The Cisco OC192E/POS-IR-SC is a line card module used in Cisco routers. It is designed to provide high-speed optical connectivity for transmitting data at OC-192 (Optical Carrier 192) rates, which is equivalent to 9.953 Gbps (Gigabits per second). The "POS" in the name stands for Packet over SONET (Synchronous Optical Networking), which is a protocol used for transmitting data over optical networks. The "IR" indicates that it is an intermediate reach module, capable of transmitting data over a certain distance. The "SC" refers to the type of optical connector used, which is the Subscriber Connector. Overall, the Cisco OC192E/POS-IR-SC is a module used for high-speed optical networking in Cisco routers.
