Attenuation refers to the loss of ___________.
Attenuation refers to the loss of Energy.
Attenuation is a general term that refers to any reduction in the strength of a signal. Sometimes called loss, attenuation is a natural consequence of signal transmission over long distances. The extent of attenuation is usually expressed in units called decibels (dBs).
Attenuation in fiber optics, also known as transmission loss, is the reduction in intensity of the light beam (or signal) with respect to distance travelled through a transmission medium.
Transmission medium - All electrical signals transmitted down electrical conductors cause an electromagnetic field around the transmission. Crosstalk from adjacent cabling causes attenuation in copper or other conductive metal cabling.
