About the SFP-10G-LR-AR

The Arista SFP-10G-LR-AR optical transceiver delivers long-reach 10 Gigabit Ethernet connectivity for enterprise campus backbones and data center aggregation networks. Operating at a central wavelength of 1310 nanometers over standard duplex single mode optical fibre, it enables low latency high reliability links up to 10 kilometers without amplification.

Compatibility

Compatible with Arista 7050 Series, 7150 Series, 7280 Series, and 7500 Series modular line cards. It inserts into any standard SFP+ port and is recognized natively by Arista EOS without requiring service unlock keys or software feature licenses across enterprise deployments.

How to identify a genuine unit

Packaged in an SFP+ form factor metallic shell with a blue extraction latch bail that designates longwave single mode optical operation. The top label bears the Arista Networks logo, model designation SFP-10G-LR, serial number barcode, and international laser safety certification markers.

Buying used

Inspect the dual LC optical receptacle with a fiber microscope to verify clean optical surfaces free of scratches or oil residues. Mount the transceiver into a live EOS switch cage to confirm that the port authenticates cleanly and reports calibrated optical power levels within factory thresholds.

Works together

How the Arista SFP-10G-LR-AR connects to servers, storage and the network: 3 ways, with the hardware on each path.

iSCSI and NVMe/TCP over EthernetFile storage (NFS and SMB)Hyperconverged cluster

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.

Storage

iSCSI and NVMe/TCP over Ethernet: how it fits together

File storage (NFS and SMB)

Front-end ports face the clients; back-end ports (on scale-out systems) connect the nodes to each other and need their own switch pair.

Hyperconverged cluster

Plan at least two 25GbE ports per node to two switches; all-NVMe clusters often move to 100GbE.
