新一代光传输平台的建设——光预失真技术的应用

Building NG Fiber-Optical Transmission Platform

有线系统运营商和设备制造商正在寻找高性价比的升级途径,以增加用于数字业务的双向网络带宽。更多节点分割的光纤到户HFC架构是最主要的选择。运用具有专利技术——光预失真技术开发出来的光传输设备,既满足了运营商扩展容量的需求,又保证了系统端到端的性能,并使运营商整个网络的升级和改造成本大幅下降。LighwaveSolutions(LS)这种专有的在光域内进行线性化校正和主动反馈监测的技术使激光模块具有高失真抑制性和无可匹敌的温度性能,可满足CATV网络的高线性化和链路指标持续的一致性。

CATV network operators need to choose a method to determine the node size to get an adequate capacity of two-way network, when providing more and more users new digital services. The fiber-optical transmission equipment developed by using proprietary optical prc-distortion technology both meets operators' needs in expanding capacity and ensures system end to end performance. It also greatly reduces the cost of upgrading the network. The optical pne-distortion technology and optical transmitter module designed by adopting this technology is a reliable and economical choice for CATV operator. Radio & TV Broadcast Engineer-ing(RTBE) is a technical journal supervised by the State Administration of Radio, Film & TV (SARFT), P.R. China, sponsored by the Academy of Broadcasting Planning(ABP), SARFT, and published by the Institute of Information Research, ABP. Founded in 1974, the journal has become one of the most popular magazines in China. RTBE has a circulation of more than 30000 copies in China and overseas.
