摘要： An optical fiber winding tool for winding a strip of optical fiber. The optical fiber winding tool having a guiding body defining a guiding recess. A fiber inlet aperture extends into the guiding recess for allowing the slideable insertion of the strip of optical fiber thereinto. The recess peripheral wall is configured and sized such that as the strip of optical fiber is inserted through the fiber inlet aperture, a recess peripheral surface abuttingly guides the optical fiber strip into a generally parabolic configuration that sweeps against the recess peripheral surface while the optical fiber winds into a coil. The optical fiber winding tool is mountable over a flat surface with the peripheral edge of the guiding recess abuttingly contacting the supporting surface. A driving assembly is optionally provided for driving the strip of fiber into the guiding recess.

摘要： A notch filter system, where multiple filter passes of a light signal may be effected for removing a target spectral component from the light signal, is provided. Advantageously, the notch filter system may be tunable. A cascade notch filter system is provided which includes multiple notch filters arranged in a cascade, each of the filters having spectral filtering characteristics and being disposed in the path of the light signal at an appropriate filter angle so that the target spectral component is filtered out of the light signal as the light signal passes therethrough. A multipass notch filter system is provided which includes a notch filter having spectral filtering characteristics, and an optical assembly for directing the light signal for multiple filter passes through the filter at an appropriate angle, so that the target spectral component is filtered out of the light signal as the light signal passes through the filter.
