A newly designed room-temperature, sine-wave gated, InGaAs/InP SPAD based photon
counting system with dead-time mitigation is described in this work. In this system, an …

Single photon detector (SPD) has a maximum count rate due to its dead time, which results
in that the dynamic range of photon counting optical time-domain reflectometry (PC-OTDR) …

A 15 dB dynamic range and 4.6 cm spatial resolution tunable photon-counting optical time-
domain reflectometer (PC-OTDR) is presented along with a Field Programmable Gate Array …

A photon-counting optical time-domain reflectometry (PC-OTDR) based optical fiber
temperature sensor system is proposed and demonstrated experimentally in this work. In the …

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 (ν-OTDR), is presented …

This paper represents a review of several published papers, white papers and posted
articles with a view to explain background of fault detection techniques for optical fibers …

Identifying the unknown underlying trend of a given noisy signal is extremely useful for a
wide range of applications. The number of potential trends might be exponential, thus their …

We present a setup capable of overcoming the saturation output power of semiconductor
optical amplifiers operating in the pulsed regime. The concept is to couple different time …

This paper proposes a scheme of photon counting infinite backscatter optical time domain
reflectometry (PC-IR-OTDR). In order to verify the feasibility of the scheme and analyze the …
