100Gbit/s tunable wavelength WDM line service processing board, apply to Huawei OSN8800.

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, TN54NS4T01 can work only in relay mode.

When TN54NS4T01 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.

TN54NS4 can be substituted by TN56NS4/TN57NS4 on the NMS without any software upgrade.

Boards that use different FEC modes cannot interconnect with each other.

TN54NS4T01 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.

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 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.


TN54NS4T01 is a 100G OTN line board (40000 ps/nm,LH,HFEC,Coherent Tunable,50GHz,LC), converts 80*ODU0, 80*ODUflex, 40*ODU1, 10*ODU2, 10*ODU2e, 2*ODU3, 1*ODU4 into one OTU4 signal. TN54NS4T01 can apply to Huawei OSN8800. In general OSN 8800 T64/T32 subrack and OSN 8800 universal platform subrack, TN54NS4T01 can work only in relay mode; If you need TN54NS4T01 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.

TN54NS4T01 part number is 03030PGT, some other version like TN56, TN57 and TN58 with different system compatibility and feature supported. TN56NS4/TN57NS4 can substitute for TN54NS4 on the NMS without any software upgrade.

Q: How many hardware version does NS4 have?

A: NS4 is available in TN54, TN56, and TN57. The mappings between the board and equipment are as below:

BoardInitial Versiona(a)General 8800 T64 SubrackEnhanced 8800 T64 SubrackGeneral 8800 T32 SubrackEnhanced 8800 T32 Subrack8800 T16 Subrack8800 Universal Platform Subrack6800 Subrack3800 Chassis
a: If there is a substitution relationship between two boards and one of the boards is used to replace the other board, the device initial version supported by the replaced board takes effect. For example, when you use TN56NS4T11 to replace TN54NS4T11, TN56NS4T11 can be supported by V100R007C00.

Q: What's the board substitution relation among different versions?


Original BoardSubstitute BoardSubstitution Rules
The TN56NS4/TN57NS4 can be created as 54NS4 or 54NS4(REG) on the NMS. The former can substitute for the latter, without any software upgrade. After substitution, the TN56NS4 functions as the TN54NS4.

Q: Can I return/exchange board if not compatible with my system?

A: Yes, please tell our sales team your system and main control board version, before purchase.

Q: The board is new or refurbished?

A: It is original new, not been used.

Q: What is the lead time for TN54NS4T01 board?

A: In normal condition is 5 days, better to confirm with our sales team before your purchase.
