Cisco OC48E POS-SR-SC-B Network Interface Card is a 1-port Packet-over-Sonet (POS) interface for OC-48c STM-16c SONET/SDH networks. It supports 1310 nm short-reach (SR) transmission with an SC fiber connector and carries the GSR designation. This card enables POS traffic to traverse OC-48c SONET/SDH frames, making it suitable for high-capacity transport needs in Cisco GSR deployments.
