SFP-OC3-LR1 — SFP 155 Mbps

The Cisco SFP-OC3-LR1 is a 155 Mbps SFP transceiver compliant with OC-3/STM-1, for single-mode fiber (SMF) with an LC (PC or UPC) connector. Its 40 km reach positions it between the IR1 variant (15 km) and the LR2 (80 km) of the same OC-3 family, offering an intermediate solution for long-reach SONET/SDH links without requiring the extreme distances of the LR2.

It targets telecom operators and equipment vendors deploying OC-3/STM-1 links over medium to long distances, particularly for connecting regional network nodes. Its temperature range of -5 to 85 °C ensures reliable operation in standard technical facilities. Genuine Cisco hardware, manufacturer warranty.
