The 4-port 10 Gigabit Small Form-Factor Pluggable (XFP)-based 10 Gigabit Ethernet transponder card for the Cisco® ONS 15454 Multiservice Transport Platform (MSTP) simplifies the integration and transport of OTU2, 10 Gigabit Ethernet (10GE), 10 Gigabit Fibre Channel (10G FC), and OC-192/STM-64 interfaces and services into enterprises or metropolitan-area (metro) and regional service provider networks.BackgroundMetro transport networks must support numerous service demands, from low-rate DS-1/T1, DS-3/E3, 10/100BASE-T, and OC-3/STM-1 to higher-rate OC-12/STM-4, Gigabit Ethernet, OC-48/STM-16, OC-192/STM-64, 10 Gigabit Ethernet, 10 Gigabit Fibre Channel, and OC-768/STM-256 services. The flexibility to support multiple rates brings huge savings in terms of operating and management costs.
