China Unicom to deploy 5,000km optical network in China

07 July 2011 |


China Unicom has announced that Nokia Siemens Networks (NSN) will be deploying a 5,000km fibre-optic network capable of 40Gbps per channel.

The network will cover seven provinces: Chongqing, Hubei, Anhui, Jiangsu, Fujian, Guangdong and Guangxi. It will also pave the way for future upgrades to 100Gbps technology, as China Unicom prepares for the anticipated growth in IP traffic.

A Point Topic report on VoIP highlighted the massive potential for growth which China is facing. It found that only one in 20 broadband subscriptions in China contained a VoIP bundle, as opposed to one in three in the US. It’s no surprise that Chinese carriers are making huge investments into their infrastructure.

“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,” said Markus Borchert, head of greater China region at NSN.

Borchert claimed that the system will use CP-QPSK technology for the first time in China, stating that this is “a new benchmark for enhancing transport performance and end-user experience”.

This is not the first time China Unicom has deployed NSN technology. In August 2010, it implemented NSN’s real-time traffic monitoring and analysis tool to increase 3G service quality.

It has been a busy week all round for developments in China. Within the last few days, China Telecom has signed a contract with Alcatel-Lucent Shanghai Bell (see more), to introduce what it describes as “blazingly fast” broadband services.
