[0001] CROSS-REFERENCE TO RELATED APPLICATIONS This application claims priority to U.S. patent application Ser. No. 17 / 591,281, entitled “Optical Connector Switches, Systems, and Methods,” filed Feb. 2, 2022, the entire contents of which are hereby fully incorporated by reference.
[0002] The present disclosure relates generally to systems and methods for connecting and disconnecting fiber optic cables in a network distribution system, and more specifically, in some embodiments, the present disclosure relates to systems and methods for connecting and disconnecting an optical connection between a fiber optic input cable and a fiber optic output cable using a fiber optic connector that includes a built-in switch. [Background technology]
[0003] A fiber optic network distribution system typically includes multiple fiber optic cables that may be from multiple service providers. The fiber optic cables are configured to carry data in the form of optical signals, and therefore require special connections at the termination point of each fiber optic cable to ensure that the optical signals are properly transmitted. The fiber optic cables can carry optical signals from a point or source, such as a service provider, to a point of use, such as a data center network cabinet or patch panel. Each point of use may house multiple fiber optic cables and connection points.
[0004] To connect or disconnect service to a user or to switch service providers at a service point, the fiber optic cables may be spliced or terminated with connectors or types of couplers that require a technician to manually insert and / or remove the necessary fiber optic cables from the service point. Furthermore, splicing and / or adding connectors / couplers to fiber optic cables typically requires specialized training and equipment, and even a relatively simple service provider switching service may require a significant amount of time to complete.
[0005] Thus, all of the above-mentioned conventional systems suffer from shortcomings that continue to make connect / disconnect and switching difficult for service providers that use fiber optic cables.The present disclosure overcomes one or more shortcomings in the art. Summary of the Invention

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0016] For the purposes of promoting an understanding of the principles of the invention, reference will be made to certain embodiments or examples illustrated in the drawings and specific language will be used to describe the same, it being understood, however, that no limitation on the scope of the invention is intended. Alterations and further modifications of the described embodiments, and further applications of the principles of the invention as described herein, are contemplated as would normally occur to one skilled in the art to which the invention pertains.
[0017] 1 is a schematic diagram of an exemplary fiber optic network 100. The fiber optic network 100 may be utilized to transmit data, such as Internet service, television service, telephone service, or other services transmitted over or utilizing the fiber optic network, to data consumers, such as customers. In an exemplary embodiment, a central distribution office 102 or optical line terminal (OLT) provides optical signals to a number of fiber optic cables 104. The optical signals travel through the fiber optic cables 104 to a passive optical splitter 106. The passive optical splitter 106 splits the optical signals into the number of fiber optic cables 104 and directs them to at least one of another passive optical splitter 106, a street cabinet 108, and a multiple dwelling unit (MDU) 110. The fiber optic cable 104 exiting the second passive optical splitter 106 can be routed to, for example, at least one of a modem, an optical network terminal (ONT), or an optical master unit (OMU) 112 and a wireless ONT 112 for use by a customer 114. The fiber optic cable 104 exiting the street cabinet 108 can be routed directly to a customer 114. The MDU 110 can provide multiple services to multiple customers 114. The customers 114 can include single-family homes, apartments, condominiums, offices, other tenants, or other types of customers. In some implementations, multiple services can be provided to different floors in an office building or different offices in an office building.
[0018] 2 is a schematic diagram of another exemplary fiber optic network 200. A plurality of fiber optic cables 202 extend between a plurality of service locations 204. In this exemplary embodiment, a distribution bank 206, which may be housed in a distribution box or other enclosure, is located at each branch of the plurality of fiber optic cables 202. The distribution bank 206 is configured to hold a plurality of fiber optic connectors 208, each configured to facilitate quickly and efficiently switching service to the service locations 204 from a disconnected state to a connected state without requiring splicing or other types of modification of the fiber optic cables 202. Additionally, the fiber optic connectors 208 can facilitate switching between service providers without requiring splicing or other types of modification of the fiber optic cables 202.
[0019] 3 is a front view of one of the distribution banks 206 shown in FIG 2, illustrating multiple fiber optic connectors 208 grouped together within the distribution bank 206. In this exemplary embodiment, fiber optic cables 202 enter the distribution bank 206 via connectors 210, which may be waterproof, coupled to the distribution bank 206 and are distributed to multiple fiber optic connectors 208 to facilitate connection / disconnection of services.
[0020] 4-7, the fiber optic connector 208 includes a body 300, an input coupling 302, an output coupling 304, a shuttle 306, and a selector 308. In this example, the body 300 includes an upper cassette housing 310 and a lower cassette housing 312 configured to couple to one another via a snap-fit connection, defining an internal cavity 314 therebetween. The output coupling 304 is positioned opposite the input coupling 302, and each of the output coupling 304 and the input coupling 302 extends through a portion of the lower cassette housing 312. The selector 308 is connected to the shuttle 306 and extends through a portion of the upper cassette housing 310.
