SFP-T Copper RJ45 Transceiver

An SFP copper transceiver is a pluggable module that fits into a standard SFP or SFP+ port and connects to copper Ethernet cabling via an RJ45 connector — instead of fiber. It allows fiber-port switches to communicate over standard Cat5e/Cat6 copper cable up to 100 meters, without any additional adapters or recabling.

A fiber SFP transceiver transmits data as light pulses over fiber-optic cable, supporting distances ranging from hundreds of meters to 80 km and beyond.

An SFP-to-RJ45 copper module transmits data electrically over standard copper Ethernet cable, with a maximum distance of 100 meters but compatible with existing copper infrastructure — making it a cost-effective option when fiber is not available or necessary.

The choice depends on your network speed requirements.

A 1000BASE-T copper SFP transceiverdelivers 1 Gbps over Cat5e or Cat6 cable, suited for standard enterprise and industrial network connections.

A 10GBASE-T SFP+ copper transceiver delivers 10 Gbps over Cat6a cabling, making it the right choice for high-throughput uplinks, server connections, and bandwidth-intensive applications.

Confirm your switch port type — SFP for 1G, SFP+ for 10G — before ordering.

Wintop's RJ45 copper SFP transceiver modules are MSA-compliant and designed for broad cross-brand compatibility. Compatibility may vary by switch vendor due to proprietary encoding checks on some platforms. Contact our teamwith your switch model to confirm before ordering.
