Abstract: An optical demultiplexing device includes an optics body, a mirror, optical filters, and opto-electronic detectors. The optics body has a fiber port configured to receive an end of an optical fiber, a reflective surface aligned with the fiber port, a substantially planar filter mounting surface, and a substantially planar mirror mounting surface. The filter mounting surface and the mirror mounting surface are parallel to one another and formed on the same side of the optics body as each other. The mirror is mounted on the mirror mounting surface, and the filters are mounted on the filter mounting surface. Each filter is transparent to a different wavelength and is interposed in an optical path between one of the opto-electronic detectors and the reflector.

Abstract: A transmitter optical sub-assembly receptacle includes a thicker split sleeve positioned within a cylindrical shell structure and partly within a base structure such that a fiber ferrule, which is positioned within the base structure, is partly within the thicker split sleeve. The split sleeve has a thickness larger than 0.187 millimeter.

Abstract: A low-cost molded sleeve for a fiber optic cable connector receptacle is disclosed. The inner surface of the sleeve, into which a fiber optic connector can be inserted, is defined by three surfaces. A first planar surface and a second planar surface at right angles to each other form a V-shaped groove for holding the a fiber optic connector. Clamping action is applied to a third surface to hold the a fiber optic connector in place in the V-shaped groove such that optical coupling is achieved.

Abstract: According to an aspect of the invention, an optical fiber receptacle adaptor is provided. The optical fiber receptacle adaptor has a receptacle end and a port end. The receptacle end is secureable to an optical fiber receptacle and is adapted to receive a free end of the optical fiber receptacle. The port end is adapted to receive an optical ferrule, and for urging the optical ferrule into communication with the free end of the optical fiber receptacle.
