A method of providing a hybrid distributed fiber optic sensing system (DFOS) that extends an existing fiber optic telecommunications network thereby providing that existing fiber optic telecommunications network with DFOS capabilities. The method provides a length of fiber optic cable, wherein said fiber optic cable conveys communications traffic; provides a DFOS interrogator system in optical communication with the communications fiber optic cable; extends the length of communications fiber optic cable with first and second lengths of fiber optic sensory cable, and operates the DFOS interrogator system such that first sensory data is generated in the first length of fiber optic sensory cable and second sensory data is generated in the second length of fiber optic sensory cable and conveyed to the DFOS interrogator system via the communications fiber optic cable, wherein the first type of sensory data and the second type of sensory data is a type selected from the group consisting of acoustic data, temperature data, and vibration data and the first type of sensory data is not the same type as the second type of sensory data.
A method of providing a hybrid, distributed fiber optic sensing (DFOS) system with improved connection to existing deployed fiber infrastructure, said method comprising:
