Feature Description

OC Support for 10G Grey Mux

Cisco IOS XR Release 7.5.2

You can now configure a 10x10G muxponder on each slice of the OTN-XP line card. The 10x10G muxponder multiplexes ten 10G clients and map it to a grey OTU4 trunk signal. This feature improves efficiency, performance, and flexibility for customer networks allowing 10x10G client transport over 100G WDM wavelength.

Slices and Port Mapping on 10G Grey Mux

You can configure the 10G Grey Mux with slices 0 and 1. The following tables show port maping for slices 0 and 1.

Supported Payloads, OC Models, and Features

This section describes about the supported payloads, OC models, and features by 10G Grey Mux.:

Supported Payloads

The supported payloads are defined by the client bit rate and ODU rate that can be configured on the BO-LC 10g-grey-mxp mode.

Client Bit Rate

The possible client bit rate can be:

  • 10GE (All 10 lanes of a slice set to 10GE rate).

  • OTU2 (All 10 lanes of a slice set to OTU2 rate).

  • Mix (A mix of 10GE, OTU2, and OTU2e rates configured on a slice.

ODU Rate

The possible ODU rate can be:

  • ODU2e– mapper for 10GE.

  • ODU2e- client and LO-ODU for OTU2e clients.

  • ODU2– client and LO-ODU for OTU2 clients.


Note

The ODU rates are not user configurable.
