Description
Background
[0001] 1. Field of the Invention
[0002] This invention relates to hybrid electrical and optical cable assemblies. More particularly, the invention relates to a electrical and optical hybrid cable with an in-line transition housing between the hybrid cable and individual termination jumpers for the several conductors of the cable.
[0003] 2. Description of Related Art
[0004] The wireless communications industry is changing from traditional signal delivery from ground based transceivers delivering/receiving the RF signal to/from the antenna atop the radio tower via bulky/heavy/high material cost metal RF coaxial cable to optical signal delivery to a tower top mounted transceiver known as a remote radio unit (RRU) or remote radio head (RRH) with implementation of FTTA (Fiber To The Antenna) cabling.
[0005] FTTA cabling may be simplified where power and/or control signal conductors are provided with optical signal conductors in a single hybrid cable.
[0006] Optical conductors may be fragile, requiring great care to properly terminate.
[0007] Prior hybrid cable RRU/RRH terminations have employed an over-voltage protection and/or distribution box for terminating each of the electrical and optical conductors as individual jumpers. These additional enclosures require field termination of the several conductors atop the radio tower, increasing installation time and labor requirements. Further, each break in the conductors provides another opportunity for signal degradation and/or environmental fouling.
[0008] Factory terminated hybrid cable assemblies are known. However, these assemblies may apply splices to the conductors, require a relatively large in-line break-out/splice enclosure and/or utilize environmental seals which fail to positively interlock the jumpers therewith, which may increase the potential for cable and/or individual conductor damage to occur.
[0009] Therefore, an object of the invention is to provide an optical fiber/electrical cable assembly with sealed breakout kit and/or cable assembly and method of use that overcomes deficiencies in the prior art.

Detailed Description
[0049] The inventor has recognized that individual conductors of a hybrid electrical and optical conductor cable may be broken out into individual jumpers, without requiring termination and/or or splicing of the individual and/or groups of related conductors, by removing outer protective layers of the hybrid cable and providing protective sheaths for each of the conductors and/or conductor groups, the protective sheaths positively interlocked with the hybrid cable via a transition housing.
[0050] A typical hybrid cable, for example an FTTA cable, includes multiple metal (such as copper) conductors and single or multiple optical fibers in a subunit. A fiber subunit may include multiple optical fibers (such as 250 um or 900 um). In order to connect conductors and/or fibers directly to the RRH, optical fiber and power conductors are separated from the hybrid cable as individual jumpers, the jumpers protected with separate furcation tubes.
[0051] A transition housing 1, for example as shown in FIGS. 1-15 , surrounds the transition of the hybrid cable to the furcation tubes. The transition housing 1 may be provided, for example, as a polymer or metal material housing with a cable portion 3 (FIGS. 3 and 4 ) and a furcation portion 5 (FIGS. 5-7 ) that mate within one another to enclose a break-out area 7 (best shown in FIGS. 8-11 ). The transition housing 1 may be formed, for example, by injection molding, machining and/or insert molding.
[0052] The cable portion 3 includes a cable port 9 dimensioned to receive the hybrid cable. The cable port 9 may be dimensioned to enable the cable portion 3 to be drawn over the cable end and any shielding and/or outer jacket of the hybrid cable during installation to allow mounting the furcation portion 5 close to the end of the outer jacket. The cable portion 3 can then be drawn toward the seated furcation portion 5 for sealing of the furcation area 7. The mating between the cable and furcation portions 3, 5 may be, for example, via threads, interference and/or snap fit, or alternatively via fasteners such as screws or bolts. The cable and/or furcation portions 3, 5 may include one or more adhesive ports 11 for injecting an adhesive and/or sealant into the furcation area 7 and/or exhausting these areas as the adhesive and/or sealant is applied.
[0053] The adhesive may be an epoxy with elastomeric properties.
[0054] The furcation portion 5 may include one or more conductor ports 13 and fiber ports 15. The conductor ports 13 may be dimensioned to receive conductor furcation tubes therethrough, into the furcation area 7.
