EXFO’s FIP-200 Connector Checker ensures trouble-free broadband activation in one click, while the AXS-120 mini-Optical Time Domain Reflectometer (OTDR) improves field testing of last mile FTTH access ...
Abstract: Phase-sensitive optical time domain reflectometry (φ-OTDR) can be used to recover external vibration information through phase demodulation. However, with the restriction of the unwrapping ...
Abstract: The phase signals, combined with time-domain signal processing methods, are often used for recognition with the phase-sensitive optical time-domain reflectometer (Φ-OTDR). Considering the ...
