoming has been restricts its wide application in various fields. With the continuous improvement of chemical technology and related scholars in the field of continuous efforts, POF has in LAN, CAN, OFS and other fields to achieve the practical application. POF research and production in China is relatively backward, and current domestic POF for advertising, decoration, and the application in the field of industrial, electronic and communication is almost blank. Further improve chemical technology, maintain POF the systematicness of the research, development and sustainability is the urgent task that we are faced with.
Plastic optical fiber (POF) is by high-transparent polymer such as polystyrene (PS), polymethyl methacrylate (PMMA), polycarbonate (PC) as the core material, PMMA, fluorine plastic, etc. as cortical material class of optical fiber. The type of material having different optical attenuation performance and temperature range of applications. The plastic optical fiber can not only be used to access network 100 to 1000 meters, can also be used for a variety of cars, aircraft, and other delivery vehicles, is excellent in the short-distance data transmission medium.
POF compared with quartz fiber has the following advantages: a low modulus, large core diameter (0.3-1.0mm), can use a simple continuation POF connector, it will not affect even the center of fiber optic splice the deviation of the alignment 30μmcoupling loss; Large numerical aperture (about NA0.5), the acceptance angle up to 60 °, only 16 ° quartz fiber available cheap LED and high coupling efficiency; deflection, ease of processing and use; low loss in the visible regionwindow; light weight; costs and low processing costs.
POF Network LAN system in comparison with other transmission medium, and also has obvious advantages: POF is not sensitive to electromagnetic interference radiation does not occur, the different attenuation constant data rate, bit error rate can predict in electrically noisy environment used; joint design tolerances control requirements can be reduced its size is longer, and therefore into a network and low cost.
The plastic optical fiber as the ideal short-range communication network transmission medium, has an important place in the family of intelligent, office automation, industrial networking, automotive airborne communications network, military communications network, data transmission.
Through the plastic optical fiber, we can realize intelligent home appliances, home PC, HDTV, telephone, digital imaging devices, home security equipment, air conditioning, refrigerator, sound system, kitchen appliances, etc.) networking, to home automation and remote control and management, improve living networking quality; through plastic optical fiber, we can achieve the office equipment, such as computer networking computer parallel processing, high-speed transmission of data between the office equipment can greatly improve work efficiency, and remote office.
At low speed LAN 100Mbps data rate is less than the transmission within 100 meters of with SI index plastic optical fiber to achieve; within 150Mbps50 meters transmission used a small numerical aperture of POF achieve.
Currently, POF is also available a wide range of applications in manufacturing industries. By converter, POF can connector with RS232, RS422, 100Mbps Ethernet, Token Ring and other standard protocols, resulting in harsh industrial manufacturing environments to provide a stable, reliable communication lines. Capable of high-speed transmission of industrial control signals and instructions, to avoid electromagnetic interference by using a metal cable lines lead to the risk of interruption of communication transmission.

On Military Communications, POF is being developed for high-speed transmission of a large number of third, confidential information, such as the use of POF, light weight, good flexibility, quick connection, suitable for portable wear characteristics for the soldiers wearable light computer systems, and can be inserted into the communication network to download, store, send, receiver mission critical information, and displayed in the helmet display.
With the continuous advancement of POF manufacturing technology and raw materials preparation technology, the cost of production of POF will continue to decrease; see from the laser, the development of optoelectronic integrated devices, connectors, domestic and international technology has made rapid progress, with the there will be a sharp fall with the continuous expansion of production scale, it is believed that the cost of sending and receiving devices, POF access communication advantages.
In the field of communication that optical fiber have been used for many years, but when it comes to optical fiber communication, most people will associate it with “high-end” together. Indeed, optical fiber transmission capacity is big but it’s loss is small. However, if you want it big enough to the optical fiber communication network deployment, small enough to the fusion of optical fiber links, connection and test, both of them have very high requirements on technology and equipment. And high costs, material are limited so that it is not applicable to some situations.
To some extent, the emergence of the plastic optical fiber solves the fiber optic popularity in a series of problems, ultra-high transparent plastic or resin fiber, fiber toughness can be greatly improved, no longer appear easily optical fiber wire core fracture problems. Can also move the optical fiber, solves the problems of fiber material in the local area network (LAN) vulnerable, and reduces the equipment cost of fiber materials production and processing, this will be a technology revolution about fiber products.
In the FTTH solution, the connection of quartz optical fiber is difficult, production cost is high, the system installation and maintenance cost is high, increasing the cost of FTTH construction , and increase user’s burden, hindered the further promotion of FTTH. Plastic optical fiber became the best choice to solve this problem, use of plastic optical fiber with quartz optical fiber, at the end of the FTTH fiber optic cable access will have a big effect, which can solve the last few hundred meters of fiber access problems. Plastic optical fiber with light weight, flexible, good flexible, corrosion resistant, moisture proof, shockproof explosion-proof, no electromagnetic interference and radiation, confidentiality, security and does not change with transfer status, therefore, the plastic optical fiber will become the strong competitors and even copper networks substitutes.
In developed countries, the plastic optical fiber is used to replace five/six kinds of copper networks and used in the home network, is a kind of affordable optical fiber. Telecom companies in Europe and North America and European Union plastic optical fiber has been testing the plastic optical fiber, they think this kind of medium is easy to install, low prices, flexible and not damaging to eyes.
