摘要
光纤通信网络已进入速率超100 Gbit/s时代,并向400 Gbit/s/1 Tbit/s迅速发展。目前在400 Gbit/s/1 Tbit/s速率以上的多数试验中,高速OOFDM(光正交频分复用)可行的传输方案有COOFDM(相干探测光OFDM)、AOOFDM(全光OFDM)和混合型电光OFDM三种系统。文章对比分析了三种高速OOFDM系统发射端和接收端结构,综述了三种系统在高速光纤传输中的性能优缺点以及下一步研究的重点。
Abstract
Fiber optic communication network has stepped into a new era of 100 Gbit/s (or above) systems and strides rapidly toward the rate of 400 Gbit/s/1 Tbit/s systems. Currently, in most 400 Gbit/s/1 Tbit/s tests, the feasible Optical OFDM (OOFDM)based highrate transmission schemes include the Coherent Optical OFDM (COOFDM), AllOptical OFDM (AOOFDM) and hybrid electrooptical OFDM. This paper comparatively analyzes the transmitter and receiver structures of the above mentioned three types of systems and summarizes their performance advantages and disadvantages in highrate fiberoptic transmissions and the focal point in the next step researches.
