Cisco 10GBASE-LR SFP+ Transceiver Module, 1310 nm Single-Mode

A single-mode 10GbE link of up to 10 km is what the Cisco 10GBASE-LR SFP+ Transceiver Module, part number SFP-10G-LR, supports. It operates at 1310 nm and uses a duplex LC connector.

That range covers campus and metro connections, and it is the usual answer when a 10GbE link leaves the building or runs between distant parts of a large facility. The module is an SFP+, so it fits the same cages as short-reach 10GbE modules and the same ports on most server adapters.

The fiber must be single-mode end to end. A multimode segment in the path will make the link unreliable. As with any long-reach optic, loss from splices, connectors and patch panels should be measured against the available budget for your route.

Cisco hosts may restrict which modules they accept, so confirm that your switch supports this part number. A separate S-Class version exists under its own part number, so match the one that your platform lists.

The far end needs a matching 10GBASE-LR module or an equivalent supported by your equipment.

The SFP-10G-LR is offered new and refurbished, each with a choice of 1 year or 3 years of warranty. No used offer is listed. Send your quantity and platform for pricing.
