## Background
RELATED APPLICATIONS
This application claims the benefit of priority under 35 U.S.C. §119 of U.S. Provisional Application Ser. No. 61/770,823 filed on Feb. 28, 2013, the content of which is relied upon and incorporated herein by reference in its entirety.


BACKGROUND
1. Field of the Disclosure
The technology of the present disclosure relates to fiber optic connector adapter modules and, more particularly, to ganged fiber optic connector adapter module assemblies configured to be installed data center enclosures.
2. Technical Background
Benefits of optical fiber include extremely wide bandwidth and low noise operation. Connectors are often used in cable management systems to provide service connections to rack-mounted equipment and to provide inter-rack connections. Typical connectors for mating fiber optics include two connectors that are joined by an adapter. As one example of a connector, an MPO-style connector is a multi-fiber connector suitable for high-density backplane and printed circuit board (PCB) applications for data and telecom systems. MPO-style connectors generally utilize adapters, which align the MPO-style connectors with other multi-fiber connectors for forming a connection therebetween.
Fiber optic communication systems, such as fiber optic local area networks (LAN), for example, commonly include fiber optic data center equipment, such as racks, frames, sub-frames, or enclosures to provide for connection of a large number of connectorized optical fibers. In many applications, a large number of ports for receiving fiber optic connectors are provided in a single enclosure, which may be arranged according to a desired configuration. Assembly and/or reconfiguration of the ports in such data center equipment may be time consuming and costly.
SUMMARY OF THE DETAILED DESCRIPTION
Embodiments of the present disclosure allow for ganged fiber optic connector adapter module modules to be installed into a data center enclosure (e.g., a data center of a local area network (“LAN”) or the like) without the use of tools, thereby potentially reducing installation time and cost. More specifically, a fiber optic connector adapter module module may include multiple ports configured to mate with one or more fiber optic connector styles. The fiber optic connector adapter module modules may convert a first fiber optic connector style to a second fiber optic connector style employed in the data center enclosure.

DETAILED DESCRIPTION
Reference will now be made in detail to the embodiments, examples of which are illustrated in the accompanying drawings, in which some, but not all embodiments are shown. Indeed, the concepts may be embodied in many different forms and should not be construed as limiting herein; rather, these embodiments are provided so that this disclosure will satisfy applicable legal requirements. Whenever possible, like reference numbers will be used to refer to like components or parts.
Embodiments disclosed herein relate to fiber optic connector adapter module assemblies used in applications that include, but are not limited to, optical data center applications. More particularly, embodiments described herein may include one or more adapter mounts having a plurality of adapter openings for receiving one or more fiber optic connector adapter modules comprising an array of fiber optic connector adapters. The adapter mount(s) may be disposed in a data center enclosure to assist in the connection of fiber optic connectors for fiber optic data communication using light signals. Each adapter may include a plurality of fiber optic connectors of one or more styles to allow fiber optic connectors of fiber optic cable assemblies to be optically coupled to an optical network via the data center enclosure. For example, each adapter may include a plurality of MPO-style connector receptacles for receiving a plurality of optical cable assemblies having an MPO-style connector. It is noted that although embodiments are illustrated herein being directed to MPO-style connectors, embodiments are not limited thereto. The fiber optic connector adapter module assemblies described herein may be configured for other fiber optic connector styles.
As described in more detail below, embodiments allow for quick insertion of fiber optic connector adapter modules into a data center enclosure without the need for tools. The adapter mount may be installed in a data center enclosure (or other hardware) and allow for fiber optic connector adapter modules to be inserted by a twist-and-lock motion or a lateral translation motion. More specifically, the adapter mount includes a plurality of adapter openings having an insertion region that is dimensioned such that the fiber optic connector adapter module may pass through the adapter mount, and an installation region that is dimensioned such that the fiber optic connector adapter module is retained within the adapter mount upon movement from the insertion region to the installation region. Installation time and costs may be reduced because of the fiber optic connector adapter modules may be installed without the use of tools. Various embodiments of fiber optic connector assemblies and methods including twist-and-lock and linear insertion methods are disclosed in detail below.
