Abstract
A passive wavelength-division multiplexing fiber-optic temperature sensor, as well as a distributed fiber-optic temperature sensing system, incorporates at least one wavelength-division-multiplexing optical coupler, so that any given sensor interfaces optically by at least one designated optical wavelength, thus providing means for any given fiber-optic temperature sensor to be distinguished from other fiber-optic temperature sensors of similar design operating on the same optical fiber system.
