Dual-Stage Modulation Correlation OTDR for High-Resolution Monitoring in Passive Optical Networks

Utilizing SOA and dual-stage modulation, we achieve correlation OTDR with 14.8dB dynamic range and <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$&lt;2 \text{cm}$</tex> spatial resolution in typical PON scenarios. The approach achieves higher peak-noise-level compared to correlation schemes using continuous signal.

Abstract

Utilizing SOA and dual-stage modulation, we achieve correlation OTDR with 14.8dB dynamic range and <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$&lt;2 \text{cm}$</tex> spatial resolution in typical PON scenarios. The approach achieves higher peak-noise-level compared to correlation schemes using continuous signal.
