Backplane capacity

The maximum capacity is 400 Gbit/s.

Client-side service type

• 200GE: Ethernet service at a rate of 206.25 Gbit/s
• 100GE: Ethernet service at a rate of 103.125 Gbit/s
• OTU4: OTN service at a rate of 111.81 Gbit/s
• 50GE: Ethernet service at a rate of 51.5625 Gbit/s
• 40GE: Ethernet service at a rate of 41.25 Gbit/s
• 50G FlexE unaware: flexible Ethernet service at a rate of 51.5625 Gbit/s
• 100G FlexE unaware: flexible Ethernet service at a rate of 103.125 Gbit/s
• 200G FlexE aware: flexible Ethernet service at a rate of 206.25 Gbit/s

NOTE:

The client-side port type is QSFP4*28G by default, and the access service type can be set to 100GE or OTU4. If other client-side services need to be transmitted or received, the port type must be changed.

For example, if 50GE services need to be transmitted or received, you need to change the port type to Client Side Grey Optical Port. If 200GE services need to be transmitted or received, you need to change the port type to Lane4*56G.

For a T502 board, two physical ports cannot be bound to a FlexE group.

• Supports IEEE 1588v2 only when the board receives FlexE Unaware (100G) and FlexE Aware (200G) services on the client side.

ITU-T G.8275.1

• The board supports IEEE 1588v2 only when 100GE/50GE/200GE services are received on the client side, and the port service mapping mode is MAC Transparent Mapping.
• Supports ITU-T G.8275.1 only when the board receives FlexE Unaware (100G) and FlexE Aware (200G) services on the client side.

ITU-T G.8273.2

Supported

NOTE:

• The board does not support ITU-T G.8273.2 when the system control board is U2CTU.
• The board supports ITU-T G.8273.2 only when 50GE/100GE/200GE services are received on the client side, and the port service mapping mode is MAC Transparent Mapping.
• Supports this function only when the board receives FlexE Unaware (100G) and FlexE Aware (200G) services on the client side.

High-precision clock synchronization

Supported

NOTE:

• This function is not supported when the board uses the QSFP28,1310,100GE,-3.1dBm,4dBm,-4.5dBm,LC,SMF,2km,PAM4 module.
• The board supports High-precision clock synchronization only when 100GE/50GE/200GE services are received on the client side, and the port service mapping mode is MAC Transparent Mapping.
• 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.
• High-precision clock synchronization is not supported in the case of FlexE services.

Outband DCN

Supportes when the client-side service type is OTU4.
