Preserve 10 GbE performance on copper infrastructure with an SFP+ RJ-45 transceiver designed for short-reach switch-to-switch and switch-to-server links. This module supports 10GBASE-T over twisted-pair cabling up to 30 m, making it a practical choice for rack-level connections where fiber is unnecessary and cable changes need to stay simple. For infrastructure teams, the value is in compatibility and speed of deployment. An RJ-45 interface lets you reuse structured cabling already in place, reducing the cost and coordination that often come with optical upgrades. The SFP+ form factor keeps the module aligned with high-density switch environments, while the 10 GbE data rate supports bandwidth-hungry workloads, virtualization clusters, and storage traffic that outgrow 1 GbE links. Choose this module when you need a clean path to higher throughput without redesigning the physical layer. It is well suited to enterprise closets, edge aggregation, and short-distance uplinks where dependable copper connectivity is the right fit.
