Fiber to the home of great concern Technology With a sudden turn for the better battle last year, China Telecom also strongly experiments using EPON technology, now EPON and GPON technologies into pilot go hand in hand, while the GPON that is foreign owned factories have been strongly recommending the technical standard finally in China, a survivor.
First GPON trial started
As the existing rate ADSL can provide only 512K to 4M, has not and is currently being launched in 3G Competition, therefore, greatly enhance the fixed network operator rate is imminent.
However, the use of technical standards has been debated what to do. After a few days, Sina Technology has reported that China Telecom will adopt FTTH DSL technology and synchronous way forward, but there FTTH GPON and EPON technology has two technologies compete.
Beginning in 2007, China Telecom will carry out pilot projects with EPON, and pilot-scale growing. Informed sources, China Telecom this year, suddenly decided to GPON pilot.
Learned, as early as February-March this year, China Telecom will carry out a pilot GPON Tender . The China Telecom GPON total of 13 test points, flames, Huawei, ZTE and Shanghai Bell and other companies to participate, of which Shanghai Bell was one of the five.
The pilot cities, including Beijing, Shanghai, Wuhan and Hangzhou, GPON bandwidth download speeds of up to 2.4G per second and upload speeds of up to 1.2G per second. Chinese and foreign firms compete
technology
GPON and EPON struggle between the two technologies actually more a struggle between Chinese and foreign technology firms. Ericsson, Alcatel-Lucent and other telecom equipment giants are several international GPON technology, GPON trial network in the world Market Major share of possession, it highly recommended GPON technology, and war and other domestic light Communicate Strong Enterprise EPON technology is advocated. GPON and EPON
technology in the end about who is better and different opinions in the industry. Technically, GPON transmission convergence layer, whether in business or in the adaptation layer is more efficient, but because of high technical complexity, GPON has been higher than that in the cost of EPON, and it has not been a real large-scale business. The EPON users per line construction prices have dropped to 700 yuan, with the maturity and cost advantages.
China Telecom attitude change GPON and EPON
in the attitude of technology, China Telecom has repeatedly changed. Last year, an industry
Meeting , China Telecom Group Science and Technology Committee, said Wei Leping, “In addition to drastic reduction in the cost of years of development, now has achieved EPON chip-and system-level equipment interoperability, and this is a technical assessment can operators the importance of commercial operations Standard . For the present, many manufacturers strongly promoted GPON (ITU standard based on the latest generation of broadband passive optical network) technology, although with better quality, management, and multi-service functionality, but industry is not mature enough, high cost, not the current operators the best choice. ”
Held in the recent seminar on optical networking, Wei Leping also said that although at this stage behind GPON EPON (the current net market, standards development and maturity of the industry chain, etc.), but considering its GPON features more than EPON not far off when the mainstream standard.
