摘要： A translucent dust cap for a fiber optic adapter allows the viewing of visible light emanating from a fiber optic connector coupled to the adapter, without removing the dust cap. A translucent dust cap for a fiber optic adapter that serves to diffuse a visible light source of sufficient power, such as that from a VFL, and lights up to aid in connector identification. A translucent dust cap for a fiber optic adapter that serves to attenuate infrared optical transmission power to prevent eye damage.

摘要： Methods are provided for validating the continuity of one or more optical fibers upon which a fiber optic connector is mounted. Typically, the fiber optic connector is mounted upon an optical field fiber by actuating a cam mechanism to secure the optical field fiber in position relative to an optical fiber stub. If subsequent testing indicates that the continuity of the optical field fiber and the optical fiber stub is unacceptable, the cam mechanism can be deactuated, the optical field fiber can be repositioned and the cam mechanism can be reactuated without having to remove and replace the fiber optic connector. In order to determine if continuity has been established between the optical field fibers and respective optical fiber stubs, a method is also provided that introduces light into at least one of each pair of optical field fibers and optical fiber stubs and that only secures the position of each optical field fiber relative to the respective optical fiber stub once the glow associated with each pair of optical field fibers and optical fiber stubs dissipates, which dissipation indicates the establishment of continuity. An improved multifiber connector and installation tool are also provided to facilitate the establishment and validation of the continuity of optical field fibers and optical fiber stubs in order to reduce the time and cost required to connectorize optical field fibers in the field.

摘要： A tool is provided for removing a ferrule from a receptacle that includes a handle portion having a distal end and a proximal end and a ferrule engagement portion disposed at the distal end of the handle portion. The tool also includes a latch disengagement portion disposed at the distal end of the handle portion. The tool handle may be angled for easier access if the receptacle is attached to a printed circuit board. Additionally, the tool may include an optical fiber opening to prevent the optical fibers from being bent or damaged during the ferrule removal.

摘要： Devices and methods are described that permit simple correction of a fiber optic polarity reversal problem. An adapter is described having receptacles to receive a connector on a first end, or user end, and on a second end, or contractor end. Both the receptacles provide keying arrangements so that the connectors can be received only when correctly oriented with respect to the adapter. The keying arrangement on the contractor end, however, is reversable so that the connector may be inserted in one of two predetermined orientations, at the behest of the contractor or installer. Adapters are also described that receive connectors only in a physically reversed orientation to counteract a reverse polarity condition. In addition, a jumper is described that can be interposed between a connector and adapter to correct a reverse polarity condition.

摘要： The present invention provides an adapter for sealingly receiving ferrules of standard optical fiber connectors such that the end faces of the ferrules are protected from moisture when inserted into the adapter. The adapter has a sealing sleeve that defines a sealing surface at each end to circumferentially seal about a ferrule. An alignment sleeve that is sized for operatively aligning the end faces of the ferrules is disposed coaxially inside the sealing sleeve. A retainer retains the sealing sleeve and allows for mounting of connectors thereto.
