Question:
Which of the following is the most appropriate transmission frequency in optical fibre?
Which of the following is the most appropriate transmission frequency in optical fibre?
Show Hint
In optical fibre communication, the transmission frequency typically lies in the range of \(10^{14}\) Hz, which corresponds to infrared light.
Updated On: Sep 19, 2025
- \(10^9\) Hz
- \(10^{11}\) Hz
- \(10^{14}\) Hz
- \(10^4\) Hz
Hide Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Optical fibres transmit data using light, typically in the infrared or visible spectrum. The most common transmission frequencies in optical fibre communication systems are in the range of \(10^{14}\) Hz (near-infrared). This frequency is ideal for transmitting data through optical fibres due to the low loss at these frequencies.
Final Answer: \[ \boxed{\text{(3) } 10^{14} \text{ Hz}} \]
Final Answer: \[ \boxed{\text{(3) } 10^{14} \text{ Hz}} \]
