The concept for many people may still unknown, but long ago, the Chinese Academy of Sciences Chemistry, China University of Technology innovation projects undertaken by Chinese Academy of directional polymer optical fiber local area network project through acceptance, which allow people to have a plastic optical fiber further understanding. Through their efforts, so our research in this field has reached the international advanced level. Acceptance of the Expert Group that created the project with the original innovation of broadband, low loss graded refractive index polymer optical fiber (GIPOF) preparation of patent technology, process simple, convenient and suitable for industrial scale production. However, this can quickly realize the outcome of industrialization, whether the market competitive in the field of optical communication in a favorable position? To this end, the reporter spoke with Chinese Academy of Sciences study of Chemistry is involved in several of the project, Dr.

  International advanced technology project Han Bu-Xing is the one responsible for this research team, he said that at present, their project has received national ’863 ‘program of new materials in the field and the State Planning Commission to support industrialization demonstration project.

It is understood that the present communication backbone is generally used quartz optical fiber, due to its core is a very small, in the fiber-coupled, high-precision targeting Internet access is required, which greatly increased the cost of connecting the quartz fiber , restricted in their contacts and more short distance transmission fields. To reduce the short-distance optical fiber access networks, fiber-optic network users access costs, Japan, the United States and other developed countries, universities and companies have developed a new generation of short-distance optical transmission media??? Plastic optical fiber.

CAS chemical in plastic optical fiber of the discussion group has proposed an and Foreign patents and literature completely different, original technological innovation, economic and technical feasibility are reasonable gradient refractive index polymer optical fiber preparation method, with completely independent intellectual property rights, to break the blockade of international patents. Currently, they have successfully prepared 100 m POF samples, and using the polymer fiber developed and successfully applied to the connection between two computers, to achieve high-speed multimedia data transmission.

Market value of different opinions The plastic optical fiber project, CAS Chemistry hopes to enter the fastest speed industrialization. However, several PhD that the smooth progress of industrialization will depend on whether the choice of the market. The current market has to be more popular which access, there are a number of domestic disputes.

Introduced, according to Han Bu-Xing, a number of optoelectronic devices in the network or an expert on plastic optical fiber project put forward different views: they think that the quartz glass fiber technology is very mature, access to the desktop no problem, and the current Copper technology is also able to meet some needs, there was no need to do plastic optical fiber; another in the distance, the plastic optical fiber technology currently only applies to 100 m transmission over 100 meters of plastic optical fiber for optical transmission loss is too large, been restricted.

But one task force member Dr. Zhang Shimin were particularly emphasized that the greatest advantage of the plastic optical fiber is cheap, good flexibility, easy processing, easy operation, long life, light, and thus short transmission has the absolute advantage.

Short-distance transmission have obvious advantages

Cables, optical fibers, plastic optical fiber, in information transmission in the market will choose what kind of transmission media? Dr. Zhang Shimin that, while now most of transmission backbone using quartz glass fiber, but in the short-range access on the overall cost is relatively high silica fiber, silica fiber-optic technology now even the highly developed United States and Japan are still not large-scale access to Desktop and households, its price and difficulty of access technologies is difficult for users to accept the two main factors, silica fiber and flexural properties of brittle materials as well, not suitable for multi-junction access.
