Abstract
A system of bidirectional transmission of optical signals over an optical fiber in a telecommunications network includes a transceiver unit having an optical signal transmitter and receiver coupled with each end of the fiber, and a signal monitor for detecting a predetermined deviation in the signal strength directed toward each receiver from the fiber. This predetermined deviation is indicative of a signal path disruption in the fiber resulting in at least partial signal reflection of the signals from a transmitter toward the receiver of the same set.
