A wavelength adapter used for broad-band MAN

提出了一种由光收发器、时钟数据再生电路、8×8交叉矩阵、控制单元及性能单元组成的波长适配器(WLA),并对本方案所提出的WLA建立了单元测试和简单光传输测试系统实验平台。实验结果表明,该WLA支持同步数字体系(SDH)和千兆以太网(GE)等多种速率光信号的波长转换,各项指标均优于波长转换器的光接口参数的规范要求。

A wavelength adapter （WLA） is composed by the optical transceiver, clock and data regeneration circuit, a performance monitoring of 8 × 8 matrix, control unit and the performance of the modules is proposed in this paper. And a unit testing and simple optical transmission system test experimental platform is established. The results show that the WLA in this paper supports synchronous digital hierarchy （SDH） and gigabit Ethemet （GE）, and other multi-rate optical signal wavelength conversion. And the indicators are better than the optical wavelength converter parameters of the interface specifications.
