AUDIO TRANSMISSION BY FIBER OPTICS

Educational content :

• Signal transmission
• Fiber optics
• Modulation
• Bandwidth
• Attenuation

This complete process of optical signal transmission uses fiber optics.

An audio signal will be used as the information to transmit.

This practical deals with all aspects of a real system: Injection, numerical aperture, signal transmission, bandwidth, fiber absorption…
