基于CWDM的波长转换器模块化设计

Modular design of optical transport unit based on CWDM

在研究粗波分复用(CWDM)技术和波长转换技术的基础上,设计了一个适用于CWDM系统的波长转换器模块。该模块支持8个CWDM信道,可工作于多速率状态。模块除内部具有3R功能还具有激光器偏流指示、发送功率指示、激光器关断控制、接收功率指示、低输入功率告警指示和速率选择等功能。实验结果表明,该模块较好地实现了波长的转换,具有较高的稳定度和实用性。

Based on the study of CWDM and wavelength conversion technology, OTU module applicable to CWDM system is designed. The module supports an eight-channel of CWDM and works in a state of multi-rate. The module has 3R function to ensure the quality of the signal conversion, and high speed data and clock signal are output and can be used as performance monitoring. Experimental results show that the module successfully realizes the conversion of wavelength with better stability and practicability.
