Optical communication network technology and scale of development is synchronous
Optical communication is “light to transmit information ” of a kind of means of communication, its principle of operation is the sending end through the device, the information is converted to an optical signal, and then using optical fiber network transmission of the signal. The optical communication industry category, including optical fiber, optical communication equipment, optical communication components, due to optical communication product categories, long industry chain, with strong industry leading role, therefore, many of the world’s countries and regions have into the optical fiber network infrastructure construction, promote the development of optical communication industry.
American ” National Broadband Plan ” planning in 2015 100000000 users to download speed of at least 50Mbps broadband access capability; the British ” digital uk white paper” in 2017 to provide 90% home and business users of a new generation of high-speed broadband network; Japan ” light, ” where the goal is to make 100% 2015 home users access 100Mbps the above high-speed broadband network; Taiwan region of China’s ” Digital Convergence Development Plan “, in 2015 80% to provide home users can access 100Mbps CATV broadband network, optical fiber subscriber number amounts to 6000000, digital cable TV penetration rate of 50%. Optical communication optical fiber communication industry chip as core, are in each country and the area development plan of the core position.
Due to China’s optical communication network of high amount of investment, large scale construction, plans to make clear, China optical communication industry developing very fast in recent years. From the beginning of 2010, China optical communication network construction to large-scale access network upgrade, the three major telecom operators FTTx Jicai total about 20000000 lines. In 2011, China Telecom FTTx purchase amount is 19000000 lines, followed by China unicom. According to the State Administration of Radio Film and television programming, cable TV operators from 2011 start network transformation, will also purchase a large number of PON equipment.
In addition, for the optical communication, the technology mature, while business relatively insufficient demand. To be known as ” broadband access to the ultimate goal of” FTTH as an example, the realization of EPON technology has been fully mature, but due to the common user access required bandwidth is not high, the FTTH commercial only in some pilot areas. However, in 2006, with the IPTV three broadcasting business, operators provide bandwidth has been unable to meet the user ‘s requirements for high definition TV, then the FTTH deployment are also on the agenda. Similarly, ASON of transmission network flexible control, for enterprises to provide personalized customer service, many operators for the development and maintenance of corporate clients, invested construction ASON
However, China’s optical communication enterprises most business all around the fiber optic cable and optical equipment, optical communication chip industry overall still weak, products are mainly concentrated in the end.
High speed optical fiber communication industry, with the development of high performance computer and high speed of a phase in the development of high-speed, broadband, to short distance, low power optical transmission a marked increase in demand. From the national perspective, but also from the application and the key technology breakthrough, on optical communication enterprises increase give aid to strength, and formed a group of powerful core enterprise, enhance the market competition strength, open the domestic market, gaining sufficient economic benefits.
