A new generation of multimode fiber

1 multi-mode fiber has been the subject of network transmission medium, stable market share in the share of world fiber. With the upgrade of the network transmission speed and vertical cavity surface emitting laser (VCSEL) using a new generation of multimode fiber is about to come out of international standards. Application in single-mode fiber trunk growth rate gradually become saturated situation, introduction of new standards will undoubtedly promote the development of network applications and multi-mode optical fiber and the industrial development of new varieties to bring new life opportunities.

2 theory, although there are plastic optical fiber network transmission medium, such as five or six cable, Bluetooth wireless communications solutions, they have their own advantages. However, the application of technology and system perspective, multi-mode fiber is still the first choice can not be replaced. Plastic optical fiber transmission loss at present to more than a few dB / km, 1 ~ 3Gbit / s perfluorinated graded-index plastic optical fiber just research institutions and universities in Japan, the successful development, not yet commercially available. Its not a good loss and bandwidth characteristics, and multi-mode fiber comparison. Another drawback of plastic optical fiber is flame retardant as the quartz fiber. Five or six cable transmission rate of increase with the rapid increase in loss, five cable transmission rate at 100MHz, each 100 m loss is 22dB. Bluetooth technology, no wiring and can be connected to mobile terminals, but the role of distance is limited, to enter the LAN to go through photoelectric conversion. These technologies in the future will (now) in some suitable occasions, but the overall look LAN applications, multi-mode optical fiber in nearly two decades will continue to dominate.

3 multimode fiber supply and demand situation the world is not like the trunk with large quantities of single-mode fiber as dramatically. Multimode fiber in China had exported, domestic demand also rose steadily. With the new generation of multimode fiber introduction of international standards, with a fiber network to accelerate growth and China has entered WTO, the formation of such a large environment, suggested that the domestic industry due consideration to the new multi-mode optical fiber development and production, to meet the new domestic and foreign markets development needs. Proposed research units to track the contents of the new international standards, new standards after the implementation of market and industry trends; be able to obtain a new generation of multi-mode optical fiber production technology and testing techniques, the development of new technology with the world's fiber-optic integration; and then as military hospital, as for participation in the international postal optical fiber communication the new standard-setting.http://www.chinaopticcable.com
