Fibre RJ45 to 1Gbit MM SC 550m set-top box

This TP-Link set-top box converts a fibre connection to a 1 Gbit Ethernet link using multimode SC connectors over distances up to 550 metres. It suits installers and network managers who need a simple media conversion point in a home or small-office video distribution system.

How it fits into a build

The unit accepts a multimode fibre feed terminated with SC connectors and presents a standard RJ45 port for copper cabling to a switch, router or set-top device. It requires an external power source and a compatible fibre patch lead, freeing the installer from running long copper runs that exceed Ethernet distance limits.

Thermals noise and power draw

The enclosure is designed for passive cooling with no moving parts, so operation is silent in normal use. Power consumption is low enough for a compact wall-wart supply, and the device runs cool enough to sit inside a standard AV cabinet without additional ventilation.
