Data sheet Modulable 650 nm laser + fiber transmission study set

Description

This « Sound optical transmission » kit is a comprehensive data transmission chain.

Demonstrative and easy to implement, it allows making the sound transmission by light concrete.

The optical transmission of a signal is ensured by a modular, intensity and focusing adjustable laser. The application purpose of the experiment passes through the measurement of the bandwidth, the digital opening, the permissible amplitude...

Three methods of use are available: in the air, by optical fiber with and without connectors.

Experiments:
- Digital opening
- Transmission: bandwidth, modulated signal and attenuation
- Spectral attenuation of a fiber
- Wavelength multiplexing

The free space and guided propagation principles are outlined via the use or non-use of the 2 m provided optical fiber.

To progress further, the signals can be processed using a function generator and an oscilloscope.

Hint: the adjustable/modular laser provided in this kit can be used for all handlings requiring a laser, namely for the diffraction and interferences.
