富光科技 0.75 pitch CWDM 4 Rx TFF 一体化光组件是利用富光科技自由空间微光学波分复用设计和制造平台推出的起到Demux功能的0.75 pitch ROSA集成光组件，它基于 Fiber-to-the-Chip (FTTC) on-board connectivity technolog从光纤到芯片的板上连接技术，把Receptacle同轴陶瓷插芯链接头、小型准直器、CWDM 4 Rx Z-block、透镜阵列和输出棱镜等光学元件经过光耦合和高精度定位集成在一起，实现与客户Com端光口插拔对接，与客户PD端电口无缝耦合对位
与基于AWG技术的Rx组件相比较，它具有更低插损、更高隔离度、更优通道一致性和更高热稳定性的特点。
富光科技为客户提供从滤波片开炉到产品设计、光路仿真、可靠性分析和系统容差评价的深度定制服务，成品提供PD光电流数据。
