Arista-compatible 10GBASE-T transceiver

The STARTECH AR-SFP-10G-T-ST is an SFP+ copper module built for 10 Gbps Ethernet links over RJ-45 cabling. It is programmed and tested for Arista Networks switches and routers, targeting network engineers who need dependable 10GbE connectivity using existing copper infrastructure.

Upgrading from 1 GbE copper links

This module replaces 100/1000Base-TX transceivers when bandwidth must move to 10 Gbps without changing to fibre. The jump is worth it when aggregation uplinks or server connections saturate 1 GbE and the installed Cat6 or Cat5e runs are within the supported distance.

30-metre reach on Cat6 or Cat5e

The 10GBASE-T standard limits this transceiver to 30 m (98.4 ft) over qualified copper cable. Signal integrity drops beyond that range, so longer runs require fibre-based SFP+ modules instead. The RJ-45 interface also means higher latency and power draw compared to direct-attach or optical alternatives.

Questions about this item

Will this SFP+ module fit a standard SFP+ cage in an Arista switch?

Yes, the module uses the industry-standard SFP+ form factor and plugs directly into any compatible Arista SFP+ port.

How do I install the transceiver and which step is often missed?

Insert the module until it clicks, then connect a Cat6 or Cat5e patch cable to the RJ-45 port; the step often missed is verifying the link LEDs on both ends.

What cable type and maximum length should I plan for future replacements?

Use Cat6 or Cat5e copper cabling and keep runs within 30 m (98.4 ft) to maintain 10 Gbps performance.
