TNZ8NS4

Basic functions

Supports conversion of the following signals:

80 x ODU0/80 x ODUflex/40 x ODU1/10 x ODU2/10 x ODU2e/2 x ODU3/1 x ODU4<->1 x OTU4

Supports hybrid transmission of ODU0, ODU1, ODU2, ODU2e, and ODUflex signals.

Cross-connect functionality

Implements the following service grooming when working with cross-connect boards: 80 x ODU0/ODUflex, 40 x ODU1, 10 x ODU2/ODU2e, 2 x ODU3, 1 x ODU4.

OTN function

• Supports OTU4 interfaces on the WDM side.
• Adopts the frame formats and overhead processing methods defined in ITU-T G.709.
• Supports the SM function at the OTU4 layer.
• Supports the PM and TCM functions at the ODUk (k = 0, 1, 2, 2e, 3, 4, or flex) layer, and non-intrusive monitoring of PM and TCM overheads.

WDM specifications

Supports ITU-T G.694.1-compliant DWDM specifications.

Tunable wavelengths

Tunes the optical signals output on the WDM side within the range of 80 wavelengths in C-band at a 50 GHz channel spacing.

ESC function

Supported

PRBS function

Supports the PRBS function on the WDM side.

LPT function

Not supported

Error correction encoding

FEC, SDFEC2

Performance and alarm monitoring

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

Regeneration

The WDM-side signals from an NS4 board can be regenerated by another NS4 board of the same type.

ALS function

Not supported

Delay measurement (DM)

Supported

Test frames

Not supported

IEEE 1588v2

Not supported

Physical clocks

Supported (ODU0/ODU1/ODU2/ODU2e/ODU3/ODUflex)

Protection scheme

• Supports ODUk SNCP.
• Supports intra-board 1+1 protection (when working with the OLP board).
• Supports tributary SNCP protection.

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.

Loopback

• Supports system-side channel inloops and outloops.
• Supports WDM-side inloops and outloops.

Electrical-layer ASON
