DPSK解調器基于光纖延遲線干涉原理，實現由相位調制到幅度調制的變換,支持2.5G, 10G, 40G光纖傳輸速率，覆蓋C和L band，適用于光通信，軍事和航天探測等應用。DPSK解調器基于其free－space的技術，小尺寸，不需加熱，不依賴于偏振模式的特點。
主要特點：
Colorless 應用
緊湊型小尺寸
無源
FSR可定制 (12.5, 25, 40, 50, 66GHz)
高FSR精度 (<7 MHz for 50GHz)
1 ps 延時精度
消光比: >20 dB
極低的PDFS和TDFS (polarization phase shift <3o)
極低的插損以及PDL
易于和光電二極管集成
