TNZ8NQ2

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

ODUk SNCP

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

Tributary SNCP

Supported

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

Loopbacks

• 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

Supported

Test frames

Not supported

Delay measurement (DM)

Supported

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.

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.

Electrical-layer ASON

Supported
