Fibre Optic Voice Transmitter and Receiver Trainer
Product Code : JA-FOT-1541
The Fibre Optic Voice Transmitter and Receiver Trainer sends audio and speech over plastic optical fibre: a microphone feeds an audio amplifier and a 660 nm fibre-optic transmitter, and a phototransistor detector drives an 8 ohm speaker at the far end. It is used for experiments on fibre-optic transmission of audio and voice signals (SKU JA-FOT-1541).
