The 10-Gbps multirate transponder card can transport 10 Gigabit Ethernet, SONET OC-192, and Synchronous Digital Hierarchy (SDH) STM-64 services over a 100-GHz spaced, 50GHz stabilized, ITU-compliant wavelength. The transponder card is a plug-in module to the Cisco ONS 15454 MSPP, enabling a cost-effective architecture for delivering high-rate 10-Gbps services as well as low-rate services down to 1.5 Mbps. The 10-Gbps transponder card architecture contains a single client interface that is mapped to a single line interface, without accessing the Cisco ONS 15454 shelf cross-connect fabric.The client interface supports 10 Gigabit Ethernet LAN physical layer (PHY), 10 Gigabit Ethernet WAN PHY, SONET OC-192, and SDH STM-64 signals. The interface to the client is a short-reach/intra-office, 1310-nm optical interface using LC connectors supporting fiber distances of up to 2 km (with or without the Y-protection option).The line interface provides one 10-Gbps, long-reach, ITU-compliant, 100-GHz-spaced optical interface using LC connectors supporting OC-192, STM-64, 10 Gigabit Ethernet LAN PHY, or 10 Gigabit Ethernet WAN PHY interfaces. The DWDM output line interface is tunable across two adjacent 100-GHz wavelengths, enabling support for 32 channel DWDM networks via 16 discrete card types. Using amplification and dispersion compensation, the 10-Gbps transponder 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 bite error rate (BER) of 10E-15.The 10-Gbps transponder card incorporates both a client and DWDM line interface on the same card. The 10-Gbps transponder 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 10-Gbps services as well as aggregation of other services supported by the Cisco ONS 15454 platform. The only required common card is the appropriate timing, communications, and control card.The 10-Gbps transponder card provides many carrier-class features and advanced capabilities necessary to deliver 10-Gbps services, including the protocol transparency, wavelength tunability, flexible protection mechanisms, flow-through timing, management, and performance monitoring capabilities.
