摘要

针对高速率OTDM（光时分复用）系统中的一些关键技术问题

如时钟提取、时分解复用和色散补偿等

提出了8×40Gbit/s的OTDM系统技术方案。结果表明

通过选择合适的时钟提取方式和基于对称性色散位移光纤的色散补偿技术

能够实现在一个时隙内对每个信道的40 Gbit/s归零码信号的解复用

且解复用后的信号质量较好。该系统实现了320Gbit/s OTDM通信。

Abstract

For some key technological issues in high-rate Optical Time Division Multiplexing（OTDM）systems

such as clock extraction

time division demultiplexing and dispersion compensation

we present an 8×40Gbit/s OTDM system technological scheme.The results indicate that by choosing appropriate clock extraction and the symmetrical dispersion shifted fiber-based dispersion compensation technology

we can demultiplex the 40Gbit/s RZ signals in every channel in one timeslot

and with good quality at that.This system realizes 320Gbit/s OTDM communication.
