Infrared Communications refers to optoelectronic components and modules that transmit and receive data using infrared (IR) light as the communication medium. This category typically includes IR emitters and IR detectors, as well as integrated devices that combine optical transmission and reception functions.

These products enable short-range, line-of-sight optical signaling by converting electrical signals into infrared radiation and converting received infrared light back into electrical signals. Infrared communication devices are commonly designed to support standardized IR signaling methods and are used where wireless data exchange is required without using radio-frequency transmission.

• Core function: Optical data transmission and reception using infrared light
• Key elements: Infrared light sources, infrared sensing elements, and related signal interface circuitry
