Question

In an optical fibre during transmission of light

• A. Energy increases.
• B. Energy decreases.
• C. No loss of propagation of energy takes place.
• D. Light partially reflects and refracts.

Answer 1

The correct option is C No loss of propagation of energy takes place.

Attenuation is a gradual loss int he intensity of any kind of flux through a medium .in telecommunication the attenuation affect the propagation of waves and signals. so during transmission of light through an optical fiber optical and electrical attenuators cause the loss in transmission.
