Abstract

In this work, the development of a hybrid structure for the monitoring of optical fibers, using two types of Photon Counting Optical Time Domain Reflectometers (n-OTDR), is presented. While one n-OTDR presents a 32 dB dynamic range with spatial resolution of 6 m and minute-range measurements, the other has a 14 dB dynamic range and a resolution of 3 cm with hour-range measurements. By employing a trend filter capable of detecting fiber faults in the n-OTDR fiber profile and interchanging between either OTDR techniques in an automatic fashion, we were able to harness the qualities of both in the minimum amount of measurement time. Our experimental results performed with multiple optical fiber links attest the structure’s capability of automatically detecting faults in an optical fiber link with ultra-high-resolution and minute-range measurements. Furthermore, tunability of the hybrid structure enabling the monitoring of wavelength-division multiplexed optical networks has been demonstrated.
