Cisco 10GBASE-LR SFP+ Module

This Cisco SFP+ transceiver is designed for 10 Gigabit Ethernet links over single-mode fibre. It suits network engineers and data-centre operators who need reliable long-reach connectivity between switches or routers.

Sustained long-reach operation

The module supports 10GBase-LR signalling for extended distances on single-mode fibre. Enterprise-class components maintain stable performance during continuous high-throughput traffic without the distance limits seen on multimode alternatives.

Compatibility check before ordering

Verify that your switch or router accepts Cisco SFP+ modules and has an available LC duplex port. Confirm the fibre plant is single-mode with LC/PC connectors and that the required link distance fits within the 10GBase-LR specification.

Questions about this item

How much heat and power does the SFP-10G-LR-S= generate when running continuously?

The module is a passive optical transceiver with no fan or active cooling; power draw and thermal output are low enough for standard SFP+ cages in enterprise switches and routers.

What existing equipment is required to use this transceiver?

A switch or router with an open SFP+ port, LC duplex single-mode fibre patch cables, and a compatible 10GBASE-LR link partner at the far end.

Will this LR module work alongside older SR multimode transceivers in the same chassis?

No, LR optics are designed for single-mode fibre while SR optics use multimode fibre; they require different cable plants and cannot link to each other.
