摘要： Methods of reducing and/or avoiding fiber ordering during preparations of a multi-fiber, fiber optic cable to provide a connectorized multi-fiber, fiber optic cable system, and related fiber optic cables and assemblies are also disclosed. The embodiments disclosed herein allow for a section of a multi-fiber, fiber optic cable to be prepared to form two or more connectorized fiber optic cables as part of a multi-fiber cable system without requiring specific fiber ordering in the fiber optic connectors. The natural ordering of the optical fibers in the fiber optic cable is fixed in place in at least one section of the fiber optic cable before the optical fibers are cut to form adjacent fiber optic connectors in the cable system. Thus, the fiber ordering between adjacent fiber optic connectors in the cable system will be the same even though the fiber ordering of the optical fibers was random during cable preparations.

摘要： Optical fiber ferrules (10, 20) for making optical or optical and electrical connections are disclosed, along with receptacle and plug fiber optic interface devices (60, 70) using the ferrules, and cable assemblies (6, 7) using the fiber optic interface devices. The optical fiber ferrules support optical pathways (14) and have front ends (12F, 22F) with mating geometries that facilitate a relatively high number of mating/unmating cycles. The ferrule is translatable within the enclosure (62e, 72e). Resilient members (75) provide the ferrule with forward-bias and rear-bias positions when the fiber optic interface device is un-mated and mated, respectively.

摘要： Fiber optic distribution cables and methods for manufacturing the same are disclosed. The methods present one or more optical fibers outward of the protective covering for distribution of the same toward the subscriber. In one method of making the fiber optic distribution cables, an indexing tube is provided for indexing a tether tube within the indexing tube for providing the distribution optical fiber with a suitable excess fiber length. In another method, a demarcation point is provided for inhibiting the movement (i.e., pistoning) of the distribution optical fiber into and out of the distribution cable. In still another method, one or more caps are provided for closing one or more the openings in the protective covering used for accessing the optical fibers within the fiber optic distribution cable. Additionally, other methods may include providing a fiber optic distribution cable having a dry construction and/or a non-round cross-section.

摘要： A ferrule assembly having highly protruding optical fibers and a corresponding method of efficiently, precisely and repeatedly fabricating the ferrule assemblies are provided. In this regard, a ferrule assembly is provided that includes a plurality of optical fibers extending at least about 3.5 μm beyond the front face. The end portions of the optical fibers of the ferrule assembly may also be substantially coplanar with the end portions of the optical fibers differing in position from one another by no more than 100 nm. The ferrule assembly may be efficiently fabricated by polishing the optical fibers to a desired protrusion without first grinding or polishing the optical fibers to be flush with the front face of the ferrule. The ferrule assembly may be even more efficiently fabricated in instances in which the ferrule includes at least one polishing feature, such as an outwardly extending pedestal or a recessed portion.

摘要： Embodiments for binding material processing of gradient index (GRIN) rods into GRIN lenses attachable to optical devices, components, and methods are disclosed. A cylindrical GRIN rod comprises an optical axis and a longitudinal axis at a center axis, where an index of refraction may be greatest at the optical axis. The GRIN rod includes GRIN lenses along the longitudinal axis. The GRIN lenses include a first optical surface and a second optical surface opposite the first optical surface. Separation processes and devices may separate the GRIN lenses from the GRIN rods and these processes may be automated. Other processes may polish the first and the second optical surfaces. A gripper may insert the GRIN lens into an optical device.

摘要： Embodiments disclosed herein include fiber optic connectors employing a movable optical interface connected by optical fibers to a fiber optic cable, components and methods. In one embodiment, the movable optical interface moves between an extended position for cleaning by the user of the movable optical interface and a retracted position to optically connect the fiber optic connector to an optical device in a mechanically-secure manner. Because the fiber optic cable employs the movable optical interfaces, embodiments described herein involve one or more fiber protection features to prevent optical fiber attenuation and/or damage to the end portions of the optical fibers.

摘要： A system for cleaning internal optical components of a fiber optic connector includes a source of cleaning medium such as compressed air connected to a cleaning tip. The cleaning tip has a body and a tongue that is configured to be inserted into the end of the fiber optic connector. Nozzles are formed on the tongue. The tongue may have features to open shutters and/or other protective features in the connector that normally protect the internal optical components. When the tongue is inserted into the end of the connector, the nozzles are positioned adjacent optical components to be cleaned and compressed air is delivered through the nozzles to clean the components. Backwash can be exhausted around the tongue or through the tongue to eject contaminants from the fiber optic connector.

A plug-type fiber optic interface (20) has an axially moveable multi-fiber ferrule (100) that supports optical fibers (52) or a combination of optical fibers and gradient-index lenses (600). A resilient member (150) serves to provide the ferrule with forward-bias and rear-bias positions relative to a recessed front end (22) of a housing (21). A fiber optic interface assembly (570) that includes mated plug and receptacle fiber optic interface devices (20, 320) is also disclosed.
