The modular fiber optics communications kit provides a complete solution to learning the key concepts of the transmission and manipulation of optical signals in modern fiber optics communication systems. it provides the students with a background in the important digital communication topics of digitization, encoding, and multiplexing. The fiber optics modular Kit is based on the concept of a Block Diagram. It is a featured solution for introducing communication technologies to the trainee for the first time. The kit consists of multiple blocks, each block represents a part of the circuit that performs an experiment.
- Module Left-hand side banana is for signal inputs (high impedance inputs).
- Module Right-hand side banana is for signal outputs (Low impedance outputs).
- Banana Marks for analog and digital signals to ease the interconnection.
- Input and outputs are protected due to mis-wiring.
- Variable controls adjustment in modules depends on the observation and measurement of output signals.
- Objectives:
- Students will gain a comprehensive knowledge of optical signals in modern fiber optic communications systems.
- Students will gain knowledge of the critical digital communication topics of digitization, encoding, and multiplication.
- Due to the engineering "modeling" nature of the trainer, students will acquire a deeper mathematical understanding of fiber optic communication systems.
