The StarTech.com AR-SFP-1G-LX-ST is an Arista Networks-compatible 1GbE 1000Base-LX SFP fiber transceiver for network administrators connecting compatible switches or routers over single-mode fiber, with an LC connector and reach up to 10 km.
Recommended For
- Network administrators linking Arista switches or routers across a single-mode fiber run, such as a campus or building-to-building connection, at 1 GbE and up to the module’s rated 10 km reach.
- IT teams replacing a failed Arista-compatible 1 GbE LX optic while keeping an existing 1310 nm, LC-terminated single-mode fiber link in service.
- Technicians adding or swapping an optic in a compatible switch or router who want a hot-swappable module with digital diagnostics monitoring.
Real-World Use Scenarios
- An IT team connects two compatible Arista switches in separate buildings over installed single-mode fiber; the link provides a 1 GbE network connection across the site, within the fiber link’s supported reach.
- A network administrator extends a fiber uplink from an Arista switch or router to a remote equipment room; using matching 1G LX optics at both ends can provide connectivity where a copper run is unsuitable or too short.
- A business replaces a failed or mismatched 1G LX optic in a compatible Arista device; the hot-swappable module lets the technician change the transceiver without removing the switch or router from service, though the affected link will be interrupted during the swap.
- A network team uses the transceiver for a 1 GbE fiber handoff from a service provider; the connection works when the provider’s optic, fiber type, link speed, and the customer device’s compatibility requirements match.
- An administrator checks a fiber link through network-management software; the module’s DDM support can report transceiver status to compatible monitoring tools, helping with routine troubleshooting.
