100Gbit/s tunable wavelength WDM line service processing board, apply to Huawei OSN8800.
TN57NS4T65 applies to metro networks, and its WDM-side module requires use of the same wavelength at the transmit and receive ends and does not support wavelength change by configuring regeneration boards.
Available functional versions of the NS4 board are TN54, TN56, TN57 and TN58.
In general OSN8800 T64/T32 subrack and OSN 8800 universal platform subrack, TN57NS4T65 can work only in relay mode.
When TN57NS4T65 works in line mode, enhanced OSN 8800 T64 subrack must use TNK2USXH+TNK2UXCT; enhanced OSN 8800 T32 subrack must use the TN52UXCH/TN52UXCM; and OSN 8800 T16 subrack must use TN16UXCM.
TN57NS4 can be substituted by TN58NS4 on the NMS without any software upgrade.
Boards that use different FEC modes cannot interconnect with each other.
Achieves cross-connection at the electrical layer, and to provide OTN interfaces and ESC.
Supports OTU4 interface on the WDM side.
Supports OTN frame format and overhead processing by referring to the ITU-T G.709.
OTU4 layer: supports SM function.
ODUk (k=0, 1, 2, 3, 4, flex) layer: supports PM andTCM function; PM and TCM non-intrusive monitoring functions.
Tune optical signal output on WDM within range of 80 wavelengths in C-band with channel spacing of 50 GHz.
Supported ESC function.
Supports the PRBS function on the WDM side.
Supports HFEC and SDFEC on the WDM side.
The WDM-side signals from an NS4 board can be regenerated by another NS4 or an LTX of the same type.
Supports intra-board 1+1 protection (when working with the OLP/DCP/QCP board).
Supports tributary SNCP protection, ODUk SPRing protection and ODUk SNCP.
Supported WDM side and ODU0/ODU1/ODU2/ODU3/ODU4/ODUflex Channel Loopback.
TN57NS4T65 is a 100G OTN line board (12000 ps/nm,Tunable,ePDM,QPSK,SDFEC2,wDCM-Metro), converts 80*ODU0, 80*ODUflex, 40*ODU1, 10*ODU2, 10*ODU2e, 2*ODU3, 1*ODU4 into one OTU4 signal. TN57NS4T65 can apply to Huawei OSN8800. In general OSN 8800 T64/T32 subrack and OSN 8800 universal platform subrack, TN57NS4T65 can work only in relay mode; If you need TN57NS4T65 works in line mode, enhanced OSN 8800 T64 subrack must use TNK2USXH+TNK2UXCT, enhanced OSN 8800 T32 subrack must use the TN52UXCH/TN52UXCM and OSN 8800 T16 subrack must use TN16UXCM.
