PURPOSE: To demonstrate transmission of laser light by a real fiber optics communication line.
DESCRIPTION: One end of the fiber optics strand is held pointed into a laser beam, and the other end held by a student who is free to move about. The light emerging out the other end can easily be seen over the entire lecture hall, even when some of the cable is coiled up.
Sections of fiber optics cable are used which were left over from the installation of fiber optics cabling in underground conduits all over the University of Maryland campus. These cables are now being used for both data and video transmission.
SUGGESTIONS:
REFERENCES: (PIRA 6A44.41)
EQUIPMENT: Laser with fiber optics cables.
SETUP TIME: None.
