LEOK-21 Fiber Communication Experiment Kit - Complete Model

Features

  • Covering 11 experiments in fiber optics

  • Flexible solution for different level of students

  • Detailed instruction manual






Introduction

Optical fiber has increased signal transmission bandwidth over longer distance. As the importance of fiber rises, numerous colleges and universities worldwide introduce more courses in optoelectronics and optical communications. This kit is designed to meet the increasing demand for learning fiber optic fundamentals and enhancing related practical skills. This Fiber Optic Experimental kit is a sister kit to LEOK-20, and is revised and rewritten to include new experiments such as to measure the parameters of optical fiber beam splitter, attenuator and isolator.

 

Using this kit, the following experiments can be conducted:


1) Fundamental knowledge of optical fiber optics
2) Coupling method between optical fiber and light source
3) Multimode fiber numerical aperture (NA) measurement
4) Optical fiber transmission loss property and measurement
5) M-Z optical fiber interference
6) Optical fiber thermal-sensing principle
7) Optical fiber pressure-sensing principle
8) Visual inspection and fault locating using OTDR

9) Optical fiber beam splitter parameter measurement
10) Variable optical attenuator and parameter measurement
11) Fiber optic isolator and parameter measurement
