Electrical Noise

Disturbances superimposed on a useful signal that can degrade the performance of electronic equipment.

Ground Loop Circuit

An unintentional electrical loop formed when two points in an electrical system that should have the same ground reference potential do not, often leading to interference.

Fiber Optic

A technology that uses glass (or plastic) threads (fibers) to transmit data. Fiber optic cables are known for their ability to transmit large amounts of data at high speeds over long distances compared to traditional metal conductors.

Electrical Noise

Unwanted variations in an electrical signal that can degrade the performance of electronic circuits.
