subject: Plastic Optical Fiber Into The Ftth Market [print this page] HC plastic mesh information: plastic optical fiber communication with the quartz fiber, in the end FTTH (home cabling) will play an important role, not only can solve the "last few hundred meters," the access problem, using plastic optical fiber to reduce the energy consumption of the copper.
2010, the operators continue to broadband speed, 4M, 8M or even 20M access bandwidth, has become the access network construction and transformation of the new target. To achieve higher access bandwidth, FTTH forward to bear the brunt of China Telecom, plans to open in 2010 and one million lines of FTTH subscribers, China Mobile and China Unicom also accelerate FTTH deployment.
Guarantee the smooth implementation of FTTH, PON equipment has been used in the case of a very mature, buildings and indoor fiber optic cabling into the last hurdle to promote FTTH. Operators continue to test and regulate the routing programs and standards, cable providers are constantly improving interior wiring systems.
Plastic optical fiber (POF) R & D is the industry one of the most popular field of study. POF with its large core diameter, good flexibility, plasticity, light weight, low cost of being international attention. Therefore, use of communications with the quartz optical fiber POF, in the end FTTH (home cabling) will be effective, can solve the "last few hundred meters," the access problem. On the other hand, at present, promoting low-carbon building society, the use of more environmentally friendly plastic optical fiber, the relative five lines, and copper products, but also more competitive.
2010 5 25, at the Beijing University of Posts and Telecommunications, from telecom operators, universities, research institutes, experts and manufacturers of plastic optical fiber, optical fiber to plastic will play a role in the local area network cabling and to better serve low-carbon society, in-depth discussion.
King of short-range wiring Communications with the core diameter POF rough, easy coupling, without welding or soldering, light weight, excellent flexibility, flexible, anti-corrosion, anti-moisture, shock proof, no electromagnetic interference and radiation, confidentiality, security and anti- interference ability and the attenuation constant, the state does not change with the transmission characteristics, therefore, communication with POF is a strong contender as well as copper alternatives.
Plastic optical fiber cabling system can be used as intelligent building, computer network transmission solutions. Since the wiring system has been created after the universal application of the system to a building or a computer network computer network terminals, each connected by plastic optical fiber to form a complete network.
Parts according to their position in the architecture and function of different plastic optical fiber cabling solution, commonly used conventional vertical lines such as multi-mode quartz fiber optic cable. Plastic optical fiber connection points are used in many levels of the system, for solving the horizontal direction from the working area network switch to the computer needs of large data transfers. Horizontal data connection, the optical fiber connection to the desktop workstation, as the number of connections more than the traditional quartz fiber in terms of cost, engineering, maintenance or management are more difficult to achieve universal application. The large diameter plastic optical fiber, it is easy to implement fiber optic termination, coupling and laying the construction of cable minimum bending radius, installation environment requirements are also low. Therefore, high-end all-optical cabling system, gigabit network systems and anti jamming, signal leakage wiring system can be compared with other types of transmission line advantages.
Plastic Optical Fiber Co., Ltd. Jiangxi Story fiber has been formed using self-produced all-plastic optical fiber LAN, network television programs, including IPTV, VoIP Internet phones, cell streaming media server (available to subscribers on-demand high definition television), ipcam network digital surveillance, network HiFi stereo, internet internet, network users on demand server education programs, music, games and high-definition television programs, networks are all the distance from 100m. And in April 2009 at Shanghai Jiaotong University, the regional fiber-optic network and new Optical Communication Systems State Key Laboratory of Yangtze River Delta 3T-bandwidth all-optical network system, the establishment of a plastic optical fiber network system model, in July 2009 experiment in Jinggangshan City schools to establish a plastic optical fiber network system, and achieved good results.
