China Telecom Uses EPON Backhaul for 3G Services

China Telecom has deployed ZTE's Ethernet Passive Optical Networks (EPON) solution to carry its CDMA 1X services and EVDO traffic.


The announcement is the culmination of the successful trial conducted by Shanghai Telecom, a subsidiary of China Telecom, in February 2009. Early last month, the company finally completed the cutover of the CDMA 1X service and EVDO high-speed data service over EPON and achieved on-site service test results with flying colors. During nearly one hour of continuous call testing, the voice service demonstrated good quality and stable signals, while the EVDO data service smoothly and steadily play online videos. This only proves that EPON is an alternative technology platform to help operators offer 3G services.


ZTE said its EPON helped Shanghai Telecom to provide transmission between its backend machine rooms and CDMA base stations located in a remote facility. Financial terms were not disclosed.


Apart from Shanghai Telecom, another leading operator in China, the China Mobile has adopted EPON technology to carry its GSM services. It has been providing the services for more than a year now in mainland China.
