About the SFP-10G-SR-AR
The Arista SFP-10G-SR is a 10GBASE-SR optical transceiver engineered for high-density enterprise Ethernet networks. Operating over 850nm multimode fibre, it supports transmission distances up to 300 meters on OM3 and 400 meters on OM4 cabling. It delivers consistent data transmission for virtualization hosts, enterprise servers, and network storage targets.
Compatibility
Supported across Arista 7000 Series fixed and modular switches, including the 7050SX3 series dual-speed SFP28 ports. It links reliably with enterprise PCIe 10GbE server network interface cards. It functions natively within Arista EOS with complete hot-plug capability during active switch operation.
How to identify a genuine unit
Housed in a standard SFP+ metallic body with a beige bail clasp latch. The upper surface features an Arista label showing part identifier SFP-10G-SR and serial tracking codes. Arista EOS identifies the transceiver accurately, reporting real-time operating temperature and supply voltage.
Buying used
Examine the optical bores for cleanliness and ensure that the gold electrical pins on the PCB edge connector are free of physical wear. Plug the module into an Arista test switch to verify that link training occurs immediately and DOM telemetry reports normal optical power levels.

Works together
How the Arista SFP-10G-SR-AR connects to servers, storage and the network: 3 ways, with the hardware on each path.
iSCSI and NVMe/TCP over Ethernet
Keep the speed the same at all three points: a 25GbE server, a 25GbE switch port and a 25GbE array port. Mixed speeds work but the slowest link sets the pace.