[0055] The conductor furcation tubes 27 may include, for example, an inner tube 29, a metallic shield layer 31 and outer jacket 33, for example as shown in FIG. 16 . Shielded conductor furcation tubes 27 are described in detail in commonly owned U.S. patent application Ser. No. 13/791,248, titled “Shielded Electrical Conductor Furcation Assembly” filed 8 Mar. 2013 by Nahid Islam, hereby incorporated by reference in its entirety. The fiber furcation tubes 35 may include, for example, an inner jacket 37, a fiber and strength layer 39 and an outer jacket 33, for example as shown in FIG. 17 . Damage-resistant fiber furcation tubes 35 are described in detail in commonly owned U.S. patent application Ser. No. 13/832,131, titled “Rugged Furcation Tube” filed 15 Mar. 2013 by Nahid Islam, hereby incorporated by reference in its entirety. For example, each fiber furcation tube 35 may be dimensioned to receive either 900 um or 250 um optical fibers. Further, each fiber furcation tube 35 may include multiple inner tubes 29, within the inner jacket 37, for separate fibers and/or fiber bundles. The inner tubes 29 may be dimensioned to pass through the fiber ports 15, into the fiber area 19, as shown for example in FIG. 18 .
[0056] The fiber ports 15 may be dimensioned with a furcation shoulder 17 (see FIG. 6 ) dimensioned to seat the fiber and strength layer 39 and/or outer jacket 33 of a fiber furcation tube 37, the remainder of the fiber port 15 dimensioned to pass the fiber and/or fiber bundle therethrough. Several fiber ports 15 may be grouped together with an adhesive well 20 projecting from the furcation end 18, for adhering several fiber furcation tubes 35 further to one another, to increase a pull-off resistance characteristic of each individual fiber furcation tube and/or allow an increased amount of adhesive to be applied thereto, so that the furcation end 18 is provided with an elastomeric characteristic to protect the individual fiber furcation tubes 35 from buckling against a lip of the respective fiber ports 15.
[0057] The conductor ports 13 may also include a furcation shoulder 17 at the furcation end 18, to allow an increased amount of adhesive to be applied thereto, so that the furcation end 18 is provided with an elastomeric characteristic to increase a pull-off resistance characteristic and/or protect the conductor furcation tubes 27 from buckling against a lip of the conductor port 13.
[0058] The fibers 47 are isolated from the furcation area 7 to prevent their immobilization in adhesive injected within the furcation area 7. Thereby, the fibers 47 may be isolated from stresses generated by thermal expansion differentials that may exist between metal and/or polymeric portions of the assembly and the fibers. That is, the fibers 47 are free floating between the cable 43 and the fiber furcation tube 35.
[0059] The fiber area 19 (see FIGS. 8 and 9 ) wherein the individual fibers transition from the fiber bundle 45 of the cable 43 to their respective fiber furcation tubes 35 may be provided, for example, via an inner wall portion 24 that seats into a fiber area shoulder 21 (see FIG. 7-9 ) of the transition end 23 of the furcation portion 5 surrounding the fiber ports 15 and is sealed against a fiber bundle 45 of the cable 43 by an end stop 25 sealing between an outer jacket of the fiber bundle 45 and the inner wall portion 24. Where the inner wall portion 24 is cylindrical, the end stop 25 may be provided as a polymeric annular gasket or the like, seated sealing on an inner diameter against the outer jacket of the fiber bundle 45 and on an outer diameter against an inner diameter of a bore of the inner wall portion 24, as shown for example in FIGS. 12 and 13 . Alternatively, the inner wall portion 24 may be formed with, for example, a conical reduction proximate the transition end 23, wherein the transition end 23 has an inner diameter proximate an outer diameter of the outer jacket of the fiber bundle 45, for example as best shown in FIGS. 14 , 15 and 18. One skilled in the art will appreciate that the fiber bundle 45 may be a fiber subunit of the cable 43 which encloses a single fiber 47 or a plurality of fibers 47.
