Fiber Optics Trainer

	Fiber Optics Trainer Model ABVOLT-FOT1 is designed to learn the basics of Fiber Optics. The trainer demonstrates properties of Fiber Optic Transmitter & Receiver, Characteristics of Fiber Optic Cable and different types of Modulation/Demodulation techniques. A large number of experiments are included in the workbook and many more can be performed using the trainer. The trainer can also be used to demonstrate various digitals Communication techniques via Fiber Optic link using other Digital communication Trainer.

• Simplex Analog & Digital Trans Receiver.
• Single Module covering large number of experiments including
• experiments with optical power meter (optional).
• 660 nm channel with Transmitter & Receiver.
• AM - FM - PWM Modulation/Demodulation.
• On-board Function Generator, Crystal Controlled dock & in built DC power supply
• Functional blocks indicated on-board mimic with input/output & test points.
