这款8芯的5G Massive MIMO Armored Optical OM3 Fiber CPRI Cable 基站跳线两端预端机双工的LC头，用于5G基站AAU到DU的传输。AAU DU侧都含有4个25G SFP28的光模块，发射和接收总共8路。

AAU is Active Antenna Unit, using Massive MIMO technology to improve the signals covering for high frequency.

DU is Distribute Unit. The transmission between AAU to DU is fronthaul.

CU is Centralized Unit. The transmission between DU to CU is midhaul.
