Any electrical component that is independently powered
Electronics components, such as transistors, diodes, electron tubes, thyristors, etc which can operate on an applied electrical signal as to change its basic characteristics ie: rectification, amplification, switching, etc.
Semiconductor and networking components that require external power in order to function and respond to input, as opposed to a passive component, which needs no external power.
Active components of a die are transistors and diodes.
Semiconductor devices, such as transistors and diodes, that can change its basic characteristics in an powered electrical circuit, such as amplifiers and rectifiers.
Electronic components such as semiconductors, transistors, diodes, etc., that can operate on an applied electrical signal and change its basic characteristics (e.g., switching, amplification, rectification).
Optical components that are defined by the need for electrical power to generate, boost, or transform optical signals. Active components consist of source lasers, pump lasers, detectors, modulators, and optical switches.
devices based on semiconductor laser technology that provide the light in a fiber optic network. They require the integration of electronics and wiring into a package using traditional assembly technologies. Receivers, transmitters, modulators, amplifiers and switches are examples of active components. These devices are generally easier to assemble than passive components.
