Abstract :
A new method of detecting fibre breaks in a passive optical subscriber network without interruption to nonaffected customers is demonstrated. For these live measurements, an optical frequency domain reflectometry technique (OFDR) is used. No separate wavelength or additional components in the network are required. An integration facility on the AM/VSB TV-transmission system, without affecting TV-picture quality, is realised.
