The Huawei OSN9800 TNU3N402 single board belongs to the OTN line class of single boards, which realizes the interconversion of the following signals: 160 x ODU0/80 x ODU1/20 x ODU2/20 x ODU2e/4 x ODU3/2 x ODU4/160 x ODUflex2 x OTU4. OTU4 is a DWDM standard wavelength in compliance with the ITU-T G.694.1 recommendation. DWDM standard wavelength. The same optical port supports mixed transmission of ODU0, ODU1, ODU2/ODU2e, ODU3, ODUflex.N402 adopts coherent reception technology and is applied in coherent systems.
OSN9800 TNU3N402T61 Single Board Functions and Features (Line Mode)
| Functions and Features | Description | |||||
|---|---|---|---|---|---|---|
| Basic Functions |
Realizes interconversion of the following signals: 160 x ODU0/80 x ODU1/20 x ODU2/20 x ODU2e/4 x ODU3/2 x ODU4/160 x ODUflex2 x OTU4 Mixed transmission of ODU0, ODU1, ODU2, ODU2e, ODU3, ODUflex is supported on the same optical port. |
|||||
| Crossover Capability |
Support to realize service scheduling with crossover boards. 160 x ODU0/80 x ODU1/20 x ODU2/20 x ODU2e/4 x ODU3/2 x ODU4/160 x ODUflex |

| OTN Functions |
|
|||||
| WDM Specifications |
Supports ITU-T G.694.1 specifications for DWDM. |
|||||
| Wavelength Tunable Function |
Supports wavelength tunable optical modules. If the wavelength tunable optical module is configured, it can realize that the WDM side optical signal can be tunable in the 80-wave range in the 50 GHz interval of C-band. TNU5N402 Extended C-band 50 GHz interval is adjustable within 96 waves. |
|||||
| ESC Function | Support | |||||
| PRBS Function |
The PRBS function is supported on the WDM side. |
|||||
| Error Correction Coding |
Description:
Veneers with different error correction codes cannot be docked. |
|||||
| Performance Surveillance and Alarm Monitoring |
|
|||||
| Relay board |
The WDM side signal of N402 board can be relayed by other N401, N402, LTX, NS4 boards of the same FEC type. For example:
|
|||||
| Delay Measurement |
The single board supports delay measurement in the direction of the optical port (uplink direction) on the WDM side. When the single board builds an ODU4 high-order crossover, it supports high order ODU4 channel TCM delay measurement; when it builds a low order ODUk crossover, it supports high order ODU4 channel PM/TCM and low order ODUk channel TCM delay measurement. Description:
TNU1N402TNV1N402TNU2N402TNV2N402 only supports high-order ODU4 channel delay measurement. |

| Test Frame Function | Not supported | |||||
| IEEE 1588v2 | Not Supported | |||||
| Physical Layer Clock |
Description:
The physical layer clock is not supported when the single board is used with TNU2CTU. |
|||||
| Electrical Layer ASON | Supports | |||||
| Optical layer ASON | Support | |||||
| Protection Mode. |
Description:
Branch SNCP protection is not supported when the scheduling granule is ODUflex. The TNU5N402 does not support port-level M:N protection on the 9800 M24 subrack. The TNU5N402 veneer does not support port-level M:N protection when paired with the TNU2CTU. |
