Cisco OC48E/POS-SR-SC-B 12000 1-Port OC-48c/STM-16c SONET/SDH, 1310nm, Short Reach, SC Connector

The Cisco 12000 Series One-Port OC-48c/STM-16c POS/SDH line card which provides a unique combination of performance and class-of-service (CoS) features for delivering advanced end-to-end networking features. The high performance switching engine integrates WRED and our innovative ASIC-based queue scheduling algorithm Modified Deficit Round Robin (MDRR). These allow service providers to offer differentiated services with deterministic traffic behavior in the core of the network. This product combines leadership features with industry-leading cost-per-bit metrics for 2.5 Gbps packet optimized transport infrastructures (i.e. $27.1 per Mbit). Taken together, service providers can use this product to build flexible and cost-effective infrastructures to compete effectively in an Internet-driven economy.

The Cisco 12000 Series One-Port OC-48c/STM-16c POS/SDH line card can be configured with either short-reach 1310 nm optics or long-reach 1550 nm optics. Using short-reach 1310 nm optics, a service provider can connect into a traditional SONET/SDH solution or a transponder-based dense wavelength division multiplexing (DWDM) solution. Using long-reach 1550 nm optics (24 dBm power budget), a service provider can light dark fiber and connect two Cisco 12000 Series Internet Routers in a point-to-point configuration to eliminate a transport layer of equipment, helping reduce networking and operational costs.