Referring now to FIG. 1, a fiber optic connector adapter module assembly 100 according to one embodiment is illustrated. The fiber optic connector adapter module assembly 100 generally includes an adapter mount 101 and a plurality of fiber optic connector adapter modules 110 that are installed in adapter openings 102 of the adapter mount 101. The adapter mount 101 may be disposed in a data center enclosure (not shown), for example, to provide for optical connection of coupled optical cable assemblies to a data network (e.g., a local area network (“LAN”)). The fiber optic connector adapter modules 110, each of which includes an array of fiber optic connector adapters 108, are retained within the adapter openings 102 of the adapter mount 101. As described in more detail below, the fiber optic connector adapter modules 110 are installed by positioning the fiber optic connector adapter module 110 in an insertion region of the adapter opening 102, and then rotating the fiber optic connector adapter module 110 into an installation region of the adapter opening 102 where it is releasably retained by a retention mechanism.
FIGS. 2A and 2B depict a first side and a second side of an exemplary fiber optic connector adapter module 110, respectively. The fiber optic connector adapter module 110, which may be fabricated from a rigid material, such as molded plastic, includes an array of fiber optic connector adapters 108 including a plurality of first ports 111 (FIG. 2A) and a plurality of second ports 112 (FIG. 2B). The plurality of first ports and the plurality of second ports may define a plurality of port pairs. Referring first to FIG. 2A, the first ports 111 have a body 113 that are shaped to form an opening configured to releasably receive an MPO-style fiber optic connector 163 (see FIGS. 4 and 5). The first ports 111 may be configured to receive other fiber optic connector styles (e.g., SC or LC). Although the illustrated fiber optic connector adapter module 110 is depicted as having eight first ports 111, embodiments are not limited thereto.
Optionally, fiber optic connector adapter modules 110 of the present disclosure may further include at least one reinforcement member 120 disposed between adjacent first ports 111. The at least one reinforcement member 120 may be connected to adjacent first ports 111 to strengthen the fiber optic connector adapter module 110 by stiffening each first port 111. Accordingly, the at least one reinforcement members 120 may minimize any deflection, and therefore the amount of torque experienced by the first ports 111, under optical cable assembly loads caused by coupled fiber optic connectors 163.
In the illustrated embodiment, the at least one reinforcement member 120 comprises two equally spaced reinforcement members 120. However, in alternative embodiments, a single, centrally positioned reinforcement member 120 may be provided. Further, more than two reinforcement members 120 may be provided. Although not shown in FIG. 2B, one or more reinforcement members may be disposed between adjacent second ports 112. Such second port reinforcement members may be configured as the first port reinforcement members 120 depicted in FIG. 2A, for example.
The illustrated fiber optic connector adapter module 110 comprises engagement features 116A-116D that are configured to contact the adapter mount 101 when the fiber optic connector adapter module 110 is positioned in the installation region of the adapter opening 102, as described below. When the fiber optic connector adapter module 110 is positioned in the installation region of the adapter opening 102, the engagement features 116A-116D are pressed against the adapter mount.
In the illustrated embodiment, the fiber optic connector adapter module 110 has a first engagement feature extending from a first end 117, and a second engagement feature extending from a second end 119. The first engagement feature is configured as a first tab 116A at a first edge 114 and extending from the first end 117 of the fiber optic connector adapter module 110, and a second tab 116B at a second edge 118 and extending from the first end 117 of the fiber optic connector adapter module 110. The second engagement feature is configured as a third tab 116C at the first edge 114 and extending from the second end 119 of the fiber optic connector adapter module 110, and a fourth tab 116D at the second edge 118 and extending from the second end 119 of the fiber optic connector adapter module 110. It should be understood that embodiments are not limited to number and configuration of the engagement features 116A-116D depicted in the figures. For example, in an alternative embodiment, the first engagement feature may be configured as a single tab extending from the center of the first end 117 of the fiber optic connector adapter module 110, and the second engagement feature may be configured as a single tab extending from the center of the second edge 119 of the fiber optic connector adapter module 110. Other configurations are also possible.
