Fiber-Optic Transmission Trainer

Fiber-Optic communication is one of the most popular technologies in the modern days due to its high transfer speed and large capacity. It uses fiber optic as a transmission media for the whole experiment. With four different data 2transmission ways (self-module transmission, module-to-module transmission, PC- to-module transmission and module-to-PC transmissions) and various different modulation / demodulation methods (CVSD, ASK, etc.) introduced in the training system, users can obtain a very clear view of how fiber-optic transmission works. With four different data transmission ways (self-module transmission, module-to- module transmission, PC-to-module transmission, and module-to-PC transmission). The experiment of trainer shows you how easy it is to make productive use of fiber optic materials. The equipment that you assemble will transmit voice from one point to another, using light traveling through an optical fiber.
