StarTech.com AR-SFP-10G-T-ST 10G SFP+ Copper Transceiver Module for Arista Networks, RJ45, 100m, DDM

Unlike generic SFP+ modules that force you into costly fiber upgrades, the StarTech.com AR-SFP-10G-T-ST unlocks 10 Gigabit speeds over ordinary copper cabling you already have. This Arista Networks-compatible transceiver plugs into any standard SFP+ slot and delivers 10GBase-T connectivity through a familiar RJ45 port, eliminating the need for new infrastructure. With support for 100 Mbps, 1 Gbps, and 10 Gbps, it adapts to your network's current speed and grows with future demands. Digital Diagnostic Monitoring (DDM) provides real-time visibility into temperature, voltage, and optical power, so you can troubleshoot before issues escalate. Hot-swappable design means zero downtime during installation or replacement. Built with a rugged zinc alloy housing and engineered for 3,000,000 hours MTBF, this module is a reliable workhorse for data centers, enterprise wiring closets, and high-performance workstations.

Highlights

• 10GBase-T over copper: Achieve 10 Gbps up to 30 meters using CAT6a/CAT7 cable—no fiber required.
• Tri-speed flexibility: Auto-negotiates 100 Mbps, 1 Gbps, and 10 Gbps for seamless integration.
• Arista Networks compatibility: Tested and certified for Arista switches and routers.
• DDM support: Monitor real-time diagnostics: temperature, voltage, TX/RX power, and more.
• Hot-swappable: Install or remove without powering down your network device.
• Durable build: Zinc alloy enclosure with 3,000,000 hours MTBF for long-term reliability.

In daily use

Imagine upgrading a legacy 1G copper link to 10G without pulling new fiber. The AR-SFP-10G-T-ST makes that possible. Simply insert the module into an SFP+ port, connect a standard CAT6a patch cable, and the link comes up at 10 Gbps. For shorter runs or mixed environments, it gracefully steps down to 1 Gbps or 100 Mbps. Network administrators appreciate the DDM feature—using compatible Arista software, they can monitor the module's health remotely and predict failures. The low power consumption (under 2.5W typical) helps keep energy costs down in dense deployments. Whether connecting servers, storage arrays, or top-of-rack switches, this transceiver delivers consistent, low-latency performance.
