This Kit allows you to send sound through 1mm plastic fibre optic (FO) cable. On the transmitter (Tx) circuit board (marker KIT 26T) there is a microphone and a circuit to modulate the light emitted from an LED. The LED is contained in a plastic case, which allows easy connection of the FO cable. On the receiver (Rx) board (marked KIT26R) there is the photo-darlington receiver unit, a speaker and a circuit to convert and amplify the detected signal back into a sound wave. Because the signal travels in the FO cable as a light wave it is unaffected by any electric or magnetic fields that it travels through. Each board requires a 9V battery. However, for continuous use plug packs would be advised. Fourteen feet of 1mm diameter plastic (FO) cable is supplied. This Kit can be used to send a signal in well over 200 yards of cable. Note that the plastic FO cable used here is not the glass 1-micron FO cable, which is used in long distance (say 20 miles) communications. However, plastic cable introduces most FO concepts, is far easier for the experimenter to use and certainly has definite uses for short distance communication in electrically noisy environments. The kit is constructed on a single-sided printed circuit board (PCB). Protel Autotrax and Schematic were used to design the board.
