Vibration Detection and Localization in Buried Fiber Cable after 80km of SSMF using Digital Coherent Sensing System with Co-Propagating 600Gb/s WDM Channels

Not Accessible

Your library or personal account may give you access

Abstract

We report detection-localization-identification of true mechanical events on a buried fiber cable up to 82km SSMF using a digital sensing system copropagating with adjacent 600Gb/s WDM channels. Non-intrusive coexistence with WDM channels is demonstrated.
