Network Mode Converter

The Tripp Lite N784-MDC-4STST converts multimode fiber signals to singlemode for extended network reach. It operates at 100 Mbps with a 1310 nm wavelength. Network engineers use it to bridge connections between hubs and switches across long distances. The unit is built for commercial environments requiring reliable fiber extension.

Diagnostic LEDs and Metal Housing

Side-mounted LEDs display link status, signal diagnostics, and power state for immediate troubleshooting. They alert technicians when a fiber cable is severed or service is disrupted. A rugged metal enclosure protects internal components. The housing is rated for continuous operation from 0 to 70 degrees Celsius.

40 Kilometre Reach at 100 Mbps

The converter extends network links up to 40 kilometres (24.9 miles) over singlemode fiber using ST connectors. It handles standard Fast Ethernet traffic within that distance. Bandwidth is fixed at 100 Mbps, so gigabit or higher throughput needs are not met. Buyers requiring multi-gigabit speeds or different connector types must select another device.

Questions about this item

Will the ST connectors or fiber patch cords need periodic replacement as the link ages?

The converter uses fixed ST connectors on the metal housing; only the external patch cords may need replacement if they become damaged or contaminated.

What limits continuous throughput when the link runs at full 100 Mbps over 40 km?

The 100 Mbps transfer rate and 1310 nm singlemode path set the bandwidth ceiling; the converter itself does not impose a lower sustained limit.

How much heat does the metal box produce when powered 24/7 at 70 °C ambient?

The rugged metal housing is rated for 0 to 70 °C operation with no fan, so heat output stays within passive cooling limits at full load.
