Chapter 20: Problem 2724

What type of medium is used in optical communication? (A) guided medium (B) Unguided medium (C) Both guided and unguided media (D) Neither guided nor unguided media

Short Answer

Expert verified
In optical communication, light signals are transmitted through fiber optic cables, which are thin strands of glass or plastic that guide the light over long distances. Therefore, the type of medium used in optical communication is (A) guided medium.

Step by step solution

01

Understanding Optical Communication

Optical communication is a type of communication that utilizes light to transmit data from a transmitter to a receiver. It involves the use of fiber optic cables, which are thin strands of glass or plastic that can carry light signals over long distances. The signals are then converted back to electrical signals at the receiver end.
02

Identifying the Type of Medium

Since optical communication uses fiber optic cables to transmit light signals, it can be classified as a guided medium. Guided media are those in which the transmission of data is contained and guided through a physical pathway. In the case of optical communication, light signals are guided through the fiber optic cables. The correct answer is: (A) guided medium
