  • Methods for intercepting optical fiber signals

    Methods for intercepting optical fiber signals

    There are a number of known methods of extracting or injecting information into a fiber link, while avoiding detection. In this paper we highlight a number of known fiber tapping. A system is provided for intercepting signals transmitted between a target served by a fiber optic network and a subscriber. A network is described having a phone switch at a central office configured to receive signals for transmission to and from a target, such as the target of a criminal. Fiber tapping is a network tap method that extracts signal from an optical fiber without breaking the connection. Fiber to the home (FTTH) systems use beam. In the mid-1980s, I (JH) submitted a paper to a military fiber optics conference that covered how to tap fiber, how to detect it was being tapped and how to secure communications in fiber in case it was tapped. the paper was classified and until it was declassified around 2005, was not discussed.
