FTTH: EPON or GPON?
Of: Zhu Jie
fiber access market heating up, a next-generation optical access technology opportunities brought about rapid development. However, the development of the future will be FTTH EPON or GPON has not led to quell the controversy. In May 28th at the 2008 Optical communications forum, the experts said, the product development capabilities, costs continued to decline in the space and use this product in the world who will ultimately determine the size of leading the future development of FTTH.
Technology who is more suited to?
fact, many operators do not care in the end is the use of EPON or GPON, what technologies to better meet the requirements of optical access to what kind of products and technology. From the perspective of market applications, EPON and GPON technologies in the international arena both have many supporters. EPON in Asia-Pacific region, especially Japan and South Korea occupy a dominant position. from the global market, especially the North American market, More operators are increasingly using GPON.

EPON in Asia-Pacific region, especially Japan and South Korea occupy a dominant position. from the global markets, especially in North America market, more operators are increasingly using GPON.
Ericsson China Communications Co., Ltd., Head of Marketing and Strategic Planning, often just said: GPON will be a mainstream technology. from next year after, GPON will dominate the market size in the size of. GPON offers higher bandwidth, more efficient bandwidth utilization, longer distance access; In addition, GPON provides full-service carrier-grade quality assurance is also very important aspect, because just say that the support of all business needs carrier-class quality of service as a guarantee; third, GPON can well support the management of end to end is also very important factors.
In addition, GPON and a full-service broadband characteristics of support, GPON can support mobile backhaul. bundled in the deployment of operators to do some time or a new point of deployment, in some cases can be used to support GPON mobile base station backhaul. GPON to support higher bandwidth, better device management, which in turn will bring relatively smooth operator support the development of higher bandwidth, the ability of the business.
who cost more economical?
economic benefits for operators are very concerned about the issue. There are many factors affecting the cost, such as: technical complexity, scale of production, and size of market applications.
EPON to provide added functionality, which makes traditional Ethernet chip makers can be easily EPON chip design. Currently the third generation EPON chip prices are not higher than the previous two generations of chip prices (and even decline), functional has continued to increase.
view of the high cost for GPON, often just that, with the expansion of application, GPON is constantly reducing the cost. . We see that global operators basically a different form of promotion or the construction of FTTx. Meanwhile, GPON as an international standard, it is supported by the number of firms is very large. from an operator perspective, considering GPON, or is already deployed GPON operators, is also a certain amount. in the GPON standards, the standardization progress is quite fast, all vendors are preparing to introduce the next generation of GPON products. With the application of increase, GPON cost reduction has been an inevitable trend.
