Which of the following is/are an example of guided transmission media?

Explanation:

Guided Transmission Media

 Guided transmission media refer to the transmission of data through a physical pathway or medium that guides the signal along a specific route. This is in contrast to unguided transmission media, where signals are transmitted through the air or space without a guiding medium. Guided media include various types of cables and fibers, each designed to carry data signals over a defined path with high efficiency and low interference.

Correct Option: Optical Fibre

Optical Fibre: Optical fibre is a type of guided transmission medium that uses light to transmit data. The fibre consists of a core surrounded by a cladding, both made of dielectric materials. The core carries the light signals, while the cladding reflects the light back into the core to prevent loss of signal. Optical fibres are highly efficient in data transmission, offering several key advantages:​

Analysis of Other Options:

Let's examine the other options provided in the question to understand why they are not examples of guided transmission media:

1. Satellite Communication: Satellite communication involves transmitting data between a ground station and a satellite in orbit. This is an example of unguided transmission media, as the signals travel through the air and space without a physical guiding medium.
2. Radio Waves: Radio waves are used for wireless communication, including radio and TV broadcasting, mobile phones, and Wi-Fi. Like satellite communication, radio waves travel through the air and do not require a physical pathway, making them part of unguided transmission media.
3. Infrared Signals: Infrared signals are used in various short-range communication applications, such as remote controls and certain types of wireless data transfer. These signals also travel through the air and are not confined to a physical medium, classifying them as unguided transmission media.
