Zusammenfassung:The measured fibre has reference fibres connected to each end. Reflected power is measured from either end of the combined fibre circuit and the reflected powers in decibels are plotted against distance along the circuit. The difference in power level between corresponding points (A1,B2) for measurements made in one sense is compared with a corresponding difference measured in the opposite sense. If the two differences are equal the measurements made are valid
