What Is Attenuation?
Attenuation is the loss in the video signal that occurs during the transmission of analog or digital signals over a long distance. With an increase in attenuation, the signal also becomes unintelligible. One way of combating attenuation is using repeaters at regular intervals. This also reduces the speed available for transmission.
What are the causes of attenuation?
Transmission signals tend to absorb other signals in the background which reduces the intensity of the main signal.
Transmission signals which move in waves scatter when they interact with particles in a way that it removes energy which moves in the direction of propagation and diverts it into a different direction.
Attenuation also occurs due to relative humidity, temperature, improper wiring, et cetera.
Attenuation increases with the increase in the distance that it needs to travel.
What are the differences between copper vs optical cable?
Fiber optic cables are less susceptible to attenuation as it uses light as a signal. And light does not get affected by noises like electricity, radio waves, et cetera. Whereas in copper cables, the signal is transmitted in electrical frequencies, thus it can get affected by noise.
