The present invention relates to communications cabling and, more particularly, to connectorized fiber optic cabling and methods for forming the same.
Fiber array connectors are commonly employed to terminate multi-fiber fiber optic cables. Such connectors require that the fibers of the cable be arranged in a row or side-by-side, aligned configuration. In some cases, multiple, stacked layers or rows of fibers may be used. One method for providing fibers so arranged is to use ribbonized cabling. However, ribbonized cabling may suffer from drawbacks in bendability and cost. Another method is to use loose tube fiber cabling, ribbonize a relatively long section (e.g., from about 2 to 8 inches) of the fibers and install furcation tubing and other components on the cabling. This method using furcation tubing may suffer from various drawbacks in cost, bendability, installation requirements, etc. For example, epoxy typically must be used to secure a transition between the cable and the furcation tubing.
According to embodiments of the present invention, a connectorized fiber optic cabling assembly includes a loose tube fiber optic cable and a connector assembly. The cable has a termination end and includes: an optical fiber bundle including a plurality of optical fibers; at least one strength member; and a jacket surrounding the optical fiber bundle and the at least one strength member. The connector assembly includes a rigid portion and defines at least one fiber passage. The connector assembly is mounted on the termination end of the cable such that the optical fiber bundle extends through at least a portion of the at least one fiber passage. The plurality of optical fibers of the optical fiber bundle have a ribbonized configuration in the rigid portion of the connector assembly and a loose, non-ribbonized configuration outside the rigid portion. The plurality of optical fibers undergo a transition from the ribbonized configuration to the loose, non-ribbonized configuration in the rigid portion of the connector assembly. According to some embodiments, the rigid portion of the connector assembly includes a rigid connector housing.
According to method embodiments of the present invention, a method for forming a connectorized fiber optic cabling assembly includes providing a loose tube fiber optic cable having a termination end and including: an optical fiber bundle including a plurality of optical fibers having a loose, non-ribbonized configuration; at least one strength member; and a jacket surrounding the optical fiber bundle and the at least one strength member. The method further includes mounting a connector assembly including a rigid portion and defining at least one fiber passage on the termination end of the cable such that the optical fiber bundle extends through at least a portion of the at least one fiber passage, and such that the plurality of optical fibers of the optical fiber bundle have a ribbonized configuration in the rigid portion of the connector assembly and a loose, non-ribbonized configuration outside the rigid portion, and the plurality of optical fibers undergo a transition from the ribbonized configuration to the loose, non-ribbonized configuration in the rigid portion of the connector assembly. According to some embodiments, the rigid portion of the connector assembly includes a rigid connector housing.

The cable 20 may be a breakout or subunit cable from a larger cable including multiple cable subunits and one or more additional jackets. According to some embodiments, the cable 20 is constructed as disclosed in co-assigned U.S. patent application Ser. No. 11/412,616, filed Apr. 27, 2006, entitled Fiber Optic Cables and Methods for Forming the Same, the disclosure of which is incorporated herein by reference.
As shown in
An exemplary one of the optical fibers 42 is shown in cross-section in
According to some embodiments and as illustrated, the optical fiber 42 is an optical fiber constructed as commonly referred to as a “bare optical fiber” or a “non-buffered optical fiber”. According to some embodiments, the overall diameter D1 of the optical fiber 42 is in the range of from about 235 to 265 μm. According to some embodiments, the thickness TI of the coating layer 44 is no greater than about 70.5 μm. According to some embodiments, the overall diameter D1 is between about 235 to 265 μm and the thickness TI of the coating layer 44 is no greater than about 70.5 μm. According to some embodiments, the diameter D2 of the core 43A is between about 6 and 64 μm and the diameter D3 of the cladding 43B is between about 115 and 135 μm.
As shown, the bundle 50 of the strength yarns 52 at least partially surrounds the optical fiber bundle 40. The strength yarns 52 may be formed of any suitable material. According to some embodiments, the strength yarns 52 are aramid fibers. Other suitable materials may include fiberglass or polyester. According to some embodiments, the strength yarns 52 each have a denier in the range of from about 250 to 3000. According to some embodiments, the strength yarn bundle 50 includes between about 2 and 10 ends or strands of the strength yarns 52 (which may each include hundreds of filaments).
The jacket 60 surrounds the yarn bundle 50 and the optical fiber bundle 40, which reside in a longitudinal passage defined in the jacket 60. The jacket 60 may be formed of any suitable material such as a polymeric material. According to some embodiments, the jacket 60 is formed of a thermoplastic polymer. According to some embodiments, the thickness of the jacket 60 is between about 0.20 and 1.0 mm. According to some embodiments, the outer diameter D4 (
According to some embodiments, the inner diameter of the jacket passage is greater than the combined cross-sectional diameter of the optical fiber bundle 40 and the strength yarn bundle 50 so that at least the optical fibers 42 are loose and able to float within the jacket passage (i.e., move freely with respect to the jacket 60). According to some embodiments, both the optical fibers 42 and the strength yarns 52 are loose and can float within the jacket passage (i.e., can move freely with respect to the jacket 60). Thus, at least a portion of the volume of the jacket passage is not filled by the optical fibers 42 or the strength yarns 52 to allow movement of the optical fibers 42 and the strength yarns 52 within the jacket passage. The cable 20 may be referred to as a “round, loose tube cable”. According to some embodiments, a non-round (e.g., oval) loose tube fiber optic cable can be employed instead.