Referring now to FIG. 2B, the fiber optic connector adapters 108 of the illustrated fiber optic connector adapter module 110 includes a plurality of second ports 112 opposing the plurality of first ports 111 to form a plurality of port pairs. The second ports 112 may face the interior of the data center enclosure when the fiber optic connector adapter module 110 is installed in the adapter mount 101, and be configured to receive a fiber optic connector that is to be coupled to the first fiber optic connector.
A ferrule element 180 may be disposed within each first port 111 (and/or second port 112), as shown in FIG. 3. The ferrule element 180 may take on a variety of configurations, and embodiments are not limited to the configuration of the ferrule assemblies depicted herein. As such, the ferrule element 180 is provided for illustrative purposes only. In the illustrated embodiment, the ferrule element 180 comprises an optical interface 182 that is defined by an array of lens elements, which are optically coupled to fiber optic components (not shown), such as optical fibers or waveguides extending toward a rear opening of the second port 112 (see FIG. 5). The lens elements may be configured as refractive lenses, diffractive lenses, gradient-index (“GRIN”) lenses and the like, and be positioned to be optically coupled to mated lenses of the fiber optic connector inserted into a first port 111. The optical interface 182 may be positioned at a rear end of the enclosure defined by the body 113 of the first port 111. As described below with respect to FIG. 5, the ferrule element 180 may be configured to translate within the first port 111 and/or the second port 112.
The illustrated ferrule element 180 includes mechanical coupling features that are configured to mate with corresponding mechanical coupling features of a ferrule element of a fiber optic connector 163. The exemplary mechanical coupling features of the illustrated embodiment comprise an alignment pin 184 and an alignment bore 185. The alignment pin 184 may be inserted into an alignment bore of the fiber optic connector 163, and the alignment bore may receive an alignment pin from the fiber optic connector 163.
Referring now to FIG. 4, an exemplary optical cable assembly 160 having a fiber optic connector 163 configured to be inserted into one of the first ports 111 of the fiber optic connector adapter module 110 is depicted. It should be understood that the fiber optic connector 163 is provided for illustrative purposes only, and that embodiments are not limited to any type or configuration of fiber optic connector. The optical cable assembly 160 generally includes a fiber optic cable 161 that is coupled to a fiber optic connector 163 that is configured as a plug. The fiber optic cable 161 may include an outer jacket that surrounds and protects a plurality of optical fibers configured to optical transmission of optical signals. A strain relief element 162 may also be provided to protect the plurality of optical fibers from external forces applied to the optical cable assembly 160. The fiber optic connector 163 generally comprises a plug body 164 that defines a ferrule enclosure into which a recessed ferrule element 170 is disposed. Having the ferrule element 170 recessed within the plug body 164 protects the lens elements of the ferrule element 170 from damage.
The ferrule element 170 is configured to optically and mechanically mate with a ferrule element 180 of the fiber optic connector adapter module 110. In the illustrated, non-limiting example, the ferrule element 170 of the fiber optic connector 163 includes an optical interface 172 comprising an array of lens elements (which may be optically coupled to optical elements, such as optical fibers or waveguides). As described above, the lens elements may be configured as refractive lenses, diffractive lenses, GRIN lenses, and the like. The ferrule element 170 further includes an alignment pin 174 and an alignment bore 175 configured to mate with the alignment bore 185 and the alignment pin 184 of the ferrule element 180 within the fiber optic connector adapter module 110, respectively.
The exemplary fiber optic connector 163 includes a plug body opening 167 at an insertion surface 166, which is the surface of the plug body 164 that is inserted into the first port 111. The plug body opening 167 is configured to receive the mated ferrule element 180 the fiber optic connector 163 is coupled to the first port 111.
In the illustrated embodiment, the plug body 164 comprises a first latching arm 165A and a second latching arm 165B that extend from the insertion surface 166 and are offset from a main portion of the plug body 164. Although two latching arms are depicted, it should be understood that more or fewer may be provided in alternative embodiments. The illustrated first and second latching arms 165A, 165B include a detent 169 that act as a locking mechanism that is configured to engage openings 115 of the first port 111 when the fiber optic connector 163 is inserted into the first port 111. The first and second latching arms 165A, 165B may include a release tab 168 at an end that is distal from the insertion surface 166. The first and second latching arms 165A, 165B are compliant in a direction transverse to the insertion direction upon application of force applied to the release tabs 168.
