Release Date：2009-05-18 Author：ZTE Click：
ZTE announced that China Telecom, the largest telecom carrier in China, achieved an industry breakthrough by deploying ZTE's Ethernet Passive Optical Networks (EPON) solution. By deploying the solution, China Telecom was able to successfully cutover between EPON technology that carries CDMA 1X services and EV-DO high-speed data services to implement the world's first EPON technology that offers 3G services.
The announcement is the culmination of the successful trial conducted by Shanghai Telecom, a subsidiary of China Telecom, in February 2009. Early in March 2009, the company finally completed the cutover of the CDMA 1X services and EV-DO high-speed data services over EPON and achieved on-site service test results with flying colors. During nearly one hour of continuous call testing, the voice services demonstrated good quality and stable signals, while the EV-DO data services smoothly and steadily play online videos. This only proves that EPON is an alternative technology platform to help operators offer 3G services.
ZTE's EPON solution helped Shanghai Telecom address transmission problem between its backend machine rooms and CDMA base stations located in remote facility. As a result, Shanghai Telecom is now able to provide its subscribers with excellent quality, high access speed along with rich, reliable and more convenient fixed CDMA convergence services. More importantly, Shanghai Telecom was able to reduce overall network construction cost―a key factor in launching its 3G services.
