The main function of Huawei OSN3500 N1SLT1 is to receive and transmit 12-channel STM-1 optical signals. In the sending direction, it converts the received electrical signals into SDH optical signals and sends them to the optical fiber for transmission. In the receiving direction, converts the received optical signals into electrical signals. Detects the R_LOS alarm signal and provides laser shutdown. The optical interface provides laser on and off settings and laser auto shutdown function. Support single-fiber bi-directional optical modules, single-fiber bi-directional optical modules do not support the use of pigtails for optical interface loopback. Holds 1 to 12-way ECC communication. The first eight optical ports support ECC communication in D1 to D12 channel mode, and the last four optical ports support ECC communication in D1 to D3 channel mode. Support FPGA online loading function. Support smooth upgrade of single board software. Support PRBS function. Support clock synchronization feature and segment overhead byte transmission time information.
When the cross OSN3500 SDH Optical Transmitter transmission equipment fork capacity is 200Gbit/s, slots 1 to 4 and 15 to 16 can be configured with 1 to 8 optical ports, and slots 5 to 8 and 11 to 14 can be configured with 1 to 12 optical ports.
