Chapter 14 Card Reference
The 2.5-Gbps–10-Gbps Muxponder–100 GHz–Tunable xx.xx-xx.xx (MXP_2.5G_10E) card is a
DWDM muxponder for the ONS 15454 platform that supports full optical transparency on the client
side. The card multiplexes four 2.5 Gbps client signals (4 x OC48/STM-16 SFP) into a single 10-Gbps
DWDM optical signal on the trunk side. The MXP_2.5G_10E provides wavelength transmission service
for the four incoming 2.5 Gbps client interfaces. The MXP_2.5G_10E muxponder passes 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 general communication channels (GCC) for data communications, enable forward error
correction, or facilitate performance monitoring.
The MXP_2.5G_10E works with Optical Transparent Network (OTN) devices defined in ITU-T G.709.
The card supports Optical Data Channel Unit 1 (ODU1) to Optical Channel Transport Unit (OTU2)
multiplexing, an industry standard method for asynchronously mapping a SONET/SDH payload into a
digitally wrapped envelope. See the
The MXP_2.5G_10E card is not compatible with the MXP_2.5G_10G card, which does not supports full
optical transparency. The faceplate designation of the card is "4x2.5G 10E MXP."
You can install MXP_2.5G_10E cards in Slots 1 to 6 and 12 to 17. You can provision this card in a linear
configuration, as a BLSR, a path protection, or a regenerator. The card can be used in the middle of
BLSR or 1+1 spans when the card is configured for transparent termination mode.
The MXP_2.5G_10E features a 1550-nm laser on the trunk port and four 1310-nm lasers on the client
ports and contains five transmit and receive connector pairs (labeled) on the card faceplate. The card
uses a dual LC connector on the trunk side and uses SFP modules on the client side for optical cable
termination. The SFP pluggable modules are short reach (SR) or intermediate reach (IR) and support an
LC fiber connector.
The MXP_2.5G_10E card detects SF, LOS, or LOF conditions on the optical facility. Refer to the Cisco
ONS 15454 SONET and DWDM Troubleshooting Guide for a description of these conditions. The card
also counts section and line BIP errors from B1 and B2 byte registers in the section and line overhead.

14.8.5.1 Key Features

The MXP_2.5G_10E card has the following high level features:
•
•

Four 2.5 Gbps client interfaces (OC-48/STM-16) and one 10 Gbps trunk. The four OC-48 signals
are mapped into a ITU-T G.709 OTU2 signal using standard ITU-T G.709 multiplexing.
Onboard Enhanced Forward Error Correction (E-FEC) processor: The processor supports both
standard RS (specified in ITU-T G.709) and E-FEC, which allows an improved gain on trunk
interfaces with a resultant extension of the transmission range on these interfaces. The E-FEC
functionality increases the correction capability of the transponder to improve performance,
allowing operation at a lower OSNR compared to the standard RS (237,255) correction algorithm.
A new BCH algorithm implemented in E-FEC allows recovery of an input BER up to 1E-3.
Pluggable client interface optic modules: The MXP_MP_10E card has modular interfaces. Two
types of optics modules can be plugged into the card. These include an OC-48/STM 16 SR-1
interface with a 7 km nominal range (for short range and intra-office applications) and an IR-1
interface with a range up to 40 km. SR-1 is defined in Telcordia GR-253 and in I-16 (ITU- G.957).
IR-1 is defined in Telcordia GR-253 and in S-16-1 (ITU G.957).
High level provisioning support: The MXP_MP_10E card is initially provisioned using
Cisco MetroPlanner software. Subsequently, the card may be monitored and provisioned using CTC
software.
