Abstract: Conventional chirped-pulse (CP) phase-sensitive optical time-domain reflectometry (CP φ-OTDR) allows the interrogation of tens of kilometers of optical fiber with high accuracies of millikelvin or nanostrain. With respect to standard coherent-detection φ-OTDR, it shows increased… read more here.