[0060] To manufacture an assembly, for example as shown in FIGS. 18-21 , the cable 43 has the outer jacket 33 and any shield 41 stripped back to expose desired lengths of the fiber 47, electrical conductors 49 and/or fiber bundles 45. The cable portion 3 is advanced over the conductors and over the outer jacket 33 of the cable 43 and the end stop 25 (if present) and inner wall portion 24 advanced over the fiber bundle 45. The furcation portion 5 is advanced over the conductors, each of the conductors and/or conductor bundles inserted to respective fiber and/or conductor furcation tubes 35, 27, the conductor furcation tubes 27 passed through conductor ports 13 and fiber furcation tubes 35 seated in their respective furcation shoulders 17, for example as shown in FIGS. 18 and 19 . The metallic shield layer 31 of the conductor furcation tubes 27 may be coupled to a drain wire and/or the shield 41 of the cable 43, for example via a shield interconnection, such as a tie wire, fastener, soldering or the like. The shield interconnection and fiber area 19 (inner wall portion 24 sealed against the transition end 23 of the furcation portion 25 by seating in the fiber area shoulder 21 and closed by the end stop 24) are enclosed by returning the cable portion 3 towards the furcation portion 5 and coupling them together (see FIG. 19 ).
[0061] The furcation area 7 may then be sealed/encapsulated by injecting a desired adhesive (also known as a sealant or caulk) into the adhesive port(s) 11 of the cable and/or furcation portions 3, 5, until the adhesive is observed, for example, at the cable port 9 and/or conductor ports 13. Further adhesive may be applied to seal the fiber furcation tubes 35 into the furcation shoulders 17 of the fiber ports 15 and the fiber furcation tubes 35 to one another within the adhesive well 20 of the furcation portion 5. Splaying a fiber portion of the fiber and strength layer 39 so that it extends within the furcation shoulder 17 and/or further into the adhesive well 20 (see FIG. 18 ) provides secure retention of the fiber furcation tubes 35 to the furcation portion 5 and thereby to the assembly.
[0062] The transition housing 1, individual conductor ports 13 and/or the adhesive well 20 may be further sealed by applying shrink tubing 69 or pultruded seals therearound, for example as shown in FIGS. 21 , 35 and 36.
[0063] The assembly may be further completed by applying desired connectors to each of the conductors at the end of their respective furcation tubes, as best in FIG. 21 .
[0064] A grounding lug may be applied to the transition housing and/or a grounding lead may be routed from the junction of the cable shield/drain wire and conductor furcation tube shields to the sidewall of the assembly (if conductive) or in a sealed fashion to an exterior of the assembly to provide a ready grounding point for the cable assembly.
[0065] In a further embodiment, the inner wall portion 24 may be provided with a fiber capsule cap 53 which includes the fiber port(s) 15, for example as shown in FIGS. 22 and 23 , The inner wall portion 24 and fiber capsule cap 53 mate together to form a fiber capsule 55 that encloses the fiber area 19, as shown in FIGS. 24 and 25 .
[0066] When a fiber capsule 55 is applied, the furcation portion 5 may be simplified to include a fiber capsule port 57, instead of the multiple fiber ports 15 and adhesive well features. The fiber capsule port 57 may include a fiber area shoulder 21 dimensioned to receive a stop rim 67 of the fiber capsule cap 53 or the inner wall portion 24, for example as shown in FIGS. 25 and 33 . Thereby, the manufacture of the furcation portion 5 is simplified by transferring the formation of the several small holes of the fiber ports 15 and associated surface features to a much smaller overall element, such as the fiber capsule cap 53, where the overall scale of the element is closer to that of the dimensions of the fiber port(s) 15, simplifying the corresponding mold and/or machining requirements. Further, multiple fiber capsule caps 53 may be cost efficiently manufactured/provided, with varying numbers of fiber ports 15 and or fiber port dimensions, to match the number and/or type of fibers 47 that are present in the desired cable assembly. Thereby, a single furcation portion 5 configuration may be utilized with a range of cables, including cables with different numbers and/or types of fibers 47.
[0067] The fiber capsule cap 53 may include an adhesive well 20 at the furcation end 18, as best shown in FIG. 23 . The furcation shoulders 17 of the fiber ports 15 may include sidewall slots 59 communicating between the furcation shoulders 17 of adjacent fiber ports 15. The sidewall slots 57 may enable additional intermingling and mutual reinforcement of splayed fiber portions of the fiber and strength layer 39 so that they extend deeply within more than a single furcation shoulder 17 and/or are distributed further about the adhesive well 20. The increased intermingling and/or distribution of the splayed fiber portions provide enhanced retention of the fiber furcation tubes 35 to the fiber capsule cap 53 and thereby to the assembly, upon application of adhesive to the adhesive well 20.
