Core Product Positioning
The Cisco SFP-10G-T is a hot‑swappable commercial-grade multirate SFP+ copper transceiver. It delivers 10GBASE-T connectivity over twisted-pair copper cabling, allowing network designers to deploy 10 Gigabit links using existing structured copper wiring instead of fiber. This module provides flexible migration from Gigabit Ethernet to 10G Ethernet for wiring closets, server rack top-of-rack connections and short-reach inter-switch links. It auto-negotiates multiple speed grades for seamless backward compatibility.
2. Hardware & Software Compatibility
Supported Host Platforms
