Optoplex集成的 40-Gb/s DP-QPSK 接收機主要由一個90度的光學混頻器和4對平衡PD以及4個線性的TIAs組成。不像其他技術不包括內置偏振分束器(PBS)和功率分配器(BS)，Optoplex集成接收機其中包括了光學混頻器，PDs,TIAs提供了一個完全集成的解決方案,有利于用戶完全消除光纖路由選擇和偏離的管理。Optoplex的集成接收機工作速率可以支持12.8 gbaud / s以上。
Optoplex集成40 gb / s的DP-QPSK相干接收機的機械封裝，電氣接口和直流Pin的分配，是完全兼容OIF(IA)關于集成 Intradyne 100 - gb / s相干接收機執行協議(OIF2009.033.05)的。機械尺寸是50´27´7.5毫米。高速電氣接口(射頻輸出)使用OIF IA提議的共平面波導(CPW)。低速電接口(直流控制Pin)使用40Pin與OIF2009.033.05 IA中規定的一樣
