Arista 25GBASE-SR SFP Transceiver Module, Multimode LC
SFP-25G-SR · Refurbished · 1 year warranty
Quantity (units)
Overview
Server links at 25GbE over multimode fiber are the target of the Arista 25GBASE-SR SFP Transceiver Module, part number SFP-25G-SR. It uses a duplex LC connector and reaches 70 m on OM3 and 100 m on OM4. The form factor is SFP28.
Those distances cover most top-of-rack and end-of-row connections. As the OM3 and OM4 ratings differ, check the fiber grade in your plant, and measure each run instead of relying on the floor plan.
The SFP28 cage is the standard port style for 25GbE on switches and server adapters, and it also accepts lower-speed SFP+ modules on many platforms. This module is for the 25GbE case, with a compatible short-reach module on the other end.
Check the manufacturer's data for the wavelength and any FEC requirement. Forward error correction at 25GbE is a host setting, so check your switch and adapter documentation for the mode the link needs.
Arista keeps a list of supported optics for its switches, and the adapter on the server side may restrict what it accepts, so verify both before ordering.
The SFP-25G-SR is available 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.
