Product Description

The Bytronic AFOT Fibre Optic Communication trainer provides a full duplex method of transmitting information from one place to another by sending pulses of light through an optical fibre, the light forms an electromagnetic wave that is modulated to carry information. The advanced fibre optics communication trainer is designed to learn the communication techniques in Fibre Optics.

The trainer demonstrates properties of Fibre Optics Transmitter and Receiver, characteristics of Fibre Optic cable, different types of Modulation/Demodulation techniques via fibre link. It can also be used to demonstrate various digital communication techniques.
