Attenuation is the loss of signal strength in networking cables or connections. This typically is measured in decibels (dB) or voltage and can occur due to a variety of factors. It may cause signals to become distorted or indiscernible.

What do we mean by attenuation?

Attenuation is a general term that refers to any reduction in the strength of a signal. Attenuation occurs with any type of signal, whether digital or analog. Sometimes called loss, attenuation is a natural consequence of signal transmission over long distances.

Is higher or lower attenuation better?

Attenuation is highly effected by frequency. If a cable works well at low speed, then it may not with higher frequencies. The greater the attenuation in a circuit, then more signal will be lost. So lower attenuation cable is always better but it comes at a price.
