The Cisco SFP-OC3-IR1 is a 155 Mbps OC-3/STM-1 SFP module for single-mode fiber (SMF) with an LC (PC or UPC) connector. Its 15 km reach places it in the intermediate reach (IR) category of the Cisco OC-3 family, between the SR (2 km) for short-distance use and the LR1 (40 km) for longer links, making it a well-suited choice for metropolitan area or extended campus SONET/SDH connections.
This transceiver is appropriate for SONET/SDH deployments requiring coverage from a few kilometers up to around 15 km, typically for connecting telephone exchanges or urban network nodes. The -5 to 85 °C range provides good thermal tolerance. Genuine Cisco hardware, manufacturer warranty.
World leader in networking solutions, Cisco provides trusted infrastructure for the world's largest enterprises and telecom operators.
