Adder SFP-CATX-RJ45 1Gbps Copper SFP Transceiver Module (1000BASE-T, RJ-45, MSA)

The Adder SFP-CATX-RJ45 stands out as a purpose-built copper SFP transceiver that bridges the gap between fibre-ready switches and traditional twisted-pair cabling. Rather than forcing a costly fibre migration, this module lets you run Gigabit Ethernet over existing CAT5e, CAT6, or CAT7 infrastructure up to 100 metres, making it a practical choice for extending network reach without replacing core hardware. Its MSA compliance ensures drop-in compatibility with a wide range of networking equipment, while the hot-swappable design minimises downtime during installation or maintenance.

Highlights

• 1000BASE-T copper SFP transceiver with RJ-45 connector
• Supports CAT5e, CAT6, and CAT7 cabling up to 100 m
• Full-duplex Gigabit Ethernet at 1 Gbps
• Hot-swappable and MSA compliant for broad compatibility
• Low power consumption under 1.0 W, powered by 3.3 V
• Operating temperature range from 0°C to 70°C

In daily use

In a typical deployment, the SFP-CATX-RJ45 slots into any standard SFP port on a switch, router, or media converter, instantly providing an RJ-45 interface for copper connections. This is especially useful when linking to devices that lack fibre ports, such as older servers, IP cameras, or access points. The module negotiates link speed automatically and maintains stable full-duplex throughput, ensuring smooth data transfers for bandwidth-intensive applications. Because it draws less than 1 watt, it adds negligible thermal load to densely packed network cabinets.
