Arista-compatible 10 Gbps SFP+ transceiver

This module is an Arista Networks SFP-10G-LR compatible SFP+ transceiver built for 10 GbE links over single-mode fiber. It operates at a 1310 nm wavelength with LC connectors and reaches up to 10 km. Network engineers deploying Arista switches and routers use it to extend connectivity across campus or metro distances.

Hot-swappable LC module with DDM

The transceiver is hot-swappable, so it can be inserted or removed without powering down the switch, keeping network disruption to a minimum. Digital Diagnostics Monitoring is supported, giving real-time visibility into optical power, temperature and voltage. Installers should verify that the host port accepts Arista-coded modules and that single-mode patch cords with LC connectors are used; mismatched fiber type or coding will prevent the link from coming up.

10 km reach at 10 Gbps on single-mode fiber

At 10 Gbps the module comfortably handles campus backbone and building-to-building runs up to 10 km (6.2 mi) on standard single-mode fiber. Beyond that distance the optical budget is exhausted and errors increase, so longer spans require a different wavelength or amplification. Power draw stays below 1.3 W, and the published MTBF exceeds 1.3 billion hours, indicating ample headroom for continuous operation in aggregation or core layers.

Questions about this item

How can I verify the module is operating correctly once installed in my Arista switch?

The transceiver supports Digital Diagnostics Monitoring so you can check real-time temperature, voltage, bias current and optical power levels through the switch CLI to confirm it is within the 1.3 W power budget and 10 Gbps link rate.

What comes in the package and is any cabling included?

The box contains the SFP+ transceiver module only; you must purchase LC-terminated single-mode fiber patch cords separately to complete the 10 km link.

Which version should I choose for a 10 km single-mode run at 1310 nm?

This model is the 10GBASE-LR variant rated for 10 km over single-mode fiber at 1310 nm, matching the stated maximum distance of 10 km (6.2 mi).
