New Circuit to Better Link Beijing and Wuhan
China will import equipment worth 140 million yuan from Japan's NEC (Nippon Electric Corp) to build a new micro-wave telecommunications circuit linking Beijing and Wuhan, capital of Central China's Hubei Province, according to Wednesday's Chinadaily.
The contract of the project was signed yesterday in Beijing. National Power Telecommunications Center, a subsidiary of the State Power Corp of China, is the operator of the project.
After public bidding last year, the center chose NEC from seven competitors because of its advanced technology and low price, the paper cited director of the center Cao Youzhi as saying.
The 1,200-kilometer Beijing-Wuhan SDH (synchronized digital hierarchy) microwave circuit will go into trial operations by July2001. With 34 microwave stations, the circuit is capable of handling 310 megabits per second.
The new system will replace the current Beijing-Wuhan digital microwave circuit built 20 years ago.
The new SDH circuit will better cater to telecommunications demand related to the coming power transmission from the Three Gorges Hydropower Station, the paper said.
The Beijing-Wuhan SDH circuit is part of an ongoing plan launched by the State Power Corp of China to advance its national electric telecommunications system.
