The present disclosure provides an optical fiber and a method of fabricating an optical fiber. The method includes providing an optical fiber, the optical fiber defining a length having a proximal end and a distal end. The optical fiber includes a first core profile zone defining a first core diameter, and a second core profile zone defining a second core diameter different from the first core diameter. The optical fiber includes a first transition zone connecting the first core profile zone to the second core profile zone. The first core profile zone, the second core profile zone, and the first transition zone are formed as a single, continuous fiber.

Continuously formed optical fiber with different core profile zones

The present disclosure provides improved optical devices (e.g., discrete passive optical devices), and improved systems/methods for fabricating such optical devices. Systems/methods are provided for fabricating discrete passive optical devices by utilizing an advantageous cyclic core variance fabrication process/method. The cyclic core variance process/method employs a continuous process, but instead of having one constant core profile of the optical fiber, the core profile of the optical fiber varies cyclically, going back and forth between two or more core profile zones, with a gradual and properly-shaped transition zone in between. The core profile zones and transition zone can be custom formed (e.g., user-defined) to fabricate a variety of optical effects of the optical devices as desired, allowing a large variety of optical devices to be fabricated utilizing the exemplary cyclic core variance process/method.

Systems and methods for angle polishing of the end faces of a plurality of optical connectors are provided. Systems are provided that include a connector defining a longitudinal axis, and at least two ferrules mounted with respect to the connector and arranged in a side-by-side orientation. The end faces of the connectors are movable relative to the connector and such movement facilitates lateral orientation of the angle polished end faces of the ferrules relative to the connector when in the mating position. Various mechanisms and methods for facilitating movement of the ferrules relative to the connector are disclosed to achieve the desired lateral polish orientation of the ferrule end faces.

The multichannel fiber optic connector, adapter, and contact retention method is disclosed. The connector includes a load carousel which enables handling, locating, retention, and, where needed, spring-loading of the plurality of single-fiber fiber optic ferrules supported within the connector, and the connector itself provides for independent axial and radial alignment of the fiber optic contacts. The adapter includes a plurality of optical alignment sleeves, and mating interfaces for two different connector types on differing sides of the adapter, wherein the fiber count of one connector type is an integral multiple of the fiber count of the other connector type, and wherein the contact pattern of the first connector type is repeated the same integral number of times within the contact pattern of the second connector type. The contact retention method is achieved by means of a load carousel, which provides a devoted location for each of the plurality of single-fiber fiber optic ferrules it supports, and which, when necessary, provides an independent spring member for each ferrule, and which allows both terminated and unterminated ferrules to be assembled therein, and which further enables assembly into a connector or connector housing.

Improved cable management assemblies and related methods of use are provided. The present disclosure provides advantageous systems for the design and use of splice managers configured to provide for user-friendly access for the splicing of media cables (e.g., optical fiber cables), while also providing for the management and storage of the spliced cables. An exemplary splice manager includes two integral spools, the splice manager being removable from the assembly housing (e.g., from the splice cassette/tray) to allow for the splicing of the fibers to be performed out in the open, and then enable the fiber excess from both the input cable and the fiber harness of the assembly housing to be spooled independently of one another on a respective spool, and then allow the splice manager to be re-mounted to the assembly housing (e.g., within the enclosure space of the splice cassette).

Splice managers and related methods of use

The present disclosure provides improved color-coded labels, and improved systems and methods for utilizing such color-coded labels. More particularly, the present disclosure provides advantageous systems/methods for utilizing printable color-coded pattern label arrays for patch field applications and the like. The present disclosure provides improved methods for labeling data center applications (e.g., patch field applications). In exemplary embodiments, by fabricating a pre-printed, repeating pattern of the colors defined by industry specification TIA-598 to a roll/sheet of printable labels, this color coding can be advantageously applied to an array of patch field labels. Once the individual labels are printed and applied, the individual label color will translate to a sub-unit fiber number, while the overall array of label colors will reveal the panel polarity, which is important service information, which will be delivered in an immediate visual color-coded manner to the servicing technicians without the need for additional text.
