ZTE set to complete massive optical transmission network
November 21, 2005 Shenzhen, China -- One of the world's largest optical transmission networks is to be completed in China following an agreement for its second construction phase between ZTE, a global provider of telecommunications equipment and networking platforms, and China Mobile, that nation's largest mobile operator. The approximately 25,000-km network, set for completion by March 2006, will include 521 network nodes covering 18 provinces in western and southern China.
November 21, 2005 Shenzhen, China -- One of the world's largest optical transmission networks is to be completed in China following an agreement for its second construction phase between ZTE, a global provider of telecommunications equipment and networking platforms, and China Mobile, that nation's largest mobile operator. The approximately 25,000-km network, set for completion by March 2006, will include 521 network nodes covering 18 provinces in western and southern China.
The network is based on ZTE's ZXWM M900 DWDM technology, which incorporates ultra long-haul transmission technologies including ERZ (Enhanced Return to Zero code) modulation, AFEC (Advanced Forward Error Correction), HOBA (High-power Optical Booster Amplifier), and compensation technologies.
"The network has been built in two phases," explains Mr. Shen Li, ZTE's general director for China Mobile. "Phase 1 has been serving 17 provinces, mainly in western and southern China, since its operation in 2002. Phase 2 is an independent network that will overlap with Phase 1, covering 13 provinces of the same region. The networks will improve transmission quality and meet the increasing demand in these regions for bandwidth, especially for data and multimedia services."
The announcement marks the latest DWDM contract win for ZTE, which says it has now installed 150,000 sets of optical products in over 40 countries and regions, providing DWDM networks in countries including India, Indonesia, Pakistan, and Bulgaria.
"Long-haul transmission technologies can address the transmission problems of long-haul multiplexing and decrease OTM (Optical Terminal Multiplexing) network nodes, thereby lowering construction costs and increasing China Mobile's competitiveness," continues Li.
"We are confident of ZTE's ZXWM M900 DWDM equipment, which features powerful capacity, full service access, and smooth scalability," concludes Mrs. Wei Lihong, network division director at China Mobile.
