Product Detail

Product Tags

Note: oscilloscope not included


This covers kit fiber optic technology and can practice the students’ skill of operating fiber optics. It covers 14 experiments in fiber optics and photonics, it’s designed with all separate parts for the students to assemble, such as WDM and coupling. Student can understand the characteristics of isolators, attenuators, optical switches, transmitters, amplifiers etc.


Students can have a better understanding of fiber optic fundamentals with operating experience in real fiber optic components and techniques. This kit is the best choice for those wishing to learn fiber optics with related techniques.
