Cisco 2.5-Gbps Multi-rate Data Muxponder Card 4ch Protected 2500Mbit/s 1554.94nm network media converter

2.5G Multi-rate Data Muxponder Card Protected The 2.5-Gbps multiservice aggregation line card for the Cisco® ONS 15454 Multiservice Transport Platform (MSTP) provides a highly scalable solution that addresses today's ever-growing requirement for data and storage bandwidth in enterprises as well as metropolitan-area (metro) and regional managed service providers. This 8-port multiservice aggregation card (Figure 1) efficiently uses wavelengths by aggregating Gigabit Ethernet, Fibre Channel, IBM Fiber Connection (FICON), and Enterprise Systems Connection (ESCON) services into a 2.5-Gbps wavelength.

The 2.5-Gbps multiservice aggregation card provides service aggregation of Gigabit Ethernet, Fibre Channel, FICON, and ESCON services over a 2.5-Gbps 100-GHz, ITU-compliant wavelength, with 50-GHz wavelength stability for future 64-channel operation. The card architecture contains eight client interfaces that are electronically multiplexed and converted to a single-line DWDM interface, without accessing the Cisco ONS 15454 shelf cross-connect fabric. A single card multiplexes up to two Gigabit Ethernet, 1-Gbps Fibre Channel or FICON services as well as a single 2-Gbps Fibre Channel or FICON service and up to eight ESCON services. The interface to the client is through a variety of Small Form-Factor Pluggable (SFP) optics modules, facilitating a wide service mix, including Gigabit Ethernet, 1-Gbps or 2-Gbps Fibre Channel, FICON and ESCON, and different fiber types (single-mode and multimode), wavelengths (850 and 1310 nanometers [nm]), and fiber reach (short reach for intraoffice, intermediate reach for short haul, etc.). The SFP optics modules are equipped with LC connectors to enable high-density placement on the card. Because the 2.5-Gbps multiservice aggregation card incorporates both client and DWDM line interfaces into a single card, up to 12 cards can be deployed in the Cisco ONS 15454 platform.

The DWDM line interface provides one long-reach or long-haul, ITU-compliant, 100-GHz spaced optical interface. The DWDM output line interface is tunable across four adjacent 100-GHz wavelengths, facilitating support for 32-channel DWDM networks using only eight separate cards. At each wavelength, the 2.5-Gbps multiservice aggregation card wavelength is offered in protected or unprotected versions. The protected version includes a second DWDM line output or input, helping enable optical line protection over a DWDM network.

The 2.5-Gbps multiservice aggregation card supports many carrier-class features and advanced capabilities including service flexibility, ability to tune wavelengths, flexible protection mechanisms, management, storage-area network (SAN) extension beyond the metro, and performance-monitoring capabilities outlined in the following sections.
