Arista-compatible 1 Gbps SFP module

This StarTech.com transceiver is built, programmed and tested for Arista Networks switches and routers. It provides 1000Base-SX connectivity over multi-mode fibre at 850 nm wavelength. The LC duplex interface supports link distances up to 550 m (1804 ft). Hot-swappable design allows installation without network downtime.

Suited for Arista 1G uplinks.

Network engineers expanding or repairing Arista 1GbE fibre links will find drop-in compatibility and DDM monitoring. Buyers needing single-mode fibre, 10 Gbps speeds or distances beyond 550 m must select a different module. The LC connector also rules out SC or MPO patch panels.

Deciding spec: 550 m multi-mode reach at 850 nm

The 550 m maximum distance on OM2/OM3 multi-mode fibre determines whether this part fits the link budget. If the run exceeds 550 m or uses single-mode cable, this transceiver will not work. Match the wavelength and distance to the installed plant before ordering.

Questions about this item

Which version of the Arista SFP-1G-SX compatible transceiver should I select?

The AR-SFP-1G-SX-ST is a single model that delivers 1000 Mbps over multi-mode fiber at 850nm with LC connectors, reaching up to 550 m.

What does the 1000 Mbps rating mean when the module is installed in a switch?

It provides 1 GbE connectivity compliant with 1000Base-SX, so the link runs at full gigabit speed over multi-mode fiber up to 550 m.

Does the LC interface limit the distance or speed in practice?

The LC connector supports the specified 550 m reach at 1000 Mbps over 850nm multi-mode fiber, and the module includes Digital Diagnostics Monitoring.
