Description
Laser Diode Intensity Modulation and Demodulation Trainer has been developed to conduct studies on laser Diode, optical fibres and optical communication methods, by signal transmission. Practical experience on this Trainer carries great educative value for Science & Engineering Students.
Experiments: Characterisation of a Laser Diode :
- Optical Power (Po) of a Laser Diode Vs Laser Diode Forward current (I).F
- Monitor Photodiode Current (I ) Vs Laser Optical Power Output (Po). M
Design and Evaluation of an Laser Diode (LD) Analog I System M :
- Vo Vs Vin at Specified Optical Carrier Power Levels, Po
- Determination of Vin (max) at Specified Po for Distortion-free Vo
Design and Evaluation of Laser Diode LD Digital Transmission System :
- Risetime and Falltime Pulse width Distortions and Determination of Propogation Delay
Transmission of Laser through an Optical Fibre :
- To measure loss in dB of Step-index Multimode plastic Fibre Patchcord
- To measure loss in dB of Graded-Index, Multimode Glass Fibre Patchcord
- To measure loss in dB of Two Patchcords connected by the in-line Adaptor
