Typical channel spacing

150GHz+n*6.25GHz (n=0,1,2...)

NOTE:

• Due to high filtering penalty, the board cannot be used with 150G optical-layer boards with fixed channel spacing, such as TNG2UD40 and TNG2UM40.
• The optical layer corresponding to an electrical module with the minimum channel spacing greater than or equal to 150 GHz must be upgraded to V100R023C10 or later. Otherwise, the following functions will be affected:
  • Online optical power detection based on digital optical labels.
  • Fiber connection quality detection in the local wavelength add/drop directions based on digital optical labels.

OTN overhead protocol

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

LPT

Not supported

Intra-board 1+1 protection

Supported

NOTE:

• When the board uses the QSFP28,1310,100GE,-3.1dBm,4dBm,-4.5dBm,LC,SMF,2km,PAM4 or QSFP28,1310,100GE,-1.9dBm,4.8dBm,-6.1dBm,LC,SMF,10km,PAM4 module, intra-board 1+1 protection is not supported on the line side.
• In splicing mode, an SF/SD alarm is reported and switching is triggered when any OTUCn/ODUCn is faulty.

Client 1+1 protection

Supported

NOTE:

When 400GE and FlexE services is accessed, the board does not support client 1+1 protection.

ODUk SNCP

Not supported

Tributary SNCP

Not supported

Optical-layer ASON

Supported

L1 service encryption

Supports setting the encryption function by port.

NOTE:

• When the OTU4 service is accessed, the board does not support encryption.
• ClientLP port encryption is supported in the case of FlexE services.
• The encryption function requires the port-level encryption license.

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 light sensor function to detect optical power and overheads and report optical performance data.

ALS

Supported

LLDP

Supported

NOTE:

• Supports the LLDP function when the client-side service is ethernet.
• LLDP is not supported when FlexE services are received on the client side.
• When the service mapping mode is MAC transparent mapping, the LLDP mode of the port is the Receive mode by default. In this case, LLDP packets are not transparently transmitted.

Physical clock

• On the tributary side:
  • Supports synchronous Ethernet transparent transmission instead of synchronous Ethernet processing when receiving 400GE (BMP)/100GE (GMP) services on the client side.
  • Supports synchronous Ethernet processing instead of synchronous Ethernet transparent transmission when receiving 400GE (IMP)/100GE (IMP)/FlexE services on the client side.
• On the line side: supported

IEEE 1588v2

Supported

NOTE:

Supported only when the client-side service type is 400GE(IMP)/100GE(IMP)/FlexE.

ITU-T G.8275.1

Supported

NOTE:

Supported only when the client-side service type is 400GE(IMP)/100GE(IMP)/FlexE.

ITU-T G.8273.2

Supported

High-precision clock synchronization

Supported

NOTE:

• The high-precision clock synchronization function can be implemented only after the corresponding license is obtained.
• The board must work with the subrack and system control board that support high-precision clock to support the high-precision clock synchronization function. For details, see Clock Synchronization Feature Guide.
• Supported only when the client-side service type is 400GE(IMP)/100GE(IMP).

Outband DCN

Supported

NOTE:

• Supports the function when the client-side service is OTN.
• In splicing mode, DCN is supported only by the first OTUCn channel.

Test frame

Supported

NOTE:

Supports the test frame function when the client-side service is ethernet.

PRBS

• Client-side: Supports the PRBS test function in the backplane direction, and supports the optical port direction when OTN services are received.
• WDM-side: Supports the PRBS test function.

NOTE:

In splicing mode, the PRBS function is enabled for both OTUCn channels.

Latency measurement

• Client side:
  • Supports PM latency measurement for upstream when non-OTN services are received.
  • Supports TCM latency measurement for downstream when OTN services are received.
• Supports latency measurement in the WDM-side optical port direction (upstream direction):
  • When only one ODUk granularity level exists in the mapping path, ODUk channels support only TCM latency measurement.
  • Supports PM and TCM latency measurement at the ODUCn layer.

NOTE:

• Each line-side port supports latency measurement for a maximum of eight channels concurrently.
• In splicing mode, latency measurement is separately configured for two OTUCn channels.
