What is the name of the communication medium where data is converted into light pulses for transmission?

Correct option is B

Optical Fiber is a communication medium that transmits data as light pulses through thin strands of glass or plastic. It is widely used for high-speed internet and long-distance communications due to its low signal loss and high bandwidth.
Important Key Points:
1. Optical fibers use total internal reflection to guide light signals.
2. They are immune to electromagnetic interference, making them suitable for sensitive applications.
3. Commonly used in telecommunication, data centers, and cable TV networks.
Knowledge Booster:
· Clad Steel: Not used for data transmission.
· Bimetallic Cable: Typically used for power applications, not data.
· Atmosphere: Refers to wireless communication mediums like radio waves, not light-based systems.
