OSN3500 SLQ1A optical interface boards are line single boards with 4 pairs of service access ports, and there is only one hardware version of the board, N1. The board is fully compatible with previous versions of the same model, and N1SLQ1 and N1SLQ1A can be used interchangeably. The N1SLQ1 and N1SLQ1A can be used in place of each other. The single board realizes the reception and transmission of STM-1 optical signals on OSN3500 transmission equipment. The received optical signals are sent to the cross side after O/E conversion, while the electrical signals on the cross side are sent out after E/O conversion. The single board does not support two-fiber bidirectional multiplexing segment protection networking. The indicators on the panel of the single board are: single board hardware status lamp (STAT) - red and green two-color indicator, service activation status lamp (ACT) - green indicator, single board software status lamp (PROG) - red and green two-color indicator, service warning indicator, (SRV) -Red, green, and yellow indicator lights,
