China Unicom Deploy 40 Gbps Optical Backbone with NSN

China Unicom is upgrading its optical backbone with Nokia Siemens Networks' 40 Gbps optical transmission platform.


The 5000 kilometer, 40 Gbps DWDM network paves the way for upgrades to 100Gbps across seven provinces: Chongqing, Hubei, Anhui, Jiangsu, Fujian, Guangdong and Guangxi.


Specifically, Nokia Siemens Networks is providing its hiT 7300 DWDM system with 40G transponder technology that allows continued use of installed fiber infrastructure. The system leverages CP-QPSK modulation with dispersion compensating modules free transmission. Moreover, Nokia Siemens Networks will provide its network management system coupled with services such as network implementation, commissioning and maintenance.


"As one of the largest network operators globally, China Unicom understands the importance of investing in the latest technology," said Markus Borchert, head of Greater China region at Nokia Siemens Networks. "Our 40G DWDM system will ensure a longer life cycle for China Unicom's network by increasing its network capacity to handle data traffic growth. In fact, since CP-QPSK* technology is being used for the first time in China, it will act as a new benchmark for enhancing transport performance and end-user experience." http://www.nsn.com
