Copper SFP for switch upgrades

This TRENDnet TEG-MGBRJ module converts an SFP slot into a 1000BASE-T RJ-45 port, adding copper gigabit connectivity to switches and media converters. It targets network administrators who need extra copper ports without buying new hardware and supports data rates up to 1.25Gbps over standard twisted-pair cabling.

Thermals and power in normal use

The transceiver operates within standard SFP power envelopes and produces no audible noise because it has no moving parts. Heat output stays low enough for dense switch chassis, and the hot-pluggable design allows insertion or removal without powering down the host device, keeping rack uptime intact.

Build quality and daily connectors

An RJ-45 jack accepts Cat5e or better patch cables up to 100m (328 ft.) per IEEE 802.3ab, while the MSA-compliant SFP housing ensures a secure fit in multi-vendor equipment. The compact module weighs .3570 units and carries a lifetime manufacturer warranty, so spare units can be kept on hand for quick field swaps.

Questions about this item

How do I install the TEG-MGBRJ into an SFP slot without damaging the latch?

Power off the switch, slide the module straight in until the latch clicks, then connect the Cat5e or better cable to the RJ-45 port; the hot-pluggable design allows insertion without a full reboot but the latch must engage fully or the link will flap.

What maintenance or replacement will the TEG-MGBRJ need over time?

The module has no moving parts or user-serviceable components; keep the RJ-45 port dust-free and reseat the transceiver if link errors appear after years of vibration or temperature cycling.

What limit appears first when the TEG-MGBRJ runs at full 1.25Gbps continuously?

The 100 m (328 ft) copper reach defined by IEEE 802.3ab is the first hard bound; signal degradation beyond that distance causes errors before any thermal or power ceiling is reached.