FIG. 5 depicts a cross-sectional view of the exemplary fiber optic connector 163 inserted into a first port 111 of a fiber optic connector adapter module 110. Optical fibers are not shown in FIG. 5 for clarity and ease of illustration. The ferrule element 180 within the first port 111 (“port ferrule element”) in the illustrated embodiment is biased from an enclosure defined by the second port 112 toward an enclosure defined by the first port 111 by a bias member 187. The bias member 187 may be configured as a spring, for example. Accordingly, the port ferrule element 180 may translate within the fiber optic connector adapter module 110 upon insertion and removal of the fiber optic connector 163. The bias member 187 is maintained within the enclosure defined by the second port 112 by a clip element 190 in the illustrated embodiment. Other configurations are also possible.
The ferrule element 170 within the enclosure defined by the fiber optic connector 163 (“plug ferrule element”) mates with the port ferrule element 180 when the fiber optic connector 163 is inserted into the first port 111 in a direction indicated by arrow A. As shown in FIG. 5, the plug ferrule element 170 and the port ferrule element 180 may each include fiber bores 178, 188 in which optical fibers (or waveguides and/or other optical components) may be disposed. The optical fibers (not shown) may terminate at the respective optical interface 172, 182, or terminate at some other optical components within the plug ferrule element 170 and the port ferrule element 180 (e.g., GRIN lenses or waveguides).
The fiber optic connector 163 may be inserted into the first port 111 until the detents 169 of the first and second latching arms 165A, 165B are positioned in the openings of the body 113 of the first port 111. The alignment pin 174 of the plug ferrule element 170 is inserted into the alignment bore 185 of the port ferrule element 180, and the alignment pin 184 of the port ferrule element 180 is inserted into the alignment bore 175 of the plug ferrule element 170. In this manner, the alignment pins 174, 184 and the alignment bores 175, 185 provide fine alignment of the lens elements of the two coupled optical interfaces 172, 182. The plug ferrule element 170 may push the port ferrule element 180 along direction A such that the bias member 187 applies a force on the plug ferrule element 170 to maintain optical coupling between the optical interfaces 172, 182.
It should be understood that other connectors and coupling configurations may be provided, and that the embodiments depicted in at least FIGS. 4 and 5 are used merely as examples.
Referring now to FIG. 6A, a second surface 103 (i.e., rear surface that faces the internal components of the data center enclosure) of an adapter mount 101 according to one embodiment is illustrated. The adapter mount 101, which may be fabricated from any suitably rigid material, such as metal, includes a plurality of adapter openings 102 into which a plurality of fiber optic connector adapter modules 110 may be inserted. The number of adapter openings 102 may depend on the type and/or area of the data center enclosure the adapter mount 101 is to be installed. The illustrated adapter mount 101 includes 13 adapter openings 102; however, more or fewer adapter openings 102 may be included. The adapter mount 101 may be configured to be installed in a data center enclosure by any number of methods. The attachment method may depend on the end application.
Each adapter opening 102 may have at least one retention mechanism associated therewith. The retention mechanism is configured to retain the fiber optic connector adapter module 110 in the installed position within the adapter opening 102. In the illustrated embodiment, the retention mechanism is configured as two spring clips 130. One spring clip 130 is located proximate a first, top end of the adapter opening 102, while another spring clip is located proximate a second, bottom end of the adapter opening 102. The spring clips 130 of the illustrated embodiment are located on opposite sides of the adapter opening 102. The spring clips 130 may be fabricated from metal, for example, and be coupled to the second surface 103 of the adapter mount 101 by any appropriate means (e.g., welding, adhesive, solder, fasteners, and the like). It should be understood that the spring clips 130 may be made of materials other than metals. The retention mechanism(s) may take on other configurations, as described in more detail below.
