DETAILED DESCRIPTION

[0039] Ribbon cables may be separated at a terminal portion for splicing or termination (e.g., into connectors, terminal blocks, or other equipment). This may involve splitting or separating a bonding material or dielectric between individual cables of the ribbon cable in order to separate the individual conductors or fibers. However, the bonding material or dielectric may not be perfectly or symmetrically split between two adjacent conductors or fibers, such that a majority of the material may randomly end up attached to one of the conductors or fibers or the other. This may result in unpredictable, unreliable, non-uniform and/or otherwise inferior optical performance or additional difficulty in cleaning fibers.

[0040] For example, FIGS. 1A and 1B are cross sections of a conventional implementation of a multi-conductor ribbon 100 (before separation) and 100 (after separation) lacking preferential separation. As shown, the ribbon 100 may comprise a plurality of individual conductors 101A, 101B that are bonded together via a bonding material. The conductors 101A, 101B may include signal transmission portions or optical fibers 102A, 102B, respectively. In some aspects according to the disclosure, instead of fibers, the conductors 101A, 101B may comprise copper wires, including for example bonded pairs of copper wire.

[0041] In many implementations, optical fibers 102A, 102B (referred to generally as fibers 102) may be encapsulated in a cover portion 104A, 104B, for example, a coating, which may comprise an insulating or dielectric material, such as polyvinyl chloride (PVC), polytetrafluoroethylene (PTFE or Teflon), polyvinylidene fluoride (PVDF), UV-curable materials including acrylate, epoxy, polyester, silicone, or styrene copolymer based materials, or any other such material. The conductors 101A, 101B may be bonded to one another via a bonding material 106, which may comprise silicone rubber, polyvinyl chloride (PVC), polytetrafluoroethylene (PTFE or Teflon), polyvinylidene fluoride (PVDF), fluorine resin, UV-curable materials including acrylate, epoxy, polyester, silicone, or styrene copolymer based materials, or any other such material, shown as a first portion 108A and a second portion 108B respectively attached to fiber 102A (via coating 104A), and fiber 102B (via coating 104B).

[0042] In the implementation shown, the bonding material 106 completely surrounds the coatings 104A, 104B, though in other implementations, less bonding material may be employed. For example, the bonding material may only cover a portion of the coatings 104A, 104B. The bonding material 106 includes a separation portion 110 (shown in dotted line) between the coatings 104A, 104B and/or the fibers 102A, 102B. In many such implementations lacking the preferential separation features discussed herein below, the bonding material 106 is laterally symmetrical around a vertical plane across the ribbon cable as shown. The bonding material also may be vertically symmetrical around a horizontal plane through the ribbon cable as shown (e.g., with identical dorsal and ventral portions). When separating the conductors 101A, 101B, the location of a separation region 112 may vary within the separation portion 110, and the bonding material 106 may unevenly tear or detach from one conductor (as shown in FIG. 1B). As a result of the uneven tearing, the conductors 101A, 101B may require additional cleaning, the fibers may be damaged, the conductors 101A, 101B may be prevented from being inserted into a furcation tube by excess bonding material that may adhere to the furcation tube, unpredictable, non-uniform, and/or otherwise different optical characteristics may occur, such as, for example, distributed or localized attenuation events, between the adjacent conductors, and/or removal of the bonding material or cleaning of the conductors or fibers may be more difficult.

[0043] Similarly, FIGS. 1C and 1D are cross sections of another implementation of a ribbon 100 (before separation) and 100, 100 (after separation) lacking the preferential separation features discussed herein below. While reducing the amount of bonding material in the separation portion 110 may reduce an amount of bonding residue remaining on one conductor after separation (e.g., 112B in the top version of FIG. 1D, or 112A in the bottom version of FIG. 1D), a corresponding larger amount of bonding material may remain as residue on the other conductor after separation (e.g., 112A in the top version of FIG. 1D, or 112B in the bottom version of FIG. 1D). The positions and amounts of the bonding residues are unpredictable or indeterminate, as shown in FIG. 1D, with the majority potentially ending up on either conductor 101A, 101B.

[0044] The present disclosure describes exemplary embodiments for providing multi-conductor optical fiber ribbon structures that may include a preferential and/or predictable separation region. By modifying a profile of a separation portion of bonding material between adjacent conductors of the ribbon or an amount of attachment between the bonding material and the adjacent conductors, the ribbon may be structurally configured such that a majority of the residual bonding material predictably, or in a predetermined or uniform manner, remains on a selected one of the adjacent conductors. This profile may be dynamically varied along a length of the ribbon to provide similar or conforming optical characteristics between adjacent conductors and/or may reduce installation (e.g., splicing and/or termination) or cleaning times by concentrating bonding residue on preferential and/or predicted conductors and/or prevent damage to the optical fibers.

