Abstract: A communication apparatus for a fiber-optic communication system for an aircraft that includes: an optical coupler; an input port optically coupled to the optical coupler via a first waveguide, the input port arranged to receive light; a modulator optically coupled to the optical coupler via a second waveguide, the modulator having a logic input and a fiber having a fiber Bragg grating (FBG) receiving light from the input port via the optical coupler, the modulator operable to vary a strain force applied to the fiber according to a logic signal received at the logic input to modulate a wavelength of a modulated light signal reflected by the FBG back to the optical coupler; and an output port optically coupled to the optical coupler via a third waveguide to receive the modulated light signal therefrom, the output port being operable to output the modulated light signal.

Abstract: A device for use in determining the rotational speed of a body. The device includes a sensor for detecting the strength of a magnetic field, and a body that is rotatable relative to the sensor about an axis. The body includes circumferentially spaced magnetic regions. The device is arranged so that, during rotation of the body relative to the sensor, the maximum strength detectable by the sensor of a first magnetic field of a first of the magnetic regions is different to the maximum strength detectable by the sensor of a second magnetic field of a second of the magnetic regions.
