Abstract
An OTDR calibration device based on a recirculating optical delay line has been constructed. The device operates in both passive and ‘active’ modes and in the latter mode good agreement is obtained between the measured and predicted performance of the device. The device allows calibration of OTDRs for distance, linearity and attenuation.Keywords
