Does a Brillouin temperature-strain interrogator on ordinary telecom fiber actually resolve a hot-spot and a settlement at 80 kilometers without a single glued gauge

Can an ordinary telecom fiber really become a continuous microphone that hears leaks and intruders along 50 kilometers without a single powered sensor

Can a single armored weak-grating cable simultaneously resolve temperature and strain without the cross-talk that kills discrete FBG dual-parameter readings

Does an armored weak-grating FBG array cable actually solve the dense strain-mapping problem that discrete point sensors and electrical gauges leave behind on long bridges

Can a rail mounted dual channel voltage module really capture main to backup power switching transients while displaying real time status through dedicated indicator lights
