本文实验研究了高速通道密集型波分复用传输系统.在40km色散位移光纤上成功地实现了10Gb/s 4通道(总容量达 40Gb/s)波分复用光传输.该系统发送端采用混合集成分布反馈激光器(DFB—LD)/驱动器组件,收端采用两个级联半导体光放大器组件.实验确信由于 SOA(半导体光放大器)本身具有的宽带特性适合于高比特率的WDM(波分复用)传输系统.采用强度调制直接检测法(IM/DD)实现的40Gb/s的传输容量是目前报道的最大容量,该技术使得将来的超大容量(达几百Gb/s)长距离传输系统成为可能.
In this paper, a high speed channel dense wavelength division multiplexing transmission system is experimentally studied, and a 10Gb / s 4 channel (total capacity 40 Wb / s) wavelength division multiplexing optical transmission is successfully implemented on a 40 km dispersion-shifted optical fiber. (DFB-LD) / driver components, two cascaded semiconductor optical amplifier components are used at the close end.Experiment convinced that due to the wideband nature of SOA (Semiconductor Optical Amplifier) itself, it is suitable for high bit rate WDM Multiplexing) transmission system. The 40Gb / s transmission capacity achieved with IM / DD is currently reported as the maximum capacity currently reported, enabling future transmission of very large capacity (up to hundreds of Gb / s) over long distances System becomes possible.
