High-Sensitivity Coherent Optical Time Domain Reflectometry Employing Frequency-Division Multiplexing

This paper proposes a novel parallel detection scheme for enhancing the sensitivity of coherent optical time domain reflectometry (C-OTDR). The proposed scheme is based on frequency-division multiplexing using a phase modulator and software processing. The performance advantages of the proposed meth...
