Huawei OSN3500 SSN4SL64 optical interface boards belong to line single boards, realizing the reception and transmission of STM-64 optical signals.The N1SL64/N4SL64 support the single board compatible substitution function; they do not support the TCM function and the AU-3 service.The N2SL64 does not support the single board compatible substitution function; they support the TCM function and the AU-3 service, but they cannot be enabled at the same time. N4SL64 supports standard optical interfaces of I-64.1, S-64.2b, Le-64.2, P1L1-2D2, and V-64.2b (plus BA, PA, and DCU).I-64.1, S-64.2b, Le-64.2, and V-64.2b optical interface features,P1L1-2D2 optical interface features.N4SL64 supports CWDM and N4SL64 supports CWDM and DWDM color optical interfaces, and the optical interface adopts LC connector; CWDM optical interface supports 70km transmission distance, and DWDM optical interface supports 40km and 80km transmission distance. Support two-fiber multiplexing segment ring protection. Supports quad-fiber multiplexing segment ring protection. Supports linear multiplexing segment protection. Supports SNCP protection. Supports SNCMP protection. Supports SNCTP protection. Supports shared fiber virtual path protection. Supports shared fiber path protection for multiplexed segments. Provides 2 sets of Kbyte processing capacity, and 1 SL64 board supports up to 2 MSP loops.N1SL64/N4SL64 supports VC-4 level inner loopback and outer loopback. Support query function of single board manufacturing information. Support FPGA online loading function.
