Optical communication: Extend the lively quotations EPON and compete with GPON and ease up
The optical communication industry of China may be one year reaping in 2009, are built by the operator broadband, 3G and driven the heat degree of the market to remain high in the whole year. Operator purchase scale, go beyond the beginning of of 2009 anticipated mostly finally. Take China Mobile as examples, plan to purchase 16 million core and one kilometer of optic fibres at the beginning of the year, the final amount of purchase is up to 18 million core kilometers. Because operator’s networking has certain persistency, the high-speed developing state of the market of optical communication will last 2-3 years at least.
It lasts 2-3 years at least to grow at top speed
Optical communication market prevail let the intersection of industry and income a lot, this year, also initiated the worry whether people could grow at top speed to the market continuously. How does the general trend of market development of optical communication becomes the focus that everybody pays close attention to this year.
The telecommunication research institute of the department plans to transmit and represent ” China’s electronic newspaper ” reporter with Deputy Director of access network research department He JianWu clearly in the research institute: “According to market trend at present, the high growth of the market of optical communication will also last 2-3 years at least. The major cause is that the construction scale of the operator is very enormous, it will be impossible to all finish constructing in 2009, a lot of construction plans of operator, for example 3G cloth network, broadband staging,etc. take several years and can be finished. ”
In fact, the excellence of optical communication has just begun. In feasibility and cost, FTTx large-scale and commercial condition has been already ripe. FTTx industry really stepped into the construction phase of the scale by concept and pilot project, visits generally benefited trade chances from head to foot as the industry chain, optical communication is prosperous will last. In addition, 3G is the mobile communication of the broadband, accords with the communication development trend, its induced effect on optical communication will be for many years.
The high-speed growth origin of China optical communication market lies in the active demand developing broadband service.
As a whole, the broadband of China is still at low-level stage. OECT (international economy and cooperative association) The downstream speed of the average network of international organization has already reached 17M, and a lot of Chinese users are also broadband of inuse 512K at present. The investigation report that U.S.A. communication association releases reveals, China arranges in 47th in the whole world in Internet’s network speed. So though China has already become the country that global broadband has been most in number of users, but still is at the stage of broadband of low speed, and countries such as Japan and Korea S.,etc. have very great disparity.
CHINAUNICOM’s broadband service employs the national project Tang XiongYan, vice chief engineer of laboratory to think: “China is the big countries of the broadband, but not a powerful country of the broadband. By the look of development of business, we have already entered the era of broadband 2.0 now, that is to say a large number of video business becomes the body of the whole of Internet’s business, users produced a lot of contents, in addition P2P (individual is to individual) too by oneself The business becomes the mainstream too. In this case there is a more high requirement for the broadband access. ”
EPON competes with GPON and eases up
According to state of development of market of optical communication at present, FTTx will be the most important application this year. Two major mainstreams technological EPON (EPON) that there is FTTx at present And GPON (G one bit of passive optical networks) ,EPON was occupied to absolutely dominate the position in the past. But there will be new break-through in the 2009 development of GPON, China Telecom, CHINAUNICOM introduce the pilot project of GPON. Look according to the present development trend, EPON and GPON will be in China’s long-term co-existence, though both sides will still have competitive relation, not but ” Yes you have no me ” Relation. “EPON occupied China in the past and was close to 90% of the market share, occupied the absolute predominance position. But the recent operator rises to some extent in market share in course of expanding to the operating range of GPON, this kind of trend will be last until for 2011 years at leasted. ” Have a match, guide advisor communication the intersection of industry and the intersection of research center and Beijing Kong, Vice President of managing, reporter show to ” the the intersection of China and electronic newspaper “.
Ericsson GPON products and market support the director MichaelGronovius to say to ” China’s electronic newspaper ” reporter: “The chain of industry of GPON is developed comparatively more completely than EPON, the development foundation is a little better. Future development speed should be able to exceed EPON. The operator of China is improving to acceptance degree of GPON at present. ”
Just because of the transition of operator’s attitude of telecommunications, the apparatus trader great majority ” sit on the fence ” ,All put GPON and EPON into researching and developing. Some apparatus traders still develop xPON apparatus that can support EPON and GPON at the same time at the same time, aim at meeting the operator to various technical arrangement demands. At present, China has this kind of apparatus for, resurgence communication, beacon and Bell in Shanghai.
Certainly, the competition between EPON and GPON eases up, does not represent the two will totally ” lump together ” . Because operator’s previous technology puts into different from network planning, the operator FTTx builds still there is a technological difference in a short time. China Telecom EPON already scale has disposed the rank of Damien’s Line ten million, will rely mainly on the fact that EPON has been disposed in 2010. As to GPON, China Telecom launches GPON pilot construction in a plurality of cities of China, but the scale is not very large. CHINAUNICOM is similar to construction tactics of China Telecom. China’s moving access network tactics are that GPON, EPON both regards as equally important, and will choose GPON under the equal price preferably.
