VORRICHTUNG ZUR ERFASSUNG DER PMD VON OPTOELEKTRONISCHEN ÜBERTRAGUNGSSTRECKEN

摘要

The invention relates to a device for detecting the PMD of optoelectronic transmission lines. The inventive device is characterized in that it comprises a narrow-band, tunable laser, whose illumination is superimposed with the illumination of the transmission line to be analyzed and an optoelectronic heterodyne receiver which receives the superimposed signal.
