APPARATUS FOR STORING FIBER OPTIC FIBERS AND METHODS FOR USING IT
Related Requests This application claims the priority of United States Provisional Application No. 60 / 29,575 (case of attorney-in-fact No. E-TO-00085 / 5487-240PR), filed on October 24, 2005, whose descriptive memory remains incorporated here in its entirety, by means of this reference. BACKGROUND OF THE INVENTION The present invention relates to fiber optic products and, more particularly, to products for storing optical fiber and methods for using them. More and more networks are being installed. fiber optic to support high-speed voice and data communications. Increasingly fiber optic coupling is expanding from the central office of the communication service provider companies, such as the Regional Bell Operating Companies (RBOC) to the subscriber sites, such as homes or businesses; where conventional copper wiring was conventionally used. In various places, in a fiber optic network, fibers or the like should be tied or spliced in an organized manner. Trays for splicing fiber, or the like, can be used to provide such splices in an organized manner. However, several applications may have limited space available to receive such splice trays, which may restrict the possibility of providing an adequate splice tray. Additionally, conventional splice trays are flat and non-movable; therefore, they generally require the splicer technician to manually load and extract the fibers from the tray. Storing and removing all fibers at the same time can be an important aspect of keeping a splice tray loaded randomly. For example, fiber 4 can be spliced on day one, and fiber 6 can be spliced on day two, and the remainder can be spliced for a period of time in a random order, for a randomly loaded splice tray. If all the fibers are not completely undone each time a splice is made, an unmanageable rat nest, of entangled fibers, may result from repeated access to add the fiber splices.

The apparatus for storing optical fiber splices according to some embodiments of the present invention will now be described with reference to figures 1 to 9. With reference primarily to the embodiments illustrated in FIGS. 1 and 2, an apparatus 100 for storing splices of Optical fiber is illustrated having a first plurality of optical fibers 105 and a second plurality of optical fibers 1 10. More particularly, the apparatus for storing optical fiber splices illustrated in Figures 1 and 2 is shown as a splice tray that is hinged in three folds. The apparatus 100 may be used, for example, in confined spaces, cabinets, pedestals, boxes, shelves and the like, where splices and / or shunts are provided between respective fiber optic cables, and for storage of associated loose fiber which may be necessary for connections with the formation of splices or the like using, for example, external splicing equipment. The illustrated splice tray 100 includes a central segment 12, a first loose fiber storage segment 120 and a second loose fiber storage segment 130. The first and second loose fiber storage segments 120, 130 are pivotally connected, respectively, to a first end 1 18 and a second opposite end 122 of the central segment 1 12. The central segment 1 12 defines a splice chamber 1 14, configured to receive a plurality of fiber optic splices 1 16. Each of the first and second loose fiber storage segments 1 20, 1 30 has an open position extending from the first and second ends 1 1 8, 122, respectively, away from the central segment 1 12, such as it is illustrated in Figures 1 and 2, and a closed position that extends over the center segment 1 12, as illustrated in Figure 6. As best seen in Figure 2, a first plurality of guide members is provided. loose fiber 1 28 in the first loose fiber storage segment 1 20, which are configured to receive and retain a loop 1 05a of the optical fibers 1 05. A plurality of loose fiber guide members 1 32 in the second segment 1 30 of loose fiber storage, is configured to receive and retain a bundle 1 1 0a of the optical fibers 1 1 0. As seen also in Figures 1 and 2, a member 1 38 splice receiver in the central segment 1 1 2 also provides a guide member fiber for the respective selected fibers of the optical fibers 1 05 and 1 1 0, which are joined together In the illustrated embodiments of Figures 1 and 2, the splice receiving member 38 serves both as a guiding member for the spliced fibers of the respective plurality of fibers 1 05, 1 1 0, and additionally provides a positioning slot arrangement for receiving a splice formed between the respective fibers with a protective sheath thereon. Also illustrated are inlet / outlet fiber guide members in the central segment 112. More particularly, a fiber inlet 136 to the splice chamber 114 allows access to the chamber 114 and defines a fiber guide member for the first plurality of fibers 105; and a fiber outlet 134 to the junction chamber 114 gives access to the chamber 114 and defines a guide member for the second plurality of optical fibers 110 in the central segment 112. The fiber entry 136 in the central segment 112 and a member 128a, 128b of the first plurality of loose fiber guide members 128, define a first fiber path 207 extending from the central segment 112 to the first loose fiber storage segment 120. The fiber outlet 134 and a member 132a, 132b of the second plurality of the loose fiber guide members 132 define a second fiber path 205 extending from the central segment 112 to the second loose fiber storage segment 130. As further shown in Figure 2, the splice receiving member 138 and a second member 128a ', 128b' of the first plurality of the loose fiber guide members 128 define a third fiber