Advanced Fibre Optic Trainer-Dual Channel & PC-PC Communication Facility

Fibre Optics as a new transmission medium has revolutionized the telecom industry. It has numerous advantages over traditional wired or wireless transmission systems. Thus study of Fibre Optic communication systems has become more important. Advanced Fibre Optics Trainer is designed to learn the communication techniques in Fibre Optics. The trainer demonstrates the properties of Fibre Optics Transmitter and receiver, characteristics of Fibre Optics Cable, different types of Modulation / Demodulation techniques and PC-to-PC communication via fibre link using an RS232 interface. It can also be used to demonstrate various Digital Communication Techniques via Fibre Optic link using Digital Communication Trainers.
