Gigabit Ethernet to Fibre Converter

The Tripp Lite N785-001-LC-MM bridges a copper RJ45 link to LC duplex multimode fibre, extending a 10/100/1000 network up to 550 metres at 850 nm. It suits installers who need to span distances beyond the reach of standard twisted-pair cabling in commercial or campus environments.

Compact Metal Enclosure with External Supply

A small, rugged housing carries six status LEDs for link, speed and duplex monitoring on both ports. The converter ships with a 100–240 V AC adapter delivering 5 V at 1.2 A via a NEMA 1-15P plug, so it powers from any standard mains socket without occupying a switch chassis slot.

Passive Cooling for Silent Operation

No internal fan is fitted; the unit dissipates its low power draw through the metal case, yielding silent running in office or rack settings. Auto-negotiation handles MDI/MDI-X and full or half duplex modes automatically, keeping the link stable without manual configuration or additional heat-generating circuitry.

Questions about this item

What distance does the 850 nm multimode interface support on 50/125 µm fiber?

The converter extends a Gigabit Ethernet signal up to 550 meters (1800 ft) over 50/125 µm multimode fiber at 850 nm wavelength.

What connectors and power supply are required to install the unit?

One RJ45 port for copper, one LC duplex port for fiber, and the included external 5 V 1.2 A power adapter with a NEMA 1-15P plug.

How is the converter powered up and what common step is missed?

Connect the external power adapter to the converter first, then plug it into a 100-240 V outlet; the six LEDs will confirm link and power status.
