Abstract: An apparatus for optical signal detection may include a housing in which a channel may be defined to receive an optical fiber in a bent configuration. The channel may have a predetermined radius of curvature to cause optical energy to escape from the fiber when an optical signal is being conveyed in the fiber and be detected at a photodetector arranged at the predetermined radius of curvature.

Abstract: An apparatus for monitoring optical signal transmission in a plurality of optical fibers may include a fixture for introducing a bend into the plurality of fibers arranged at respective predetermined locations on the fixture, to cause a portion of light propagating in any of the fibers to scatter out therefrom. The apparatus may include a lens unit positioned to focus the scattered light onto predetermined photo-detectors of an array, in accordance with the fiber from which the scattered light emanates, and generate image data indicating a characteristic of the scattered light detected at respective ones of the photo-detectors identified by location in the array corresponding to the respective ones of the photo-detectors.
