Receiver for Fibre-Optic IR Extender

Published in issue 290, July 2000

There are various types of remote-control extenders. Many of them use an electrical or electromagnetic link to carry the signal from one room to the next. Here we use a fibre-optic cable. The advantage of this is that the thin fibre-optic cable is easier to hide than a 75-? coaxial cable, for example. An optical link also does not generate any additional radiation or broadcast interference signals to the surroundings.
