The Cisco ONS 15454 MSPP 4x 2.5-Gbps muxponder card can transport four OC-48/STM-16 payloads over an OC-192/STM-64-based, 100-GHz spaced, 50GHz stabilized, ITU-compliant wavelength with provisionable digital wrapper (G.709) and selectable forward error correction (FEC). The muxponder card is a plug-in module to the Cisco ONS 15454 MSPP, enabling a high-density, cost-effective solution for OC-48/STM-16 services transport over a platform capable of low-rate services down to 1.5 Mbps. The muxponder card architecture contains four client interfaces that are mapped to a single line interface, without accessing the Cisco ONS 15454 shelf cross-connect fabric.Each client interface provides a 2.488-Mbps (OC-48/STM-16) SONET/Synchronous Digital Hierarchy (SDH) interface via a small-form-factor-pluggable (SFP) optics module with LC connectors, providing the flexibility to support several optical reaches, including short-reach/intra-office, intermediate-reach/short-haul, and long-reach/long-haul, with support for qualified DWDM and DWDM SFP modules. The muxponder card supports any mixture of SFP reach types and also supports in-service insertion or removal without affecting other active ports, allowing ultimate networking flexibility and reduced pre-planning activities.The DWDM line interface provides one 9.95328-Gbps (OC-192/STM-64) or 10.70923-Gbps (OC-192/STM-64 with G.709 digital wrapper enabled), long-reach/long-haul, ITU-compliant, 100-GHz spaced optical interface using LC connectors supporting OC-48/STM-64 interfaces. The DWDM output line interface is tunable across two adjacent 100-GHz wavelengths, reducing inventories for spares. Using amplification and dispersion compensation, the muxponder card is capable of a 300-km reach. When operated within the outlined specifications, each card will transport the 10-Gbps signal with a maximum bit error rate (BER) of 10E-15.The muxponder card incorporates the four clients 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 platform, 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 platform. The only other common card required for operation is the timing, communications, and control (TCC) card.The muxponder card provides many carrier-class features and capabilities necessary to deliver 2.5-Gbps services, including selectable protocol transparency, wavelength tunability, flexible protection mechanisms, flexible timing options, and management capabilities.
