Arista 25GBASE-ER SFP25 Transceiver, 40 km Single-Mode
SFP-25G-ER · Refurbished · 1 year warranty
Quantity (units)
Overview
Forty kilometers at 25GbE is the rating of the Arista 25GBASE-ER SFP25 Transceiver, part number SFP-25G-ER. It is an SFP28-class module for single-mode fiber with one port at 25GbE.
Spans of this length connect separate sites or buildings without extra transport equipment. As with any long-reach optic, the rating assumes good fiber, and actual performance depends on attenuation, splices and connectors along the route. Measure the loss on your real path before ordering.
Confirm that your cabling matches the module. Both ends of the link need compatible modules, and the host switches or adapters must accept them. Check the supported-optics information for your Arista platform.
For shorter single-mode spans, a lower-rated module can be enough and may cost less. Buying the 40 km module for a short route is possible, but long-reach optics may need attenuation on short spans, so check the manufacturer's guidance for your link length.
The SFP-25G-ER is offered new and refurbished, each with a choice of 1 year or 3 years of warranty. No used offer is listed. Send your quantity and platform to request pricing.