[0021] FIG. 6 shows an exploded view of the shuttle 306 and the input coupling 302. In this embodiment, the shuttle 306 includes a body, such as a connector body, that is physically displaced axially toward and away from the output 304. In the illustrated embodiment, the shuttle translates within the lower cassette housing 312 to bring the optical fiber of the output coupling 304 into optical communication with the optical fiber of the input 302. Depending on the embodiment, the shuttle 306 is a body that can be physically displaced either axially, laterally, or at an oblique angle to optically connect the input coupling 302 and the output coupling 304. Furthermore, in this embodiment, the shuttle 306 and the input coupling 302 are coupled together and operate as a single assembly. Further, in this embodiment, the shuttle 306 and the input coupling 302 include a connector housing 316, a split sleeve 318, a ferrule 320, and a coupling sleeve 322. The coupling sleeve 322 is configured to be positioned in a snap-fit relationship over the ferrule 320 such that the ferrule 320 is retained within the connector housing 316. The connector housing 316 is sized and configured to receive a fiber optic cable including at least one of a small form factor (SFF) connector and a multi-fiber connector. In some implementations, the connector housing 316 can be configured to receive an SFF connector including, for example, an MT-RJ connector, a VF-5 connector, an LC connector, an Opti-Jack connector, an SC-DC connector, and an SC-QC connector. In some embodiments, the connector housing 316 can be configured to receive a multi-fiber connector including, for example, a multi-fiber push-on (MPO) connector. In additional implementations, the connector housing 316 can be sized and configured to receive any type of connector that facilitates operation of the fiber optic connector 208 as described herein.
[0022] 7 illustrates an exploded view of the output coupling 304. In this embodiment, the output coupling 304 is an LC-type duplex adapter and includes a spring 324, a dust shutter 326, a lower housing 328, an upper housing 330, a split sleeve 332, an inner housing 334, and a light protection shutter 336. In this embodiment, the upper housing 330 of the output coupling 304 can be sized and configured to accept an SFF connector, including, for example, an MT-RJ connector, a VF-45 connector, an LC connector, an Opti-Jack connector, an SC-DC connector, and an SC-QC connector. In some embodiments, the output coupling 304 can be configured to accept a multi-fiber connector, including, for example, a multi-fiber push-on (MPO) connector. In additional embodiments, the output coupling 304 can be sized and configured to accept any type of connector that facilitates operation of the optical fiber connector 208 as described herein.
[0023] In this embodiment, referring to FIG. 8, the selector 308 includes a lever 338, a pivot rod 340, a biasing member 342, and a lever cap 344. The upper cassette housing 310 includes an internal cam profile 346 (shown in FIGS. 9A-9E) configured to interface with a cam 348 of the lever cap 344, as described below. The biasing member 342 is received within a cavity of the lever 338 and is retained within the cavity by the lever cap 344. The lever cap 344 is configured to be received along an outer profile of a portion of the lever 338 to define a cavity. The biasing member 342 exerts a force against the lever cap 344, biasing the lever cap 344 radially outward. The pivot rod 340 interfaces with the upper cassette housing 210, and the lever 338 rotates about the pivot rod 340.
[0024] 9A-9E show partial schematic views of a selector 308 in multiple operating positions. In this embodiment, the selector 308 may be a toggle switchable between two or more different positions that optically connect the input coupling 302 and the output coupling 304 of the fiber optic connector 208. With reference to FIG. 8 and FIGS. 9A-9E, the selector 308 is configured to move between an "on" position 350 and an "off" position 352, which represent optically connected and optically disconnected positions, respectively. In this embodiment, a shuttle 306 is coupled to the input coupling 302, and moving the selector from the off position 352 to the on position 350 moves the shuttle 306 and the input coupling 302 from a disconnected position 354 to a connected position 356. More specifically, to move the lever 338 from the OFF position 352 (shown in FIG. 9A) to the ON position 350 (shown in FIG. 9E), the lever cap 344 is pushed radially inwardly so that the cam 348 is radially inward of an adjacent transition portion of the internal cam profile 346 (shown in FIG. 9B) and allows the lever 338 to rotate toward the ON position 350 (shown in FIG. 9C). Once the lever 338 is in the ON position 350 (shown in FIG. 9D), the radially inward force acting on the lever cap 344 may be released and the lever cap 344 extends radially outwardly due to the radially outward force acting on the lever cap by the biasing member 342 (shown in FIG. 9E). The cam 348 rests against the ON position 350 portion of the internal cam profile 346 and the selector 308 is locked in the ON position 350. To move the selector 308 from the ON position 350 to the OFF position 352, the reverse action is performed.
