TRENDnet TEG-MGBRJ 1000BASE-T RJ-45 Copper SFP Module data converter

SKU CH-ZX4S-N3N3X

Converts an SFP slot to a 1000BASE-T RJ-45 copper port reaching 100 m (328 ft) at 1.25 Gbps

  • Converts SFP slot to RJ-45 gigabit copper port
  • Supports data rates up to 1.25Gbps
  • Transmission distance up to 100m (328 ft)
  • Hot-pluggable for easy installation without power down
  • IEEE 802.3ab compliant for Gigabit Ethernet networks

Converts SFP Slot to RJ-45 Gigabit Port

This module turns an available SFP slot on a network switch or media converter into a standard RJ-45 gigabit connection. It is designed for administrators who need additional copper links without buying extra switches. The unit complies with IEEE 802.3ab and MSA standards for broad equipment compatibility. Installation is hot-pluggable, so the host device stays online during insertion.

Runs Continuously Within Rated Distance

The transceiver maintains gigabit throughput over copper cable runs up to 100 metres or 328 feet. It supports data rates up to 1.25 gigabits per second under sustained load without thermal throttling. Lifetime manufacturer protection covers the module for its entire service life. No active cooling is required because power draw stays within SFP slot limits.

Hot-Pluggable Insertion Avoids Downtime

Simply slide the module into any MSA-compliant SFP cage until it clicks, then connect a standard patch cable. The only common issue occurs when the host port is configured for fibre-only operation, which prevents link negotiation. A quick installation guide is included for first-time deployments. Verify switch firmware supports copper SFP modules before purchase.

Questions about this item

How much power does the TEG-MGBRJ draw when running continuously?

The module operates within standard SFP power limits for 1000BASE-T copper transceivers, so heat and noise stay negligible inside a ventilated switch chassis.

What must I already have for this TEG-MGBRJ to work?

You need a switch or media converter with an MSA-compliant SFP slot that supports 1000BASE-T RJ-45 copper signalling.

Will the TEG-MGBRJ link at gigabit speed with my older Cat5e patch cables?

Yes, it supports IEEE 802.3ab up to 100 m (328 ft) over Cat5e or better copper cabling.
