Standalone Gigabit Fiber Converter

The TRENDnet TFC-GMSC is a standalone media converter that bridges 10/100/1000 Mbps copper Ethernet to 100/1000 Mbps multi-mode fiber. It serves network installers and IT teams who need to extend a Gigabit link beyond the reach of standard twisted-pair cabling.

Multi-Mode Distance Limit

The SC-type fiber port operates at an 850 nm wavelength and supports links up to 550 m (1800 ft.) on multi-mode fiber. Copper connectivity is provided by an Auto-MDIX RJ-45 port compliant with IEEE 802.3, 802.3u, 802.3ab, 802.3z and 802.3x standards.

2 Gbps Switching Capacity

The converter delivers a total switching capacity of 2 Gbps, enabling full-duplex Gigabit throughput across both ports. This single figure determines whether the unit can sustain line-rate traffic for the intended deployment.

Questions about this item

Which model should I choose for multi-mode SC fiber up to 550 m?

The TFC-GMSC is the single model listed; it provides one 10/100/1000 Mbps Auto-MDIX copper port and one 100/1000 Mbps SC-type multi-mode fiber port for distances up to 550 m.

What does the 2000 Mbps switching capacity mean in daily use?

It indicates full-duplex Gigabit throughput — 1000 Mbps each way simultaneously — so the converter can pass line-rate traffic without bottleneck.

How does the 850 nm multi-mode SC interface limit real-world distance?

The 850 nm wavelength on multi-mode fiber caps the practical link at 550 m (1800 ft.), matching the converter’s rated maximum.
