Question

Band width of an optical fiber is

• A. More than 100 GHz
• B. 100 GHz
• C. Less than 1 MHz
• D. 1 MHz

Hint:

Optical fibers provide higher bandwidths than most other transmission media, making them ideal for high-speed data transmission in telecommunications and networking.

Answer 1

The Correct Option is A

The band width of an optical fiber is typically more than 100 GHz. Optical fibers can transmit data over a wide frequency range, which allows them to carry large amounts of data with minimal loss. This high bandwidth capability is one of the key advantages of optical fibers over traditional copper cables.

Answer 2

Step 1: Understanding Bandwidth in Optical Fibers
Bandwidth of an optical fiber refers to the range of frequencies that can be transmitted through the fiber without significant loss or distortion.

Step 2: Significance of High Bandwidth
High bandwidth allows optical fibers to carry large amounts of data at very high speeds, making them ideal for modern communication systems.

Step 3: Typical Bandwidth Values
Optical fibers generally have bandwidths exceeding 100 GHz, which is significantly higher than conventional copper cables.

Step 4: Conclusion
Therefore, the bandwidth of an optical fiber is more than 100 GHz.