Compared with the traditional optical fiber, plastic optical fiber has the energy conservation and environmental protection, simple installation, low maintenance cost, strong confidentiality, lightning protection electricity etc. Plastic optical fiber also get the attention of the enterprise and related personnel, and has wide application prospect in the market. But compared to the international market, plastic optical fiber in domestic has not been true for approval, the industry of plastic optical fiber, mainly focused on its loss, costs, and industrial support. Optical communication field’s famous expert professor Mao Qian believed that an objective orientation, for plastic optical fibers is the precondition for the development and application of plastic optical fiber. Plastic optical fiber is not to replace silica fiber, but complementary, in terms of solving short broadband connections, plastic optical fiber has obvious advantages.
With the broadband of China’s boom, FTTH become the new era, different construction technology for copper wire, silica fiber door to bring a great test of the construction team. In telecommunications research institute deputy chief engineer of Beijing Zhang Chengliang said: “the actual installation in FTTH, home wiring problem still brought great trouble to engineering.” Because of its high rate of plastic optical fiber, strong mechanical performance, the operation of the civil procedure, during the construction of a household, has already become the most ideal medium last 100 meters of FTTH.With the union last year, China plastic optical fiber industry, the coordinated development of all the vendor implementations, plastic optical fiber industrial chain from industry towards the application of mature, in the domestic policy, the 12th five-year plan, such as power, plastic optical fiber industry market will have a leap.
Plastic optical fiber parties advantages are undisputed, the current has both domestic policy, and there is a market for attention, although in terms of industry chain, technology is not mature, but should grasp opportunities for development, the future of China’s broadband development, plastic optical fiber will lead the industry trend.
Cost in the short distance communication transmission is quite the same as symmetrical cable for Plastic optical fiber (POF). In the 100 – meter range transmission bandwidth can be up to high GHz, transmission bandwidth has easy connection, good flexible, easy bending and other advantages, while the performance of the system is still in its early stage, but it is the role of the short distance communication in the future can not be ignored, the advantages of price and performance, FTTH fiber optic cable(Fiber To The Home) has bright prospects.
Plastic optical fiber as an ideal transfer medium for short distance communication network, in the intelligent household, office automation, industrial control network in the future, vehicle-mounted, airborne communications network, military communication network data transmission plays an important role.
Nowadays, POF are widely used in the manufacturing industry, too. By optical transceiver,
POF can be linked together with RS232 and RS422, 100 MBPS Ethernet, etc. Thus in harsh industrial environments to provide stable and reliable communication lines. POF can avoid affected by electromagnetic interference caused by using metal cable line transmission interruption risk, too.
POF is light and durable, By means of linking on-board computer communication with operating system, network and form a network control system, micro computer, passengers can also enjoy music, movies, video games, shopping, Internet, etc through the plastic optical fiber cable.
Compared with other transmission mediums, POF network in the local area network (LAN) system has obvious advantages: POF is not sensitive to electromagnetic interference, radiation occur, attenuation constant under different data rate. Its size is longer, can reduce the requirement of tolerance in the design of joint control, so the network is cost saving.
In military communications, POF are being developed for high-speed transmission of the confidential information. Take good use of POFs light weight, good flexible, quick connect, and can be inserted into the communication network to download, key task information storage, sending, receiving, and display in the helmet mounted display.
With advanced POF manufacturing technology and materials preparation technology, the POF will continually reduce cost of production, From the current development situation of laser, optoelectronic integrated device, connector, domestic and international relevant technological progress, with the expansion of the scale of production, trust to send and receive device costs will be reduced greatly, make POF in access to communication.
Today’s technology development is an urgent need to large capacity optical fiber materials.
Plastic optical fiber has a large core diameter, texture is soft, easy connection, light quality, cheap price. And the advantages of large transmission bandwidth, system hook in broadband, home intelligent network system, data transmission systems, intelligent systems, industrial control systems and textile, lighting, etc. The application of solar energy utilization system market has huge potential. In addition, some cities have proposed to upgrade Chinese telecommunication networks, to speed up the pace of optical fiber to the home fiber cable.
POF research on key institutions and organizations are the United States POFTO, France POFClub, Japan Association of POF POF Association, recently organized by the South Korean government and the German POF Application Center (POFAC) established in Nuremberg University, Germany Alliance. POF as ideal for short-distance communication network transmission medium is becoming more and more important in the future family of intelligent, office automation, industrial networking and automotive airborne communications net. The same time, we should see further development of the POF industry also encountered some obstacles, such as:
(1) in the current LAN, compared with the existing copper cables that can be upgraded, the use of plastic optical fiber, the cost is still relatively expensive, making ready for a new cable business, will consider the utilization rate and price of the fiber optic cable Is it cost-effective. Therefore, the transition from copper wire to the cable is still a relatively slow process.
(2) lack of market awareness, research institutions, not too close and cooperative relations between the enterprise, resulting in some technology even if was not practical to make substantive progress. Enterprises are more difficult to market with the technical aspects of information.
(3) ATM Forum in May 1997 by 155Mbpa POF and standard hard plastic cladding, but the development and improvement of the uniform standards of the industry as a whole but progress has been slow, which is not conducive to the industrialization of the plastic optical fiber.
(4) POF developers target set too high, the main energy into high-end industries, these industries require higher barriers to entry and more advanced technology makes this should become the POF the mainstream market is still a large number of use copper. POF should be low-end industries as the cornerstone of the gradual occupation of these markets, and then enter the high-end industry.
(5) the lack of a strong business associations to promote the development of POF.
(6) lack of related courses in colleges and universities.
