3 EPONGPON Overview.ppt

* * * * * * Fiberhome Proprietary and Confidential * NTT View of EPON “Two types of giga-bit PON systems have been standardized: G-PON by ITU-T and GE-PON by IEEE. Now the question is which one is more promising? ... In Japan, we have seen a drastic price reduction of media converters which could be realized by sharing the technology and products of the LAN market. For services, high quality IP Telephone and IP video are becoming critical basic FTTH services. And for the core network, in NTT we have a full IP backbone network for the FLET’s service. Switches and routers in the network employ Ethernet interfaces. Given these factors, we decided to develop GE-PON as the next-generation FTTH system.” ----Hiromichi Shinohara, Director of NTT Access Labs (IEEE Communications Magazine, September 2005) * Fiberhome Proprietary and Confidential * Outline EPON vs. GPON CTC EPON IOP Summary * Fiberhome Proprietary and Confidential * Summary EPON is more mature cost-effective than GPON. Both GPON EPON will coexist in a long time. Fiberhome is a FTTH leader in China. With our effort, Fiberhome FTTH system will be deployed worldwide soon. * Fiberhome Proprietary and Confidential * Thank you for attention! * * * * * * * * * * * * * * * * * * * * * * * * * * * * Fiberhome Proprietary and Confidential Fiberhome Proprietary and Confidential * Fiberhome Proprietary and Confidential Insight into EPON GPON Sept. 1st, 2007 * Fiberhome Proprietary and Confidential * Outline EPON vs. GPON CTC EPON IOP Summary * Fiberhome Proprietary and Confidential * EPON Vs.
