SDH光接收模块具有高速高增益的特点，电路板设计的好坏是模块的性能指标能否实现的关键环节之一。为此，本文结合光接收模块的制作，从多个方面对高速板设计技术进行了详细的分析。并在充分运用高速板设计方法的基础上研制出高灵敏度小型化SDH光接收模块。
SDH optical receiver module with high-speed high-gain characteristics of the circuit board design is one of the key aspects of the module’s performance can be achieved. For this reason, this text has carried on the detailed analysis to the design technology of the high-speed board from many aspects with the fabrication of the light-receiving module. And make full use of high-speed board design method based on the development of high sensitivity miniaturized SDH optical receiver module.
