富光科技 0.75 pitch CWDM 4 Rx TFF 一體化光組件是利用富光科技自由空間微光學波分復用設計和制造平臺推出的起到Demux功能的0.75 pitch ROSA集成光組件，它基于 Fiber-to-the-Chip (FTTC) on-board connectivity technolog從光纖到芯片的板上連接技術，把Receptacle同軸陶瓷插芯鏈接頭、小型準直器、CWDM 4 Rx Z-block、透鏡陣列和輸出棱鏡等光學元件經過光耦合和高精度定位集成在一起，實現與客戶Com端光口插拔對接，與客戶PD端電口無縫耦合對位
與基于AWG技術的Rx組件相比較，它具有更低插損、更高隔離度、更優通道一致性和更高熱穩定性的特點。
富光科技為客戶提供從濾波片開爐到產品設計、光路仿真、可靠性分析和系統容差評價的深度定制服務，成品提供PD光電流數據。
