Advanced Optical Fiber Communication

Description

Scientech 2502A Advance Fiber Optic Communication demonstrates Full Duplex method of transmitting
information from one place to another by sending pulses of light through an Optical fiber. The light forms
electromagnetic wave that is modulated to carry information. Scientech 2502A is an Advanced Fiber Optic
designed to learn the communication techniques in Fiber Optics. The 2502A demonstrates properties of Fiber
Optics Transmitter & Receiver, characteristics of Fiber Optics Cable, different types of Modulation / Demodulation
techniques and PC to PC communication via fiber link using USB interface. It can also be used to demonstrate
various Digital Communication Techniques via Fiber Optic link using Scientech Digital Communication. Study of
Eye pattern and experiment of BER measurement can be perform in conjuction with addon module.
