Tunable wavelength

TNG3M504SP supports tunable wavelengths of WDM-side optical signals in Super C band (1524 nm to 1573 nm).

FEC coding

• Client side:
  • OTU4: FEC
  • Ethernet services, FlexE services: RS_FEC
• WDM side:
  • 400G s16QAM: SDFEC3

Line modulation format

400G s16QAM

Typical channel spacing

400G s16QAM: 100GHz+n*6.25GHz(n=0,1,2...)

NOTE:

Due to high filtering penalty, 400G s16QAM cannot be used with 100G optical-layer boards with fixed channel spacing, such as TNG2D60 and TNG2M60.

OTN overhead protocol

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

OTN overhead

ODUflex/ODUC4 layer: supports PM and TCM overhead processing.

ODU4 layer:

• Supports PM and TCM overhead processing when 100GE services are received on the client side.
• Supports PM and TCM overhead processing when OTU4 services are received on the client side. This board supports non-intrusive monitoring of PM and TCM overheads.
• Supports SM overhead processing at the OTU4 layer on the client side.

ODUC4 layer: supports SM overhead processing on the WDM side.

LPT

Not supported

Intra-board 1+1 protection

Supported

NOTE:

• Supports intra-board 1+1 protection when working with optical protection boards.

Client 1+1 protection

Supported

NOTE:

• Client 1+1 protection is supported only when 100GE/OTU4 ports are used.
• When 100GE services are received on the client side, client 1+1 protection supports bidirectional switching rather than unidirectional switching. When OTU4 services are received on the client side, client 1+1 protection supports unidirectional switching only.

• Supported when ethernet services or FlexE services are accessed.

Digital optical label

When LS Ability is enabled, the board supports loading low-frequency pilot-tone modulation signals and overheads during wavelength conversion, and can work the optical-layer board that supports the digital optical label function to detect optical power and overheads and report optical performance data.

ALS

Supports the ALS function on the client side when client services are non-OTN services.

LLDP

Supported

NOTE:

• Supports the LLDP function when the client-side service is ethernet.
• The board does not support LLDP when receiving OTU4 and FlexE services.
• LLDP only supports RX and DISABLE modes.

Physical clock

• Synchronous Ethernet processing is supported when receiving 100GE (GFP-F), 400GE (MACB2B) services.
• Synchronous Ethernet transparent transmission is supported when receiving 100GE (GMP), 400GE (BMP) and FlexE 100G unaware services.

Test frame

Supported when the client-side service type is 100GE/400GE.

NOTE:

For Ethernet test frames, only one interface can be used to send them at a time.

PRBS

• Supports the PRBS function on the WDM side.
• PRBS signals can be sent from the client-side optical port to the WDM side only when the client-side service type is OTU4 and the board works in Muxponder mode.
• PRBS signals can be sent from the client-side optical port to the system side.

Latency measurement

• Supports PM and TCM latency measurement for upstream higher-order ODU channels.
• Supports PM and TCM latency measurement for upstream lower-order ODU channels when non-OTN services are received on the client side.
• Supports TCM latency measurement for downstream lower-order ODU channels when OTN services are received on the client side.

NOTE:

• In a mapping path, the maximum granularity ODUk channel is the higher-order ODU channel, and other ODUk channels are lower-order ODUk channels.
