a variety of muxponder cards provides a more cost-effective networking solution to facilitate the delivery of all data,
storage area networking (SAN), and TDM services.
Product Overview
The Cisco ONS 15454 8-Port 10-Gbps Data Muxponder Card can transport up to 8 x 1-Gbps services, 4 x 2-Gbps
services, 2 x 4-Gbps services, or a mix of these services aggregated over a G.709 OTU-2-based, 50-GHz spaced,
50-GHz stabilized, ITU-compliant wavelength with selectable Forward Error Correction (FEC), Enhanced Forward
Error Correction (E-FEC). The muxponder card is a plug-in module to the Cisco ONS 15454 MSTP, helping enable
a high-density, cost-effective solution for Gigabit Ethernet, Fibre Channel, FICON, and ISC transport over a highly
resilient optical platform. The muxponder card architecture contains eight client interfaces that are mapped to a
single line interface, without accessing the Cisco ONS 15454 shelf cross-connect fabric.
Each client interface supports Gigabit Ethernet, 1-Gbps or 2-Gbps Fibre Channel/FICON/ISC, or 4-Gbps Fibre
Channel using a Small Form-Factor Pluggable (SFP) optics module with LC connectors, providing the flexibility to
support several protocols, data rates, or fiber types with support for qualified SFP modules. The data muxponder
card supports a mixture of SFP types and also supports in-service insertion or removal without affecting other
active ports, allowing networking flexibility and reduced pre-planning activities.
The DWDM line interface provides one 10.70923-Gbps G.709 OTU-2 digital wrapper, long-reach/long-haul, ITU-
compliant, 50-GHz spaced optical interface using LC connectors supporting G.709 OTU-2 digital wrapper
interfaces. The DWDM output line interface is tunable across the full optical C or L band, dramatically reducing the
inventory of spares. When operated within the outlined specifications, each card will transport the aggregated
signals with a maximum bit error rate (BER) of 10E-15.
The muxponder card incorporates the eight client interfaces and one DWDM line interface on the same card. The
muxponder cards are deployable in the 12 multiservice interface card slots of the Cisco ONS 15454 MSTP, in
systems with or without cross-connect cards. The addition of a cross-connect card enables the platform to support
hybrid applications containing transparent 2.5-Gbps services as well as aggregation of the other services
supported by the Cisco ONS 15454 MSTP. The only other common card required for operation is the timing,
communications, and control (TCC) card.
The data muxponder card provides many carrier-class features and capabilities necessary to deliver SAN and data
services, including selectable service mix, wavelength tunability, flexible protection mechanisms, flexible timing
options, and management capabilities.
Enhanced FEC Capability
An important feature of the data muxponder card is its ability to configure the Forward Error Correction in three
modes: NO FEC, FEC, and E-FEC. The output bit rate will always be 10.7092 Gbps as defined in G.709 but the
error-coding performance can be provisioned:
NO FEC: no Forward Error Correction
FEC: standard G.975 Reed-Salomon algorithm
E-FEC: standard G.975.1 two orthogonally concatenated BCH super FEC code. This FEC scheme contains
three parameterizations of the same scheme of two orthogonally interleaved block codes (BCH). The
constructed code is decoded iteratively to achieve the expected performance.
Note: E-FEC gains 2 dB when compared to standard FEC.
