Advantages of optical fibre communications over two wire transmission line or co-axial cable transmission are
Updated On: Apr 30, 2024
- low band width, low transmission loss
- high band width, high transmission loss
- high band width, low transmission loss
- low band width, high transmission loss
Hide Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
In optical conununication, light is transmitted in the form of light puises along an opticaI fibre as transmission medium. Since, wavelength of the light is very small, it provides a very large band width and can carry a huge amount of information. And main merits of two wire transmission line or co-axial cable transmission are that they are quite cheap, very easy to install and less electrical disturbances (noise).
So, the required answer is high band width and low transmission loss.
So, the required answer is high band width and low transmission loss.

Concepts Used:
Communication Systems
A system that describes the information exchange between two points is called the communication system. The transmission and reception process of information is called communication. The major elements of communication are such as:
- The Transmitter of information
- Channel or medium of communication
- The Receiver of information
Examples Of Communication Systems:
The following are the examples of communication systems:
- Internet
- Public Switched Telephone network
- Intranet and Extranet
- Television
Types Of Communication Systems:
Turning on Signal specification or technology, the communication system is categorized as follows:
- Analog technology communicates data as electronic signals of differing frequencies or amplitude. For instance Broadcast and telephone transmission.
- In Digital technology, the data are created and processed in two states: High (represented as 1) and Low (represented as 0). Also this technology stores and transmits data in the form of 1's and 0's.
