Description

This 1000BASE-LX SFP transceiver provides Gigabit Ethernet over duplex single-mode fibre, with a reach of up to 10km at 1310nm through an LC connector. It suits 1G uplinks and campus, data centre or metro links, as well as short multimode runs of up to 550m when mode conditioning is used.

It operates at 1 Gbps in the SFP form factor and is hot swappable, so it can be fitted or replaced without taking the switch out of service. Over single-mode fibre (G.652) it covers up to 10km. Over multimode fibre it reaches up to 550m, with a mode conditioning patch cord required on OM1 and OM2 and not required on OM3. This is the standard-temperature version, and no licence is required.

It works in Arista switches with SFP, SFP+ or SFP28 ports and is supported on all current EOS releases. For 1000BASE-LX on a 10G host port using rate adaptation, the matching part is SFP-10G-RA-1G-LX. The extended-temperature version is SFP-1G-LX-H, which needs EOS 4.36.0 or later.

Enquire with XS Network Tech for new or used pricing and availability.

Q: Which Arista switches does it work with?
A: Arista switches with SFP, SFP+ or SFP28 ports, on all supported EOS releases.

Q: How do I run 1000BASE-LX on a 10G host port?
A: Use SFP-10G-RA-1G-LX, which provides 1000BASE-LX through rate adaptation on a 10G port.

Q: Is there an extended-temperature version?
A: Yes. SFP-1G-LX-H is the extended-temperature version and needs EOS 4.36.0 or later. This SKU is the standard-temperature part.
