大容量副载波复用光纤传输技术

Great Capacity SCM Optical Fiber Transmission System

本文分析、讨论了光纤副载波多路复用(SCM)传输系统中副载波频率配置的原理。根据传输容量的大小和光器件技术参数,以产生二阶互调干扰最小为准,提出了几种副载频率配置的方法,它适用超宽频带中SCM系统的设计,并能用来估算在光器件调制频宽内SCM系统应用的潜力。

This paper discusses the principle of subcarrier frequencydisposition in subcarrier multiplexed(SCM) systems. According totransmission capacity of SCM systems and parameters of lightwavecomponents several methods to generate second order intermodulationproducts with minimum interference are offered. These methods aresuitable for the design of superbroad bandwidth SCM systems and theestimation of the relevant potentiality.
