Abstract :
A method for monitoring the quality of optical transport services is introduced. Using spread spectrum technology leads to least interferring to payload. The method´s performance and laboratory measurements are presented in this paper. This paper introduces a novel method for permanent online measurment of path characteristics. The measurement method does not interfere with the payload and also does not rely to it. It enables network providers to supervise the quality of transport through any optical transparent path.
