    Abstract: A fiber optic splice closure includes at least one first splice organizer tray having one end pivotally connected to a base and extending in a medial portion of a housing; a mounting member pivotally connected to the base adjacent the at least one first splice organizer tray; and at least one second splice organizer tray pivotally connected to the mounting member on a side thereof opposite the at least one first splice organizer tray. The splice closure also preferably includes a slack storage tray connected to the base and positioned in the housing adjacent a side of the at least one first splice tray that is opposite the mounting member. The splice closure thus provides a compact, yet flexible, closure facilitating drops to a fiber optic ring network. The at least one first splice organizer tray is preferably pivotal about a first axis, and the at least one second splice organizer tray is also preferably pivotal about a second axis generally parallel to the first axis. In addition, the housing may have a generally cylindrical shape defining a longitudinal axis generally transverse to the first and second axes. The mounting member is preferably pivotal about a third axis parallel to the first and second axes. At least one optical fiber may be preinstalled between first and second splice trays.

    Abstract: A fiber optic splice closure includes a series of stacked splice trays pivotally secured within a housing, and oval shaped generally flexible transport tubes carrying the exposed optical fibers to the splice trays within the closure. The transport tubes have a differential flexibility to permit bending i a direction generally normal to the major dimension of the tube while preventing bending in a direction generally normal to the minor dimension of the tube. Accordingly, optical fiber ribbons carried by the transport tubes are protected from bending in a direction normal to their minor dimension. The splice trays are pivotally secured at one end to a bracket secured to an end cap of the housing. A hinge for each splice tray includes detents to hold an individual tray in a raised position to thereby facilitate access to an underlying tray. In addition, splice holders are provided on each splice tray and include a series of generally flexible walls extending outwardly from a base. The flexible walls further include hollow cavities to more readily accommodate splices of different sizes. A generally rigid shell with a predetermined pattern of openings therein is positioned to overlie the base carrying the flexible walls.

    Abstract: A method of routing optical fiber ribbons within a fiber optic splice closure is disclosed. A plurality of optical fiber ribbons are exposed for a splicing operation. The optical fiber ribbons are stacked in a sequential arrangement within a fiber optic feed tube positioned within a fiber optic splice closure. A ribbon organizer is installed over the optical fiber ribbons at an opening of the fiber optic feed tube. The interior dimensions of the ribbon organizer substantially match the size and shape of the plurality of optical fiber ribbons. The original stacked, sequential arrangement of the optical fiber ribbons are re-established by sliding the ribbon organizer down along the length of the optical fiber ribbons, thereby orienting the optical fiber ribbons into their original positions as they are within the fiber optic feed tube.

    Abstract: A fiber optic splice organizer for storing optical fiber splices and the slack associated therewith to permit ready separation of the optical fibers, such as to remake a splice. The splice organizer includes a generally rectangular base, splice securing slots on the base, and optical fiber guides for guiding slack portions of first and second optical fiber groups from a first end of the base, along respective portions of the base adjacent the first and second sides thereof, into a plurality of overlying slack loops adjacent the second end of the base, and back to the splice securing means from respective first and second sides of the base. The slack optical fibers, including the overlying respective slack loop, of the first and second optical fiber groups, form a figure-eight pattern on the base and are thus readily separable from each other. An ability to interconnect individual optical fibers broken out from optical fiber ribbons is also provided by crossing first and second groups of optical fiber ribbons and breaking out individual optical fibers at the crossover point. Arcuately shaped walls on the base are provided to maintain the individual fibers in a predetermined bend radius. A series of tabs along sidewalls of the base separate the individual fibers from the optical fiber ribbons downstream from the crossover point.