[0068] The furcation capsule 53 may be provided with one or more rotational interlock features, such as projections 58, on the outer diameter, for example provided on the fiber capsule cap 53 (see FIGS. 22 and 23 ), which key with corresponding sockets 60 provided in the sidewall of the fiber capsule port 57 (see FIGS. 26 and 27 ) to rotationally interlock the furcation capsule 53 with the furcation portion 5. Alternatively, the rotational lock features may be applied to the inner wall portion 24.
[0069] The furcation portion 5 has been demonstrated with the inner wall portion 24 and associated fiber area 19 provided off-center with respect to a cross-section of the furcation portion 5, for example for ease of assembly. Alternatively, in a trade-off with ease of assembly, the furcation portion 5 may be configured such that inner wall portion 24 or fiber capsule 55 seat is proximate a center of the furcation portion 5, with the conductor ports 9 arrayed there around. Thereby, the fiber furcation tubes 35 may be shielded from harm by the more robust conductor furcation tubes 27. Providing the conductor ports 9 grouped to leave an access area around a centrally positioned fiber capsule port 57, for example as shown in FIGS. 28 and 29 , provides a balance of protection and ease of assembly.
[0070] Manufacture of an assembly including a fiber capsule 55 is similar to the description of the previous embodiment except that the fibers inserted into the inner wall portion 24 are also passed through respective fiber ports 15 of the capsule cap 53 which is then seated upon the furcation end 18 of the inner wall portion to form the fiber capsule 55. The fibers are further passed through the fiber capsule port 57 and the fiber capsule 55 seated in the fiber capsule port 57.
[0071] The fiber capsule cap 53 may include a retention groove 61 on the outer diameter, positioned to seat a retainer 63 such as an o-ring, c-clip, snap ring or the like, to retain the fiber capsule 55 seated in the fiber capsule port 57 as the furcation portion 5 and cable portion 3 are mated together and encapsulating adhesive is applied to the furcation area 7. Where the retainer 63 is a clip or retaining ring, an environmental seal 65 may be applied to the outer diameter of the capsule cap 53 to seal external access to the furcation area 7 and/or prevent injected adhesive from leaking along the fiber capsule 55 and fiber capsule port 57 interconnection.
[0072] The fiber capsule port 57 enables initial preparation of the fiber area 19 and fiber furcation tubes 35, which are then passed through the fiber capsule port 57, simplifying assembly.
[0073] In a further simplification of the fiber capsule 55, the inner wall portion 24 may be adapted to seat within the fiber capsule port 57, without requiring application of a fiber capsule cap 53, for example as shown in FIGS. 30 and 31 . A inner wall portion 24 provided with an outer diameter stop rim 67 dimensioned to seat within the fiber area shoulder 21 seats the inner wall portion 24 within the fiber capsule port 57, but does not enable passage entirely therethrough. Similarly, a retention groove 61 may be provided proximate the furcation end 18 of the inner wall portion 24, for application of a retainer 63 to hold the inner wall portion 24 in place within the fiber capsule port 57, for example as shown in FIGS. 32 and 33 .
[0074] The fiber furcation tubes 35 may be encapsulated within the fiber area 7 as a sub-assembly ready for feeding the fiber furcation tubes 35 through the fiber capsule port 57 of the furcation portion 5, by filling the fiber area 7 with an adhesive, for example as shown in FIG. 34 .
[0075] Shrink tubing 69 may be utilized with a simplified inner wall portion 24, for example as shown in FIGS. 35 and 36 . In addition to sealing between the inner wall portion 24 and the fiber bundle 45, the leading edge of the shrink tubing 69, adhered to the inner wall portion 24, may provide the stop rim 67 which abuts the fiber area shoulder 21 and/or functions as a retainer 63 at the furcation end of the inner wall portion 24 to retain the inner wall portion 24 with respect to the furcation portion 5.
[0076] One skilled in the art will appreciate that the assembly provides a splice-free cable conductor distribution with significant pull-apart strength and improved environmental sealing in an assembly with minimal dimensions that eliminates the need for distribution boxes and/or on-site conductor termination during installation. Further, because the fibers 47 and/or electrical conductors 49 may lay freely within their respective inner tubes 29 from the transition housing 1 to the connector 51, the fibers 47 and/or electrical conductors 49 are free of thermal expansion and or tensile stress that may be applied to their respective fiber and conductor furcation tubes 35, 27.
