1. An optical fiber sensing system comprising:
an optical fiber network that detects first sensing information related to a first monitoring target and second sensing information related to a second monitoring target;
a memory storing instructions; and
at least one processor, by executing the instructions, configured to implement:
a reception unit configured to receive an optical signal from the optical fiber network;
a specification unit configured to specify the first monitoring target based on the first sensing information superimposed on the optical signal and specify the second monitoring target based on the second sensing information superimposed on the optical signal; and
a provision unit configured to provide information related to the first monitoring target and information related to the second monitoring target specified by the specification unit for a service providing destination,
wherein the provision unit is further configured to:
provide the information related to the first monitoring target specified by the specification unit for a first service providing destination, and
provide the information related to the second monitoring target specified by the specification unit for a second service providing destination.
