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.
Here are suggested ways to engage students with this video and with activities related to this topic.
Academic standards correlations on Teachers' Domain use the Achievement Standards Network (ASN) database of state and national standards, provided to NSDL projects courtesy of JES & Co.
We assign reference terms to each statement within a standards document and to each media resource, and correlations are based upon matches of these terms for a given grade band. If a particular standards document of interest to you is not displayed yet, it most likely has not yet been processed by ASN or by Teachers' Domain. We will be adding social studies and arts correlations over the coming year, and also will be increasing the specificity of alignment.
