The Attenuation-Wavelength Curve and the
Transmission Windows of an Optical Fibre.
Infrared Light with Wavelengths of 850 nm, 1,310 nm and 1,550 nm
is mostly used. Therefore, the most common devices used as the
Light Source in Optical Transmitters are the Light Emitting Diode
(LED) and the Laser Diode (LD). They operate in the Infrared
Radiation (750nm to 1mm) of the Electromagnetic Spectrum so that
their Light Output is usually invisible to the human eye.
