The MXP_MR_10DME-C and MXP_MR_10DME-L muxponders pass all SONET/SDH overhead bytes

transparently.

The digital wrapper function (ITU-T G.709 compliant) formats the DWDM wavelength so that it can be

used to set up GCCs for data communications, enable FEC, or facilitate performance monitoring. The

MXP_MR_10DME-C and MXP_MR_10DME-L cards work with OTN devices defined in ITU-T G.709.

The cards support G.709 OTU2 digital wrapper, an industry standard method for asynchronously

mapping a SONET/SDH payload into a digitally wrapped envelope. Aggregation of input service signals

is provided at the SONET level via GFP-T in STS24c or STS48c framing (depending on the service

type).

Note Because the client payload cannot oversubscribe the trunk, a mix of client signals can be accepted, up to

a maximum limit of 10 Gbps.

You can install MXP_MR_10DME-C and MXP_MR_10DME-L cards in Slots 1 to 6 and 12 to 17.

Note The MXP_MR_10DME-C and MXP_MR_10DME-L cards are not compatible with the

MXP_2.5G_10G card, which does not support full optical transparency.

The MXP_MR_10DME-C card features a tunable 1550-nm C-band laser on the trunk port. The laser is

tunable across 82 wavelengths on the ITU grid with 50-GHz spacing between wavelengths. The

MXP_MR_10DME_L features a tunable 1580-nm L-band laser on the trunk port. The laser is tunable

across 80 wavelengths on the ITU grid, also with 50-GHz spacing. Each card features four 1310-nm

lasers on the client ports and contains five transmit and receive connector pairs (labeled) on the card

faceplate. The cards use dual LC connectors on the trunk side and use SFP modules on the client side

for optical cable termination. The SFP pluggable modules are SX multimode or LX single-mode

interface and support an LC fiber connector.

Details regarding the input data rate, encapsulation method, and data rates available for each client

interface can be found in the Cisco ONS 15454 DWDM Installation and Operations Guide.

A buffer-to-buffer credit management scheme provides FC flow control. With this feature enabled, a port

indicates the number of frames that can be sent to it (its buffer credit), before the sender is required to

stop transmitting and wait for the receipt of a “ready” indication The MXP_MR_10DME-C and

MXP_MR_10DME-L cards support FC credit-based flow control with a buffer-to-buffer credit

extension of up to 1600 km for 1G FC. up to 800 km for 2G FC, or up to 400km for 4G FC. The feature

can be enabled or disabled.
