中国联通将在其北京总部和广东、福建、浙江三省部署由北电网络提供设备的长途光传输骨干网络,合同总值达1400万美元。据悉,北电OPTera 1600长途光纤系统使用密集波分复用(DWDM)技术,可将光分解为高达160个频道,以最大限度实现每条光纤的容量,支持因特网的骨干网传输更多的数据,而DWDM则支持多个太比特的高带宽拉入器和电子电路系统。 China Unicom will deploy a long-distance optical transport backbone network of equipment provided by Nortel Networks in its Beijing headquarters and three provinces of Guangdong, Fujian and Zhejiang provinces, with a total contract value of US $ 14 million. It is reported that Nortel OPTera 1600 long-distance optical fiber system using Dense Wavelength Division Multiplexing (DWDM) technology, the light can be decomposed into up to 160 channels to maximize the capacity of each fiber to support the Internet backbone to transmit more data , While DWDM supports multiple terabit high-bandwidth drawers and electronic circuitry.
