5000 kilometer information super-highway for China
Beijing, China – ---
Nokia Siemens Networks to deploy optical network for China Unicom
China Unicom subscribers can look forward to a ten-fold increase in their access data rates thanks to a faster information highway across the country. Nokia Siemens Networks is deploying a 5000 kilometer, 40 Gigabits per second, per channel, dense wavelength division multiplexing (DWDM) optical network for the operator. The technology paves the way for upgrades to 100Gbps across seven provinces: Chongqing, Hubei, Anhui, Jiangsu, Fujian, Guangdong and Guangxi.
The increased uptake of bandwidth-hungry applications requires capacity upgrades in the backbones of China Unicom’s networks to maximize subscriber experience. Nokia Siemens Networks’ DWDM network will prepare the operator to handle future IP traffic growth while reducing the number of sites and keeping control of its costs.
“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.”
Nokia Siemens Networks is providing its hiT 7300 DWDM system with industry leading 40G transponder technology that allows continued use of installed fiber infrastructure. Based on CP-QPSK modulation format, hiT 7300 DWDM system with dispersion compensating modules free transmission*, enables lower latency and offers a rapid, cost effective transition to 100G technology. Moreover, Nokia Siemens Networks will provide its network management system coupled with services such as network implementation, commissioning and maintenance.

* CP-QPSK (coherent polarization multiplexed quadrature phase shift keying) is a modulation format that uses coherent transmission technology. In new deployments, operators can even avoid the need for dispersion compensating modules (DCM), leading to low-latency connections, simplified amplifier design coupled with overall reduction in deployment costs and footprint. Moreover, it reduces the operating expenditure and speeds up service delivery. In the existing networks, it utilizes the installed network infrastructure, thereby, protecting operators’ capital investments.
Nokia Siemens Networks’ DWDM (Dense Wave Division Multiplexing) solution, comprising of the hiT 7300 and TransNet DWDM planning and automation tool, provides a cost optimized, flexible and automated platform, thereby, offering a viable answer to excessive traffic demand, reconfiguration and cost pressure issues. The design principle of the DWDM platform (hiT 7300) is based on high modularity as well as high re-use, thus, creating a single platform from metro to core. It also provides network operators with a new level of simplicity for commissioning and maintaining DWDM systems, driving out complexity while providing complete administrator control. Nokia Siemens Networks’ TransNet end-to-end planning tool provides optimal network design, guaranteed performance and automated configuration, resulting in significant OPEX savings. It also reduces outage time and procedural errors along with an exceptionally low TCO.
Nokia Siemens Networks provides a migration path to Terabit Optical Transport with over 115 DWDM customers around the world, It also provides scaling capacity for channels of 10/40/100 Gbit/s with its platform being open to 400Gbit/s and even more. Nokia Siemens Networks has 12 hiT 7500 customers and 103 hiT 7300.
