FO2 1  FO2 2


  • The low-priced Basic Fiber Optics Kit comprising three components, namely an SMA connectorised 660 nm, FO LED, a matching phototransistor and an SMA-connectorised one-meter optical fiber PMMA fiber patch cord, Analogue Transceiver Module to transmit and receive analogue voltage signals via the optical fiber medium.
  • This trainer is supplied as a fully assembled and tested, single-sided glass epoxy printed circuit board (PCB).
  • To make the system operational, an internal regulated dual power supply +5 Vdc +9 Vdc and a signal source are provided.
  • An oscilloscope/DMM will be required to study the signals. Some components have been provided to facilitate easy change, by the user, to achieve desired performances and to take measurements.
  • Through minor alterations in the circuit, change of ICs and increase in cable length, a bandwidth in excess of 100 KHz and distances over 20 meters can be achieved.

Features of the Trainer

  Power supply     

Voltage range : AC 100V - 230 V

Frequency range : 50 - 60Hz

Housing It is mounted in an elegant ABS Plastic cabinet for better viewing and portability
Dimension 29cm x 20cm x 11cm (each)
Weight 1.5kgs (each)

This trainer is a glass-epoxy printed circuit board and all the symbols screen-printed on the front panel so that it enables the student to conduct the experiments easily


  • 2mm multi coloured moulded patch cords with daisying facility.
  • Step-By-Step detailed instructions are provided with the instruction manual.
  • Fiber optic cable terminated with SMA connectors - 1 meter.


  • Lab Electronics offer a professional FO Kit, (850nm on multimode GI fibers) for large bandwidth and low loss designs.
  • The realisation of a FO analogue transmission trainer using Fiber-optic cable is shown. The optical output from the LED is looped back to the detector via the PMMA patch cord some of the studies one can carry out on the trainer are:
  • Characteristics of the FO LED (ILED vs PO ILED vs Vf)
  • Characteristics of FO photodetector (PO vs IP, lark)
  • System bandwidth and linearity
  • Attenuation and numerical aperture of the PMMA fiber.
  • Trainer comes with fully assembled and tested, single sided glass epoxy PCB with sloping fiber cabinet for better viewing. Test points are provided for measurement and springs are provided for patching the circuit.
