富光科技 CWDM 4 Rx TFF 一体化集成光组件基于 Fiber-to-the-Chip (FTTC) on-board connectivity technolog从光纤到芯片的板上连接技术，应用于400G及更高速率光模块的接收端，起分波作用，它由Receptacle链接头、迷你准直器、CWDM 4 Z-block、透镜阵列和输出棱镜等经过高精度pitch定位组装而成。
通过对有限空间范围内光路设计优化和光学元件的优化，极大降低了器件功耗和单位比特的成本，与基于AWG技术的DEMUX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。
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，同时也接受客户对生产线进行现场稽核，按需提供产品底层数据和半成品相关性能指标数据。。
