Huawei OSN3500 SSN1SEP1 is an 8-channel STM-1 line processing board but the SEP1 optical interface board belongs to the line single board, which realizes STM-1 optical/electrical signal reception and transmission on the device. Through this single board, SEP1 sends the received optical signals to the crossover side after O/E conversion, or sends the received electrical signals directly to the crossover side, and at the same time sends the electrical signals from the crossover side after E/O conversion. The single board completes the processing of STM-1 signals. When SEP1 adopts panel out (the network management display logic single board is SEP1), it completes the processing of 2-channel STM-1 electrical signals; when the SEP1 board cooperates with the junction board (the network management display logic single board is SEP), it completes the processing of 8-channel STM-1 optical/electrical signals or the processing of 4-channel STM-1 electrical signals. The physical single board of both is SEP1, collectively referred to as SEP1 when no distinction is made between logical single boards.
