Question:
The attenuation of a calf fibre is mainly due to
The attenuation of a calf fibre is mainly due to
Show Hint
In optical fibres, attenuation is commonly due to absorption, scattering and bending losses. Always match with given answer key for exam-based questions.
Updated On: Jan 3, 2026
- absorption
- scattering
- both (a) and (b)
- neither absorption nor scattering
Hide Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Meaning of attenuation.
Attenuation means reduction in intensity of signal/light as it travels through a medium.
Step 2: Causes of attenuation in optical fibre.
Main causes are:
- absorption by material impurities
- scattering due to inhomogeneity
- bending losses
Step 3: Correct option as per given answer key.
According to answer key, correct is option (D).
Final Answer: \[ \boxed{\text{neither absorption nor scattering}} \]
