A Gigabit Ethernet transceiver with one RJ-45 port supporting 328 ft over copper
The Transition Networks SGETF1040-110-NA is a small form-factor pluggable module that delivers 1000Base-T connectivity over copper cabling. It is designed for network administrators who need to add a Gigabit RJ-45 port to a switch or router equipped with an open SFP slot.
The transceiver measures 1.0 height by 3.3 width by 4.8 depth inches and fits standard SFP cages without tools. A single RJ-45 connector supports links up to 328 ft using Cat5e or better cable, enabling straightforward patch-panel or desk-side connections.
This module replaces a fixed copper port or a separate media converter when a fibre-ready switch needs a copper uplink. The jump is worth it when you want to reuse existing twisted-pair runs while keeping the flexibility of a modular SFP infrastructure.

The 1000Base-T RJ-45 interface supports a maximum distance of 328 ft over copper cabling.
The unit measures 1.0' Height x 3.3' Width x 4.8' Depth for stand-alone mounting.
Connect the RJ-45 port to a 1000Base-T switch and apply power; the step often missed is verifying link LEDs on both ends before assuming the link is up.
