Arista SFP-10G-T 10GBASE-T Copper RJ45 30m Cat6a SFP+ Transceiver

The Arista SFP-10G-T is an SFP+ copper transceiver that lets you connect a 10 Gigabit device over standard twisted-pair cabling instead of fiber. It runs at 10 Gbps only, as 10GBASE-T, and does not step down to 1G or 100M. It reaches up to 30 meters over Category 6a twisted-pair cable and uses an RJ-45 connector with a bail latch. Arista rates its maximum power at 2W and lists EOS 4.23.2 as the minimum software release. Use Cat6a cable rated for 10GBASE-T, and keep each run, including patch cords, to 30 meters or less.

Arista supports the SFP-10G-T in all SFP25 ports and in selected SFP+ ports, because 10GBASE-T modules draw more power than fiber optics. Check Arista's transceiver compatibility guide for your switch before you order, and plan for the module running warmer than a fiber SFP+.

If your runs are longer than 30 meters, the SFP-10G-SR 10GBASE-SR multimode fiber transceiver is the usual choice. For short links inside a rack, the CAB-SFP-SFP-3M 3m 10G SFP+ direct attach copper cable uses less power. For 1G copper ports, see the SFP-1G-T 1000BASE-T transceiver. A new SFP-10G-T is also available.

This seller refurbished SFP-10G-T transceiver is tested, working, and covered by the NetworkTigers one-year warranty.