[0045] FIGS. 2A and 2B are cross sections of an exemplary embodiment of a multi-conductor optical fiber ribbon 200 (before separation) and 200 (after separation) that is structurally configured to provide a preferential separation region between adjacent individual conductors 201A, 201B. In the illustrated embodiment, the conductors 201A, 201B may respectively include fibers 202A and 202B with a coating 204A, 204B. The conductors 201A, 201B may partially or wholly surrounded by a bonding material 206 with a first portion 208A and second portion 208B. The bonding material 206 may include a separation portion 220 (alternatively referred to as a bonding area, bonding region, coupling region, coupling structure, or by similar terms). As shown, the separation portion 220 may lack lateral symmetry (although may have vertical symmetry, as in the illustrated embodiment). The separation portion 220 may be structurally configured to provide a preferential separation region 222 between adjacent individual conductors 201A, 201B. For example, because the separation portion 220 has a reduced amount of bonding material 206 adjacent or proximate to conductors 201B (i.e., adjacent to the coating 204B and/or the fiber 202B), the bonding material 206 will predictably detach or separate at the preferential separation region 222 of the separation portion 220 in a predetermined or uniform manner, as shown in FIG. 2B.

[0046] While such embodiments of a preferential separation region 222 may still result in different amounts of bonding material on each conductor 201A, 201B after separation, the result is predictable, or in a predetermined, uniformed, controlled, or conforming manner, and may be selected to avoid distributed or localized impairments to optical characteristics or other performance characteristics of the ribbon. For example, the preferential separation region 222 may be structurally configured to predictably, or in a predetermined a manner, leave bonding residue on dark fibers, etc.

[0047] Furthermore, the bonding regions need not be continuous longitudinally along the length of the ribbon. FIG. 2C is a top right perspective view of an implementation of a ribbon 200 having preferential separation with intermittent or non-continuous separation portions 220 of bonding material 206. Such ribbons 200 may have greater flexibility relative to ribbons with continuous bonding material. Additionally, in some implementations, alternating separation portions along the length of the ribbon may have opposing orientations, such that each adjacent conductor alternately retains the separation portion after separation, resulting in similar average performance and optical attenuation characteristics between the individual conductors 201A, 201B over the separated or unseparated length (which may include a large number of such separation portions, such as implementations where the separation portions are separated by a small amount, e.g., on the order of centimeters, and the separated length of the conductors is significantly longer, e.g., 0.5 meters, 1 meter, or longer). For example, the attenuation effects over hundreds of meters may be better distributed between fibers, or preferentially applied to fibers to compensate for other effects due to position in the ribbon, such as, for example, higher attenuation of edge fibers due to bundling/bunching.

[0048] Although shown with only two conductors in FIGS. 2A-2C, bonding material with separation regions may be used throughout larger ribbons (i.e., ribbons having more than two conductors). For example, FIGS. 3A and 3B are cross sections of implementations of ribbons 300, 300 having separation regions 220A, 220B between individual conductors 301A, 301B, 301C. In both implementations of FIGS. 3A and 3B, each separation region 220A, 220B lacks individual lateral symmetry (though the separation regions 220A, 220B may be laterally symmetric to each other, as shown with region 220A being symmetric with region 220B across a vertical plane through the center conductor). As discussed above, when intermittent or non-continuous separation regions are utilized, the separation regions 220A, 220B need not be located at the same longitudinal position on the ribbon 300, 300. For example, preferential separation region 220A may be located at a first longitudinal position on the ribbon, and preferential separation region 220B may be located at a second longitudinal position spaced away from the first longitudinal position further along a length of the ribbon. This arrangement may allow for greater flexibility in the ribbon 300, 300.

[0049] While the embodiment of FIG. 3A shows separation regions 220A, 220B having a first dimension in the lateral direction, smaller separation regions 220A, 220B may be used in other embodiments, as shown in FIG. 3B.

[0050] In the embodiments of FIGS. 2A-2C and 3A-3B, the bonding material 206 completely surrounds the individual conductors (i.e., the coated fibers). In other embodiments, the bonding material 206 may only partially surround the individual conductors (i.e., the coated fibers). In some embodiments, the bonding material 206 may only be present in the separation region between adjacent individual conductors.

[0051] In some embodiments, as shown in FIG. 3C, a bonding material 306 may surround only some of the individual conductors. FIG. 3C is a cross section of such an embodiment of a ribbon 300C having the bonding material 306 surrounding only a center conductor 301A between adjacent conductors 301B, 301C of a group of three conductors. The bonding material 306 may be attached to the coatings 304B, 304C of the adjacent conductors 301B, 301C at separation regions 320A, 320B as shown. The adhesion strength of the bond between the bonding material 306 and the coatings 304B, 304C may be less than the cohesive strength of the bonding material 306, such that the adjacent conductors 301B, 301C may be separated from the center conductors 301A without tearing the bonding material 306.

