Attenuation Effects on Data Transmitted through Cable Abstract Attenuation refers to any reduction in the strength of a signal. Attenuation occurs with digital or analog signals. Attenuation is the end result of signals being transmitted extended distances. Attenuation is usually expressed in units called decibels (dBs). The cable type will determine at what point along the length of the cable signal degradation occurs. Repeaters can be inserted along the length of the cable to boost