As shown in
According to some embodiments, the ribbonized section 40A has a length L1 (
With reference to
Termination of the connector assembly 100 on the cable 20 in accordance with embodiments of the present invention may be regarded as a round, loose tube fiber cable to array connector direct termination. The connector assembly 100 receives a round, loose tube fiber cable section and the fiber bundle of the round, loose cable section is converted or reconfigured to a ribbonized fiber bundle within the rigid portion R1 of the connector assembly 100. Thus, the entirety of the ribbonized fiber section 40A is contained in the rigid portion R1. Thus, according to some embodiments, none of the ribbonized fiber bundle is located where it can be bent in use. This termination allows for the benefits of round, loose fiber cabling up to the connector termination. For example, as compared to ribbon cable or a cable furcation assembly, a round, loose cable segment may be easier to bend, may be bendable with less loss of cable performance, and may have less or no preferential bending limitations. Moreover, termination in accordance with embodiments of the present invention may obviate the need for furcation tubing and the related expense, mess and effort.
The strain relief boot passage 162 has a rear section 162A that is round in cross-section (I.e., cylindrical) and properly sized to complement the round cable 20. In this way, the strain relief boot 160 may properly engage the directly terminated round cable to provide suitable strain relief thereto.
According to some embodiments, the connectorized cabling 10 is a cabling or cordage as shown in
Connectorized cables in accordance with embodiments of the present invention such as the connectorized cabling 10 may be formed using methods in accordance with embodiments of the present invention. According to some embodiments, the connectorized cable 10 can be assembled as follows.
The strain relief boot 160, the crimp sleeve 150 and the rear housing 140 are slid onto the cable 20 and out of the way as shown in
As also shown in
The fiber bundle 40 is then ribbonized using any suitable technique. According to some embodiments and with reference to

With reference to
The strain relief boot 160 is then slid forward on the cable 20 until the retention tabs or ribs 166 engage the front edge of the crimp sleeve 150.
According to some embodiments, the foregoing procedure is executed in a factory.
While a single layer ribbonized fiber section is provided in the illustrated embodiments, according to some embodiments, the ribbonized section may include multiple, stacked rows of the fibers in side-by-side alignment.
According to further embodiments of the present invention, methods of forming connectorized cables are provided in which a fiber optic cable 20′ is connectorized without the use of any tape (such as tape 70 of

Next, a thermal heat stripping tool (or other appropriate device) is used to strip the fiber coating layer 44 from the end sections of the fibers 42 that extend beyond the fiber alignment tool 200. In this manner, a bare fiber section 41A is formed that has a ribbonized configuration. In other embodiments, the ferrule boot 130 may be slid onto the fibers 42 (in the manner discussed below) before this stripping operation is performed.
With reference to
Pursuant to the above-described termination method, the fiber alignment tool 200 may be used to hold the fibers 42 in proper alignment until after the epoxy 128, the bare fiber section 41A and the ferrule boot 130 are inserted into the ferrule 120 and the epoxy 128 cured, thereby allowing the operation of adding a tape 70 or liquid adhesive to the exposed fibers 42 to be omitted. Here, the fibers 42 are in ribbonized configuration within the ferrule boot 130, but have a loose fiber configuration immediately behind the ferrule boot 130.
It will be appreciated that other configurations of connector assemblies may be employed. For example, the ferrule pins 132 may be omitted to form a female connector assembly for use with the male connector assembly 100 as illustrated. The pins 132 of the male connector assembly 100 may be received in the pin holes of the female connector assembly to facilitate alignment between the respective mating fiber ends. The male and female connector assemblies may be held together by an adapter, for example.
The foregoing is illustrative of the present invention and is not to be construed as limiting thereof. Although a few exemplary embodiments of this invention have been described, those skilled in the art will readily appreciate that many modifications are possible in the exemplary embodiments without materially departing from the novel teachings and advantages of this invention. Accordingly, all such modifications are intended to be included within the scope of this invention. Therefore, it is to be understood that the foregoing is illustrative of the present invention and is not to be construed as limited to the specific embodiments disclosed, and that modifications to the disclosed embodiments, as well as other embodiments, are intended to be included within the scope of the invention.
