ABSTRACT:
An optical fiber system for gathering and transmitting data about a plurality of operating parameters in an aircraft gas turbine engine is disclosed. Broadband light from a light source is conducted through an optical fiber to a wavelength splitter/combiner which separates the received light signal into a number of discrete output wavelengths. Each wavelength is transmitted to a corresponding optical switch which is responsive to a monitored engine or environmental parameter to reflect all, none or a portion of the received light wavelength. The wavelength splitter/combiner multiplexes the reflected wavelengths into a single signal containing information pertaining to all monitored parameters.
