摘要： In order to simplify and expedite identification of fibers (DF1/1, . . . , DF2/4) in multi-fiber cables (DF1, DF2), a method of identifying each of a plurality of fibers includes the steps of launching light into each of the fibers using an OTDR and applying a unique signature to each resulting OTDR trace by means of an event feature box comprising signature-applying means (EB) connected to a distal end of the fibers. The resulting plurality of OTDR traces have different signatures, enabling identification of each of the fibers by detecting its signature in the corresponding OTDR trace.

摘要： An OTDR device and method for characterizing one or more events in an optical fiber link are provided. A plurality of light acquisitions is performed. For each light acquisition, test light pulses are propagated in the optical fiber link and the corresponding return light signals from the optical fiber link are detected. The light acquisitions are performed under different acquisition conditions, for example using different pulsewidths or wavelengths. Parameters characterizing the event are derived using the detected return signal from at least two of the plurality of light acquisitions.
