S10G-LR-PM-D-I — SFP+ 10 Gbps

The S10G-LR-PM-D-I from Cisco is a 10 Gbps SFP+ module on single-mode fibre (SMF), compliant with the IEEE 10GBASE-LR standard, with an LC (UPC) duplex connector and a reach of 10 km. It operates across an industrial temperature range of -40 to 85°C, making it suitable for both air-conditioned server rooms and outdoor technical enclosures.

This reference is widely preferred for 10G inter-building connections on campus or between two nearby datacenters linked by dark single-mode fibre. The S10G-LR-PM-D-I sits between the S10G-SR-PM-D-I (150 m, multimode) and the S10G-ER-PM-D-I (40 km, single-mode), covering exactly the 10-kilometre link requirement.
