About the SFP-10G-T-AR

The Arista SFP-10G-T-AR transceiver module adapts an optical SFP+ cage into an RJ-45 twisted pair Ethernet port delivering 10Gbps line rate. It provides an economical pathway to integrate copper-connected servers, storage nodes, and firewall appliances into existing SFP+ switch fabrics without changing structural copper wiring.

Compatibility

Compatible with Arista 7050, 7150, 7280, and 7020 Series switches. Switch port power budgets should be checked against Arista platform documentation to ensure thermal airflow parameters remain within recommended environmental thresholds during dense copper port configurations.

How to identify a genuine unit

Enclosed in a metal SFP+ housing with an integrated RJ-45 modular jack and locking extraction latch. The manufacturing label clearly displays the Arista Networks brand name, part designation SFP-10G-T, serial number, and electrical power consumption specifications.

Buying used

Inspect the internal RJ-45 contact pins for bending, corrosion, or debris. Seat the module in an active Arista switch SFP+ port, connect Category 6a patch cabling, and verify that link synchronization establishes at full 10Gbps line rate with zero cyclic redundancy check errors.

Works together

How the Arista SFP-10G-T-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.

Storage

File storage (NFS and SMB): how it fits together

Hyperconverged cluster

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

Check compatibility with Arista

Before you buy, confirm the exact configuration against the vendor's own lists: firmware levels, operating systems, adapters and optics that Arista has tested with the Arista SFP-10G-T-AR.

FAQ

What is the maximum cable distance for SFP-10G-T-AR?

It supports transmission distances up to 30 meters over Category 6a or Category 7 twisted pair cabling.

Does this transceiver draw higher power than optical transceivers?

Yes, 10GBASE-T transceivers draw approximately 2.5W to 2.7W per module under active load.
