Product Code : SCL-EELE-13264
Indian Lab Suppliers supplies the Fibre Optic voice transmitter and receiver trainer (Product ID: 13264) as part of its electronics engineering lab equipment range. It is a fibre optic trainer that sends audio and live voice over plastic fibre from a microphone to a speaker.
Quick Answer
A microphone feeds an audio amplifier that modulates a 660 nm LED, whose current is set by a potentiometer. The light travels through 1 m or 5 m PMMA patch cords, joined by an in-line adaptor, to a phototransistor detector driving an 8 Ω speaker. Students compare audio and voice transmission and hear how LED current and fibre length affect the received sound. A regulated 12 V and 6 V DC supply at 200 mA is built in. It runs on 230 V ±10%, 50 Hz mains with fuse and indicator lamp; use an earthed socket.
