In this video from the ICT Center, learn about fiber optic transmitters. Explore the components of a fiber optic transmitter, including a source, a modulator, an electrical driving circuit, and fiber coupling mechanics. Animations illustrate how the process of spontaneous emission converts electrical information to an optical signal in a light-emitting diode, or LED. In addition, learn about characteristics that make a source suitable for fiber optic communications.
This video is available in both English and Spanish audio, along with corresponding closed captions.
