What is an 'Extender'?
An 'Extender' is a device used to extend audio/video signals and cables over a longer distance. It is commonly referred to as an 'active extension cable' because it typically includes a built-in signal amplifier to reduce signal loss caused by the extended cable length. Common types of extenders include VGA extenders, D-SUB extenders, HDMI extenders, USB extenders, KVM extenders, and computer extenders.