FIG. 6B is a close-up view of a single adapter opening 102. As stated above, the adapter opening 102 comprises an insertion region 140 and an installation region 141. The insertion region 140 is larger than the installation region 141, and is dimensioned to accept the fiber optic connector adapter module 110. In other words, at least a portion of the fiber optic connector adapter module 110 may pass through the adapter opening 102 at the insertion region 140. The insertion and installation process according to one embodiment is described below with reference to FIGS. 7A-8. The insertion region 140 is angled with respect to the installation region 141, which is aligned with the γ-axis in FIG. 6B. Accordingly, the fiber optic connector adapter module 110 is inserted into the insertion region 140 at an angle θ with respect to the γ-axis and the installation region 141.
The shape of the adapter opening 102 may depend on the shape and configuration of fiber optic connector adapter module 110. The insertion region 140 should be larger than the installation region 141 such that the fiber optic connector adapter module 110 may be inserted into the insertion region 140 and then rotated such that it contacts a portion of the adapter mount 101 and is restricted from movement in three directions due to the shape of the installation region and/or any retaining mechanisms (e.g., spring clips 130). In the illustrated embodiment, the insertion region 140 of the opening is defined by a first angled edge 107A and a second angled edge 107B. The first and second angled edges 107A, 107B are angled by an angle θ with respect to the γ-axis and are parallel with respect to one another. The first angled edge 107A transitions into a first straight edge 108A that is opposite from the second angled edge 107B, and defines a portion of the installation region 141. The second angled edge 107A transitions into a second straight edge 108B that is opposite from the first angled edge 107A, and defines a portion of the installation region 141. The first and second angled edges 107A, 107B are offset with respect to one another by a distance w1 that defines a width of the insertion region 140. The distance w1 should be greater than a width of the fiber optic connector adapter module 110 such that the fiber optic connector adapter module 110 may pass through the adapter opening 102 at the insertion region 140. The first and second straight edges 108A, 108B are offset with respect to one another by a distance w2 that is smaller than a width of the fiber optic connector adapter module 110.
Positioned at a first end 109A of the exemplary adapter opening 102 (i.e., a top end) are a first notch 106A and a second notch 106B, and positioned at a second end 109B of the adapter opening 102 (i.e., a bottom end) are a third notch 106C and a fourth notch 106D. The first through fourth notches 106A-106D are dimensioned and positioned to receive the first through fourth tabs 116A-116D when the fiber optic connector adapter module 110 is positioned in the insertion region 140. In the illustrated embodiment, the second and third notches 106B, 106C are angled by angle θ with respect to the γ-axis to accommodate the second and third tabs 116B, 116C, respectively. The notches 106A-106D define contact areas 143A-143D that are configured to contact the first through fourth tabs 116A-116D when the fiber optic connector adapter module 110 is positioned in the installation region 141 of the adapter opening 102.

Alternatively, more or fewer notches may be provided.
The illustrated fiber optic connector adapter module 210 includes an additional engagement plate 250 that is offset from the first and second engagement features 215A, 215B. Accordingly, a gap g is present between the engagement plate 250 and the first engagement feature 215A, and between the engagement plate 250 and the second engagement feature 215B. The engagement plate 250 contacts a first surface 104 of the adapter mount 101, while the first and second engagement features 215A, 215B contact the second surface 103 of the adapter mount 101.
FIGS. 10A-10B depict the installation of the fiber optic connector adapter module 210 into the adapter opening 102 of the adapter mount 101. The adapter mount 101 is the same adapter mount 101 that is depicted in FIGS. 7A-7C. First, referring to FIG. 10A, the fiber optic connector adapter module 210 is turned by the angle θ with respect to vertical (or another reference orientation, depending on how the adapter mount 101 is installed in the data center enclosure) such that the first, second, third, and fourth tabs 116A-116D (not visible in FIGS. 10A-10C) are aligned with the first, second, third and fourth notches 106A-106D of the adapter opening 102, respectively. Referring to FIG. 10B, the fiber optic connector adapter module 110 is moved into the insertion region 140 such that the tabs 116A-116D are disposed in the respective notches 106A-106D.
