Introduction
The LEOK-22 Fiber Communication Experiment Kit - Enhanced Model offers a comprehensive approach to studying fiber optic technology and provides hands-on experience with essential techniques and components commonly used in optical communication systems. This kit is designed to help students understand the fundamental principles of fiber optics while also introducing them to more advanced topics like Wavelength Division Multiplexing (WDM), Erbium-Doped Fiber Amplifiers (EDFA), and fiber-based optical switches.
By completing the experiments, students will not only grasp the theoretical aspects of fiber optics but will also gain practical skills in working with real fiber optic components and technologies. This enhanced model extends the scope of the experiments compared to the previous kits, making it an ideal choice for students interested in gaining a deeper understanding of fiber optic communication systems.
Using this kit, the following experiments can be conducted:
1. Fundamentals of fiber optics
2. Optical fiber coupling
3. Numerical aperture (NA) of a multimode fiber
4. Optical fiber transmission loss
5. M-Z optical fiber interference
6. Optical fiber temperature sensing principle
7. Optical fiber pressure sensing principle
8. Visual inspection and fault locating using OTDR
9. Optical fiber beam splitting
10. Variable optical attenuator (VOA)
11. Optical fiber isolator
12. Fiber-based optical switch
13. Wavelength division multiplexing (WDM) principle
14. Principle of EDFA (Erbium-doped fiber amplifier)
15. Transmission of analogue audio signal by laser beam in free space
16. Transmission of video signal through an optic fiber cable