[0025] 10A-10D show cross-sectional views of the fiber optic connector 208 in several operational configurations. With reference to FIG. 10A, the selector 308 is in an on position 350 and the shuttle 306 is in a disconnected position 354. Additionally, no fiber optic cable is received in either the input coupling 302 or the output coupling 304. The dust shutter 326 is in an extended position 358 and is biased toward the extended position 358 by the spring 324. In this embodiment, the dust shutter 326 is configured to prevent the ingress of dust and other debris into the internal cavity 314 when the fiber optic output cable 364 is not present in the output coupling 304. In some embodiments, the dust shutter 326 may be positioned proximate an exterior opening of the input coupling 302. With further reference to FIG. 10A, the light protection shutter 336 is in a blocking position 360 that blocks the transmission of light through the output coupling 304.
[0026] Figure 10B illustrates the fiber optic connector 208 with the selector 308 in the off position 352 and the shuttle 306 in the disconnected position 354. The fiber optic input cable 362 is received within the connector housing 316, and the split sleeve 318 and the ferrule 320 are configured to cooperate with the fiber optic input cable 362 to facilitate an optical connection between the ferrule 320 and the fiber optic input cable 362. As shown in Figure 10B, the fiber optic output cable 364 is not received within the upper housing 330 of the output coupling 304 of Figure 10B.
[0027] Figure 10C illustrates fiber optic connector 208 with selector 308 in off position 352, shuttle 306 in disconnected position 354, fiber optic input cable 362 received in connector housing 316, and fiber optic output cable 364 received in upper housing 330. As shown in Figure 10C, dust shutter 326 has been rotated from extended position 358 as compared to Figures 10A-10B as a result of fiber optic input cable 362 being received in upper housing 330.
[0028] 10D illustrates the fiber optic connector 208 with the selector 308 in the on position 350 and the shuttle 306 in the connection position 356. More specifically, the shuttle 306 and the input coupling 302 are moved longitudinally along a connector axis 366 of the fiber optic connector 208 by the selector 308 such that the ferrule 320 of the shuttle 306 is coupled in optical communication with the fiber optic input cable 362 and the fiber optic output cable 364. The position of the ferrule 320 in the connection position 356 facilitates the transmission of light between the fiber optic input cable 362 and the fiber optic output cable 364.
[0029] 10D, in this embodiment, a portion of the connector housing 316 is configured to interface with a portion of the input coupling 302. More specifically, a keyway 368 extends parallel to the connector axis 366 within the lower cassette housing 312 and interfaces with the connector housing 316 to slidably retain the connector housing 316 between the connected position 356 and the disconnected position 354. Furthermore, advancing the shuttle 306 and the input coupling 302 to the connected position 356 deflects the light protection shutter 336 away from the connector axis 366 to further facilitate the transmission of light along the connector axis 366 between the fiber optic input cable 362 and the fiber optic output cable 364. The reverse of the above process can be performed to optically disconnect the fiber optic input cable 362 and the fiber optic output cable 364.
[0030] 11 is a perspective view of a ganged fiber optic connector 208 including a plurality of each of the input couplings 302, the output couplings 302, and the selectors 308. The ganged fiber optic connector 208 may be configured to operate similarly to the fiber optic connector 208, but may be fabricated from a single upper cassette housing 310 and a single lower cassette housing 312, each formed to enclose a plurality of input couplings 302, a plurality of output couplings 304, and a plurality of selectors 308. In this embodiment, the ganged fiber optic connector 208 is shown to include most of the components from eight individual fiber optic connectors 208, but it should be understood that the ganged fiber optic connector may include any number of input couplings 302, output couplings 304, and selectors 308 that facilitate operation of the ganged fiber optic connector 208 as described herein. In some embodiments, a plurality of fiber optic connectors 208 may be coupled together to form the ganged fiber optic connector 208.
[0031] FIG. 12 illustrates a fiber optic connector 400 including a rack and pinion selector 402, a photodetector 404, and a fiber optic coupler 406 extending between the shuttle 306 and the output coupling 304. Many of the features of the fiber optic connector 400 are similar to those described above with respect to the fiber optic connector 208 and will not be repeated here. In this embodiment, the shuttle 306 includes a number of teeth 408 configured to interface with the rack and pinion selector 402, such that rotating the rack and pinion selector 402 from an off position to an on position advances the shuttle 306 into the input coupling 302, past the light protection shutter 336, and into interface with the fiber optic input cable (not shown).
