Arista-compatible 1 Gbps SFP

The STARTECH AR-SFP-1G-LX-ST is a hot-swappable transceiver built for Arista Networks switches and routers. It provides 1000Base-LX connectivity over single-mode fibre for network links up to 10 km (6.2 mi). Network administrators deploying campus or metro links use this module to extend reach beyond copper limits.

LC duplex interface and hot-swap design

An LC duplex connector secures the single-mode fibre pair in a standard SFP footprint measuring .49" x 2.23" x .54" and weighing .63 oz. Hot-swappable operation lets technicians replace or upgrade links without powering down the switch, keeping production traffic flowing during maintenance windows.

10 km reach at 1310 nm with DDM

The 1310 nm wavelength supports the rated 10 km distance on OS2 fibre while drawing less than 1.3 W. Digital Diagnostics Monitoring reports real-time temperature, voltage and optical power so operators can detect degradation before a link fails. Buyers needing longer spans or multi-mode cabling must select a different module.
