Filed: 2002-11-06
Abstract: <P>PROBLEM TO BE SOLVED: To provide a method for determining the presence or the absence of a loss point which can prevent the loss point from sticking by determining the presence or the absence of the loss point, and a distributed Raman amplifier using the same.  <P>SOLUTION: The method for determining the presence or the absence of the loss point determines the presence or the absence of the loss point in a light transmission line by the distributed Raman amplifier which amplifies signal light by making the light transmission line as an amplification medium by making excitation light incident in the light transmission line to transmit the signal light in the direction opposite to the signal light. Scattered light separated from the light transmission line is monitored. A part of the excitation light is separated and monitored. Reflected light advancing in the direction opposite to the excitation light is separated from the light transmission line and monitored. When monitored excitation light power becomes a prescribed determination value, the presence or the absence of the loss point is determined on the basis of a ratio of the monitored scattered light power and the monitored reflected light power.  <P>COPYRIGHT: (C)2004,JPO
