China Unicom taps Coriant for 100G backbone upgrade

Optical transport vendor Coriant GmbH has notched another win with China Unicom to expand the operator's 100G backbone network linking the cities of Wuhan, Hefei, and Nanjing. China Unicom will deploy the Coriant hiT 7300 multi-haul transport platform as part of the fiber-optic network expansion.

"We're constantly working to accelerate the expansion of our mobile communications network across China, while providing our customers with high-quality broadband communications and information services," said Guangquan Wang, director of network technology, Network Technology Research Institute, China Unicom. "For this network expansion, we chose the Coriant hiT 7300 solution because it enables us to support an upgrade without interrupting existing traffic. It also provides us with the flexibility to add capacity as network demands increase."

Coriant says its hiT 7300 optical transport platform provides the China Unicom network with higher capacity, support for photonic mesh configurations, and scalability from 40G to 100G and beyond.

Coriant's optical transport team has been working with China Unicom since 2006 (see, for example, "China Unicom selects Nokia Siemens Networks to deploy optical network").
