The POB48 series parallel optical transceiver module is designed for defense communication command systems and subsystems, enabling bidirectional conversion between multi-channel electrical and optical signals. The module adopts a hermetically sealed micro-socket package structure, featuring a spring-loaded crimp-style electrical connector and a 48-core MT/MPO optical interface. It operates within a case temperature range of -40°C to +85°C, supporting single-channel transmission rates from 1.25 Gbps to 10.3125 Gbps.
