Question:
Attenuation in optical fibre can be measured in:
Attenuation in optical fibre can be measured in:
Show Hint
In optical fibre, attenuation is the reduction in signal strength, typically expressed in dB per meter.
Updated On: Sep 19, 2025
- KdB/m
- dB/m
- dB/km
- dB/mm
Hide Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Attenuation in optical fibres is typically expressed in decibels per meter (dB/m). This represents the loss of signal strength per unit length as the signal travels through the fibre.
While other units such as dB/km and dB/mm can be used in different contexts, dB/m is the most commonly used unit in practical applications.
Final Answer: \[ \boxed{\text{(2) dB/m}} \]