path 209, extending from the central segment 112 to the first loose fiber storage segment 120. The splice receiving member 138 and a second member 132a ', 132b' of the second plurality of loose fiber guide members 132 define a fourth fiber path 211, which extends from the central segment 112 to the second storage segment 130 of loose fiber. An intersection of the first fiber path 207 and the third fiber path 209 define a first fiber crossing location 220, close to an intermediate or middle portion of the first end 1 18 of the center segment 1 12. The first crossing location 220 of fiber is positioned so as to limit the flexure of the optical fibers that extend along the first fiber path 207 and the third fiber path 209, when the first loose fiber storage segment is moved from its open position (figure 1) to its closed position (figure 4, 5 and 6). In other words, the respective optical fibers are predominantly subjected to twisting during rotation, while maintaining a minimum recommended bending radius, to reduce the risk of damage to the fibers during closure of the first loose fiber storage segment 120 . The second fiber path 205 and the fourth fiber path 21 1 define a second fiber crossing location 222, close to an intermediate or middle portion of the second end 1 16 of the center segment 1 12, to similarly limit the bending of the fiber. the optical fibers of the plurality of optical fibers 1 1 0 extending along the second fiber paths 205 and fourth 21 1, when the second loose fiber storage segment 130 moves from its open position (FIG. 2) to its closed position (figure 6). As shown in Figures 1 and 2, in the illustrated embodiments, the respective loose fiber guide members 128, 132 may be opposite pairs of guide members. As seen in Figures 1 and 2, the respective pairs can be opposite ears and / or fasteners, provided in pairs 1 28a, 1 28b, 1 28a ', 128b', 132a, 132b, 132a ', 1 32b'. Also as shown in the embodiments of Figures 1 and 2, the pivotal connection between the respective loose fiber storage segments 1 20, 1 and the central segment 1 12 may be provided by a respective first hinge 140 and a second hinge. respective 1 50. In some embodiments, the first and second hinges 140, 1 50 may be live hinges and the central segment 1 1 2, the first loose fiber storage segment 120 and the second loose fiber storage segment 1 30 may be of polypropylene (PP). In other embodiments a mechanical hinge can be used, as shown in Figures 1 and 2, and the central segment 1 12, the first loose fiber storage segment 120 and the second loose fiber storage segment 1 30 can be polycarbonate and / or other suitable engineering thermoplastic. As seen in Figure 2, in the illustrated embodiments, the first plurality of optical fibers 105 extends along the first fiber path 207 and the third fiber path 209, and they are gathered in a bundle 105 in the first loose fiber storage segment 1 20, so that the first plurality of optical fibers 1 05 intersects itself close to the first fiber crossing location 220. The second plurality of optical fibers 1 10 extends along the second fiber path 205 and the fourth fiber path 21 1, and are formed in a bundle 1 10 a in the second loose fiber storage segment 130, so that the second plurality of optical fibers 1 10 intersect on itself close to the location 222 of the second fiber crossing. As seen also in Figure 2, fibers of the first plurality of optical fibers 105 are spliced to corresponding fibers of the second plurality of optical fibers 1 10, to define a plurality of optical fiber splices 1 16. For example, the first plurality of optical fibers 105 may be fibers that extend from a subscriber location, and may be coupled by splices to a second plurality of optical fibers 1 10 extending to a connection panel associated with an office central or similar, for use in selectively providing a service to some subscribers associated with respective optical fibers included in the first plurality of optical fibers 105. More particularly, the first plurality of optical fibers 105 can be detachably retained with a loop 105a therein, in the first loose fiber storage segment 120, by means of a first plurality of loose fiber guide members 128. The second plurality of optical fibers 1 10 can be releasably retained with a loop 1 10a therein, in the second loose fiber storage segment 130, by means of the second plurality of loose fiber guide members 1 32. In that way, when an operator accesses the individual fibers for the purpose of forming a joint 16 or the like, he can separately extract the loops 105 a, 1 a from the respective plurality of fibers 105, 1 10, to access the fibers individual, and then return the loops using the fastener members after the formation of the splice. Said way of proceeding can reduce the entanglement and the like of the respective optical fibers, since the splices can be formed in different combinations and at different times, which requires repeated access to the respective optical fibers. While the illustrated embodiments of an apparatus for storing optical fiber splices, or splice tray 100, have been described generally further back, primarily with reference to the open positions of Figures 1 and 2, the splice tray 100 is further illustrated in different conditions in Figures 3 to 6. More particularly, Figure 3 illustrates the first loose fiber storage segment 120 in transition from its open position to a closed position, extending over the central segment 1 12. The figure 4 illustrates the first loose fiber segment 120 in its closed position, which extends over the central segment 1 12, while the second loose fiber storage segment 130 is still in the open position.
