Reporting Category: Electrical and Communication Systems Standard: 6.4 - Identify and explain the applications of laser and fiber optic technologies (e.g., telephone systems, cable television, and photography).
The illustration below shows three major components of a fiberoptic cable.
Describe the function of the core and the function of the cladding.
In recent years, fiberoptic cable has been replacing copper wire as a means of transmitting communication signals.
Describe the difference between the signals that are transmitted by fiberoptic cable and those transmitted by copper wire.
The core in a fiberoptic cable can be made of plastic or glass.
Identify two advantages of using plastic instead of glass in a fiberoptic cable.
Scoring Guide and Sample Student Work Select a score point in the table below to view the sample student response.
Response demonstrates a thorough understanding of fiberoptic technologies. The response correctly describes the functions of the core and the cladding of a fiberoptic cable, correctly describes the difference between signals transmitted by a fiberoptic cable and signals transmitted by a copper wire, and correctly identifies two advantages of using plastic instead of glass in a fiberoptic cable.
