Chinese telecommunication start optic fiber to household commercial

In August, the China Telecom Corporation has completed to 40,000 EPON (ether passive light network) equipment's central buying, and completes "Chinese Telecommunication EPON Equipment Specification V2.0" and so on related enterprise standard formulation. hence, the Chinese telecommunication draws the conclusion, uses in realizes FTTH (optical fiber to household) the EPON technology already achieving the commercial level, the resurgence, the beacon-fire, the long light, Grimm Will, the arrogant letter and so on six equipment provider's EPON equipment conforms to the Chinese Telecommunication enterprise standard, next year various provinces company may the independent choice, purchase the EPON equipment, develops FTTH according to the market requirement.

　　EPON first breaks the bureau

　　“not only this collection will pick will drive the Chinese telecommunication various provincial offices' EPON network construction, will also affect the domestic other operator's decision-making.”Beacon-fire correspondence Chief Technology Officer Gao Peng indicated that “will also have the influence to the equipment provider's product route, causes certain to concentrate in researches and develops GPON the factory to transfer enlarges to the EPON research and development investment.”

　　At present, the Chinese telecommunication had already determined the FTTH technical route, namely “uses technical mature EPON first, continues to follow up the GPON progress”; Chinese telecommunication's FTTH is not reaches one's goal instantly, but with every effort unearths the copper cable resources, in the near future by FTTN+DSL (optical fiber to the node + each kind of DSL technology, like ADSL2+, VDSL2 and so on) the plan primarily, will realize “the light to enter the copper gradually to draw back”. The above development mentality is China Telecom Corporation Chief Engineer Wei Leping talks about many times, but this collection picks is precisely launches according to such mentality.

　　From technological strength's angle, EPON and GPON, is merely the technical principle is different, its network pattern, service turning on ability, the project implementation and so on are identical. “the Chinese telecommunication the experience which accumulates in the EPON commercializing advancement may use in including GPON, WDM-PON, the P2P light ethernet and so on all light turning on application.”

Resurgence communication turning on product Chief Marketing Officer Xu Zhicheng expressed.

　　This FTTH purchase's influence is also not limited to this. In the FTTH whole solution, the optical fiber and the EPON equipment's funding invested is 1:3, therefore the FTTH large-scale construction will also promote to optical fiber market prosperous. But so on needs the high band width regarding IPTV the video frequency service, FTTH will improve the user experience obviously. “this will also accelerate the video frequency service the promoted advancement.”The Shanghai telecommunication is responsible for Engineer IPTV network construction express.

　　The related expert forecast that next year the Chinese telecommunication various provinces company will increase the EPON equipment's purchase, south the Chinese telecommunication various provinces will have 200,000 above demands in the future; Next three years, the FTTH number of users will maintain every year 2-3 time of rates of increment.

　　The collection picks the beginning to end

　　Although this collection picks quantity not to be big, but the Chinese telecommunication altogether has 16 province companies to participate, north the telecommunication takes a provincial office to participate, in fact nearly all provinces participated in the EPON equipment's collection to pick. Behind the merely 40,000 EPON equipment purchase, is the China Telecom Corporation and various provinces company to EPON and the GPON technology lasted more than two years of measured that the track, the test and try commercial.

　　April, 2005 to May, 2007, the Chinese telecommunication organized the system equipment factory and the chip factory successively has carried on the EPON system 4 rounds the test, was last test is in March 26, 2007 to April 30, its test result did for this collection picks the technical part grading main basis.

Must think on the FTTH equipment to integrate the service, needs to have the profound understanding to the service, but the different country as a result of political, cultural, the use custom's difference, causes different national the service difference to be very big. “compares with the overseas factory, the domestically produced manufacturer is more profound to China's service demand understanding, this is also the domestically produced manufacturer wins in this FTTH purchase the primary cause.”Gao Peng indicated that “this purchase is the market choice result completely, does not have the country and the operator to home equipment's being partial.”

　But, this kind the equipment integrates the service and EPON the pattern also has certain malpractice, theoretically, the equipment and the service separation is the next generation network trend of development. “looking from the short-term, this kind of pattern may help the operator to provide the service rapidly, because the big factory reliability is high, operator's service stability also increased; But in the long run, in this kind of pattern's big factory has monopolized the equipment and service these two links, enables certain to have the innovative ideology small manufacturer without knowing where to begin to participate, does not favor operator's service innovation and to the industrial chain's leadership.”Xu Wei expressed.
