Fiber Optic Communication Trainer

his trainer uses LEDs in visible range (660 nM) as transmitter, fast PIN-Photodiodes as receiver. A Plastic Optic Fiber (POF) is used as the channel connecting light signal from the transmitter to the receiver. Each of the transmitter and receiver are placed in a PCB mountable plastic housing. A 2.2 mm aperture is provided to hold standard 1000 micron POF. No fiber stripping is required. Microlens is a part of the housing.Sine and triangular signal source with variable frequency and amplitude.A switch to select sine or triangular signal and connect to the transmitting circuit.A variable POT at the transmitter offers the intensity adjustment.A switch is provided to select the Optical receiver to be connected either to the power measurement circuit or to the signal receive and regeneration circuit.Built in 3 12 digit display for measuring optical power in DB.
