TNZ8NQ2 overview

TNZ8NQ2 is a 4*port 10G line service processing board applied to Huawei OSN 1800 II Enhanced, OSN 1800V.

The TNZ8NQ2 board is a line board that supports hybrid transmission of OTN services (ODU0/ODU1/ODU2/ODU2e/ODUflex) and packet data packets with a maximum bandwidth of 40 Gbit/s.

It also supports transmission of one or two types of services.

The TNZ8NQ2 board processes and converts the received service signals into four OTU2/OTU2e signals, which are carried over ITU-T G.694.1-compliant DWDM wavelengths.

Basic functions

Cross-connect functionality

Implements service grooming when working with cross-connect boards.

32 x ODU0/16 x ODU1/32 x ODUflex/4 x ODU2/4 x ODU2e

Wavelength division multiplexing (WDM) specifications

Supports ITU-T G.694.1-compliant dense wavelength division multiplexing (DWDM) specifications.

Port specifications

Tunable wavelengths

Supports optical tunable transponders. NQ2 boards equipped with optical tunable transponders can tune optical signals output on the WDM side within the range of 80 wavelengths in C-band with the channel spacing of 50 GHz.

Protection schemes

Intra-Board 1+1 Protection



Supported (k = 0, 1, 2, or flex)

Tributary SNCP


Overtemperature protection

If the working temperature of the board exceeds the configured threshold and services are affected, the board will automatically reset the key chip to prevent damages to the board.

Automatic laser shutdown (ALS)

Not supported

Physical Clocks

Supported (ODU0, ODU1, ODUflex)

IEEE 1588v2

Not supported

Maintenance features


  • Supports system-side channel inloops and outloops.
  • Supports WDM-side inloops and outloops. (This function has no impact on overheads and the PRBS function.)

Pseudo random binary sequence (PRBS) test function


Test frames

Not supported

Delay measurement (DM)


Alarms and performance events monitoring

  • Monitors parameters such as the bias current, operating temperature, and optical power of a laser.
  • Monitors OTN alarms and performance events.
  • Monitors bit interleaved parity 8 (BIP8) bytes (Bursty mode) to help locate line failures.

OTN overheads

Adopts the ITU-T G.709-compliant frame format and overhead processing.

  • Provides path monitoring (PM) for ODU2, ODUflex, ODU1, and ODU0.
  • Provides section monitoring (SM) for OTU2.
  • Provides tandem connection monitoring (TCM) for ODU2, ODU1, and ODU0.

Outband DCN

Supports ESC communication.


General communication channels (GCCs) support 3-byte and 18-byte modes.

FEC mode

  • Supports ITU-T G.709-compliant forward error correction (FEC) encoding.
  • Supports ITU-T G.975.1-compliant advanced forward error correction (AFEC)-2 encoding.


Boards adopting different error correction encoding modes cannot interoperate with each other.

Electrical-layer ASON



This feature is supported only when the equipped system control board is TNZ5UXCMS/TNZ8XCH.
