  • Optical-fiber environment variable apparatus, optical-fiber extracting apparatus, and optical-fiber extracting system
    Patent number: 5995701
    Abstract: To enable extraction of one specific optical fiber from a plurality of optical fibers at remote sites. An environment variable apparatus is mounted to provide a temperature difference at a predetermined position of an optical fiber. An environment variable apparatus is mounted to detect scattered light of light incident on the optical fiber through one end thereof so as to extract a target optical fiber from a large member of optical fibers. Further, synchronous devices are mounted to transmit from the environment variable apparatus to the extracting apparatus a message in that the temperature difference is given to the optical fiber, and transmit from the extracting apparatus to the environment variable apparatus a decision signal as to whether or not the optical fiber is to be extracted.
