From this kit you can perform the following experiments 1. Calculation of Power from two different lengths of Fiber cable.
a) Measurement of phototransistors current for different lengths of Fiber cable.
b) Calculation of launch power for each light source.
c) Calculation of attenuation coefficients (a) of fiber, for different light sources, 2. Measurement of Rise and fall time for various detectors and light sources.
a) Measurement and calculation to determine which light source and detector combination is faster.
b) Measurement and calculation to determine upper frequency 3dB Bandwidth, for different light sources.
c) Measurement and calculation to determine upper frequency 3dB Bandwidth, for different detectors. 3. Comparisons of the Transmission characteristic of a continuous Fiber cable Vs those with spliced cables. 4. Study of Index matching with splices includes,
a) Measurements of phototransistor current when Fibers are spliced together with and without index-matching, Comparison of the transmission characteristics of a Fiber splice with and without index matching includes calculation of Fresnel’s reflection. This unit is assembled in an ergonomically designed cabinet, with necessary power supplies and associated emitters, detectors, multi mode transmission cables. You need optional signal sources, Oscilloscope, a high impedance mulitmeter as additional equipment to successfully conducting the above objectives. Specification: Types of Transmitters:-
