This trainer is intended to study the analog data transmission principles. Although most fiber optic systems are digital in format, there are few analog applications. Designing an LED / LASER driver for an analog fiber optic system is comparable to designing an electronics CLASS-A amplifier. It must have adequate bandwidth, good linearity, and non-clip for the range of input signals. This trainer provides a means to study and experiment how an analog signal can be transmitted over a multimode 1000 mm multi-mode plastic fiber cable. Study of Fiber Transmission circuits includes, and Calculation of 3dB bandwidth. This trainer includes an analog transmitter, transmitting media, and a receiver. The analog transmitter consists of an LED (680 nm) / IR emitter (800nm) as an optical driver. The transmission media is 1000 mm multi-mode plastic fiber cable. The receiver consists of a linear amplifier. This unit is assembled in an ergonomically designed cabinet, with necessary power supplies and associated emitters, detectors, multi mode transmission cables. You need an optional signal source, Oscilloscope, a high impedance mulitmeter as additional equipment to successfully conducting the above objectives. Specification: Types of Transmitters:-
