Definition of "Infrared Light" |
Infrared light is electromagnetic radiation with longer wavelengths than those of visible light, extending from the nominal red edge of the visible spectrum at 700 nanometers to 1 mm. This range of wavelengths corresponds to a frequency range of approximately 430 THz down to 300 GHz. Most of the thermal radiation emitted by objects near room temperature is infrared. / Attenuation-to-Crosstalk Ratio is a parameter that is measured when testing a communication link, which represents the overall performance of the cable. |