[0052] In a similar embodiment illustrated in FIG. 3D, a ribbon 300D may include a plurality of individual conductors 301, where alternating conductors 301A-301F of the plurality of individual conductors 301 are each surrounded with bonding material 306A-306F at longitudinally separated positions. By alternating high and low adhesion bonds along the length between two adjacent individual conductors, attenuation effects may be distributed between them, reducing or eliminating unpredictability and optical characteristic differences. The bonding of the ribbon 300D may be referred to as a web, as the ribbon may be gently stretched laterally with gaps opening between adjacent individual conductors between the longitudinally separated positions of the bonding material 306A-306F on said adjacent individual conductors. This may improve flexibility of the ribbon relative to fully bonded ribbons, and also speed installation (e.g., splicing and/or termination) by reducing the amount of bonding material present, which may need to be cleaned or removed, in some installation methods. In some embodiments, a ribbon may include longitudinal lengths with no bonds, thereby facilitating ribbon flatness or planarity for ease of fusion splicing or termination of multiple conductors simultaneously.

[0053] While the embodiments discussed above may comprise a separation portion of bonding material that lacked lateral symmetry but possessed vertical symmetry, other embodiments may lack both lateral and vertical symmetry of the separation portion. For instance, FIGS. 4A and 4B illustrate a cross sectional and top left perspective view of another embodiment of a ribbon 400, 400 having individual conductors 401A, 401B at least partially covered by a bonding material 406 that includes a first portion 408A and second portion 408B, where the bonding material 406 includes a separation portion 420 configured to provide a preferential separation region 422. As shown, separation portion 420 may be structurally configured to lack any lateral or vertical symmetry, which may allow for a smaller separation portion 420 of bonding material 406 in some implementations. Such implementations also may reduce attenuation effects on a first conductors 401A, which includes a fiber 402A and a coating 404A, that retains the separation portion after separation, as a majority of the material may be moved farther from a center of a second conductor 401B, which includes a fiber 402B and a coating 404B. As shown in the embodiment of FIG. 4B, the separation portions 420, 420 may be structurally configured differently between each adjacent individual conductor 401. This also may vary along the longitudinal length of the ribbon 400, such that different individual conductors 401 are easily separated without bonding residue or with minimal residue at different positions.

[0054] Accordingly, the embodiments of the ribbons discussed herein provide preferential and/or predictable separation regions between adjacent individual conductors comprising fibers of the ribbons, which may increase installation (e.g., splicing and/or termination) efficiency and reduce optical characteristic differences by distributing effects between different conductors or moving them to dark fibers.

[0055] In a first aspect, the present disclosure may be directed to multi-conductor optical fiber ribbon cable structures. Such ribbon cable structures may include a plurality of parallel optical fibers, each fiber being surrounded by a coating having an outer surface. These ribbon cable structures also may include a coupling structure fixed to a first outer surface of a coating of a first optical fiber and a second outer surface of a coating of a second optical fiber of the plurality of optical fibers. A first bonding area between the first outer surface and the coupling structure may be larger than a second bonding area between the second outer surface and the coupling structure.

[0056] In some implementations, the coupling structure may be structurally configured to lack lateral symmetry between the first optical fiber and the second optical fiber. In a further implementation, the coupling structure may be structurally configured to lack vertical symmetry between the first optical fiber and the second optical fiber.

[0057] In another aspect, the present disclosure may be directed to other types of multi-conductor optical fiber ribbon cable structures. Such other types of ribbon cable structures may include a first coated optical fiber, a second coated optical fiber that may be structurally configured to extend parallel to the first coated optical fiber, and a coupling structure that may be structurally configured to partially or wholly surround the first coated optical fiber and be separately attached to the second coated optical fiber at a bonding surface at a first longitudinal position along the ribbon, the coupling structure may be structurally configured to not surround the second coated optical fiber at the first longitudinal position along the ribbon cable.

[0058] In some implementations, such ribbon cable structures may include a third coated optical fiber that may be structurally configured to extend parallel to the second coated optical fiber and the first coated optical fiber, and a second coupling structure that may be configured to partially or wholly surround the third coated optical fiber and be separably attached to the second coated optical fiber at a second bonding surface at a second longitudinal position along the ribbon, and the second coupling structure may be configured to not partially or wholly surround the second coated optical fiber at the second longitudinal position along the ribbon.

[0059] Persons skilled in the art would understand that the ribbon structures disclosed herein may be used to create lighter separation forces between adjacent fibers in the absence of solenoid/resin applicators that have short deposit times. The offset and subsequent smaller contact area disclosed herein may create lighter separation forces, which overcomes the need for equipment with shorter opening and closing times and, thus, reduces the cost of the system and replacement parts.

[0060] The above description in conjunction with the above-reference drawings sets forth a variety of embodiments for exemplary purposes, which are in no way intended to limit the scope of the described methods or systems. Those having skill in the relevant art can modify the described methods and systems in various ways without departing from the broadest scope of the described methods and systems. Thus, the scope of the methods and systems described herein should not be limited by any of the exemplary embodiments and should be defined in accordance with the accompanying claims and their equivalents.
