Abstract: Zur Lokalisierung der Inhomogenitaeten und insbesondere von Bruechen ist es bereits bekannt, das Verfahren der Impulsreflektometrie aus der Mikrowellen- und Nachrichtentechnik zu uebernehmen. Bei einer bekannten Messvorrichtung besteht das Problem der Fehlerortung darin, moeglichst viel Licht in den Lichtleiter einzukoppeln, um auch unguenstige Brueche noch lokalisieren zu koennen. Dabei entstehen jedoch hohe Uebertragungsverluste durch das Einkopplungslinsensystem sowie das Auskopplungslinsensystem, so dass eine erhebliche Schwaechung des Messignals auftritt, wodurch das Auffinden der Fehlerstellen stark beeintraechtigt werden kann. Die vorgeschlagene Vorrichtung besteht aus einem Strahlungsteiler zur Aufteilung eines Eingangslichtsignals eines Lasers in zwei Teilsignale und einem Fotodetektor zum Empfang eines Teilsignals. Aufgrund dieser Ausgestaltung entfallen jegliche Linsensysteme zur Fokussierung des Laserlichtstrahles, wodurch die gesamte Messvorrichtung wesentlich vereinfacht wird. Weiterhin wird eine weitgehende Reduzierung der Uebertragungsverluste erreicht, denn die Uebertragungswege der Signale innerhalb der Messvorrichtung koennen aeusserst kurz gehalten werden. Es entfallen auch die sonst ueblichen schwierigen Justiermassnahmen, insbesondere beim Anschluss der zu messenden Lichtleitfaser, da durch das Ankoppeln ueber einen Stecker automatisch eine mechanische Justierung erfolgt, die beliebig reproduzierbar ist.                                        ...U.S.W
