1、前言
光模块由光电子器件、功能电路和光接口等组成，光电子器件包括发射和接收两部分。光模块的作用就是光电转换，发送端把电信号转换成光信号，通过光纤传送后，接收端再把光信号转换成电信号。以光器件为核心增加一些电路部分和结构件等完成相应功能的单元。
2、方案概述
Ameya360 光模块解决方案光器件是由少数几个光电子元件和 IC 、无源元件（如电阻、电容、电感、互感、微透镜、隔离器）、光纤及金属连线组合、封装在一起，完成单项或少数几项功能的混合集成件。光收发一体化模块主要功能是实现光电 / 电光变换，包括光功率控制、调制发送，信号探测、IV 转换以及限幅放大判决再生功能。DM 技术实现一根光纤传输双向信息号 (点到点的传输。尤其是光纤资源不足，需要 1 根光纤传双向信号)。GigacBiDi 包括 SFP 单纤双向（BiDi），GBIC 单纤双向（BiDi），SFP+ 单纤双向（BiDi），XFP 单纤双向（BiDi），SFF 单纤双向（BiDi）等等。
