Product Code TN55NS3T01 TN58NS4T51 TN58NS4T61 Part Number 03030NCN-001 03031EQH 03031GGX Description 40Gbit/s Line Service Processing Board(ULH,HFEC, Coherent,Tunable,50GHz,LC) 100Gbit/s Line Service Processing Board(SLH,SDFEC2, Coherent,Tunable,50GHz,LC) 100Gbit/s Line Service Processing Board(ULH,SDFEC2,wDCM, Coherent,Tunable,50GHz,LC) Huawei TN58NS4T51 Board realizes the relay of one optical signal, and transmits and receives OTU4 optical signals whose wavelengths at both ends comply with the DWDM standard wavelength recommended by ITU-T G.694.1. The optical receiving module receives the optical signal to be relayed by “IN”. The optical port completes the O/E conversion. The electrical relay module performs signal decoding, overhead processing, and encoding. In this process, the electrical signal-based shaping, regeneration, and retiming are completed and packaged into the OTN frame signal format. The encoded signal is sent to the optical transmission module, and after E/O conversion, it transmits an OTU4 optical signal that conforms to the DWDM standard wavelength recommended by ITU-T G.694.1. The converted optical signal is output from the “OUT” optical port. In OptiX OSN 8800 T64 enhanced subrack/OptiX OSN 8800 T32 enhanced subrack/OptiX OSN 8800 T16 subrack. Huawei TN58NS4T51 Board supports line mode and trunk mode. When working in line mode, the OptiX OSN 8800 T64 enhanced subrack must be configured with USXH+UXCT boards, the OptiX OSN 8800 T32 enhanced subrack must be configured with UXCH/UXCM boards, the OptiX OSN 8800 T16 subrack must be configured with TN1 6UXCM boards.
