The present disclosure relates to a process by which an optical fiber array is cleaved with a laser-cleaving apparatus. The coating material is stripped or removed from a section of an optical fiber array; a coated or ribbonized section of the optical fiber array is secured in a holder; the holder is aligned inside the laser-cleaving apparatus; the laser cleaves the stripped ends of the fibers in the optical fiber array; the laser-cleaved ends of the optical fibers are then mechanically separated to remove the free ends from the optical fibers in the optical fiber array, leaving a cleaved array of optical fibers. The cleaving process enables the optical fiber array to be cleaved at flexible locations along an optical fiber ribbon or optical fiber cable with no swelling, minimal cleave angle variation across the cores of the optical fibers, a controlled surface roughness of the optical fiber end-faces, and high process yield.

Laser-cleaving of an optical fiber array with controlled cleaving angle

The present disclosure relates to a polymeric overcoating used as a splice protector, and a corresponding method of application where the resulting coated fusion spliced optical fibers or coated fusion spliced optical fiber ribbons can be bundled or stacked to reduce the size of splice protection.

Coating fusion spliced optical fibers and subsequent processing methods thereof

The present disclosure relates to a process by which an optical fiber array or a single optical fiber is cleaved with a laser-cleaving apparatus. The coating material is stripped or removed from a section of an optical fiber array or single optical fiber; a coated or ribbonized section of the optical fiber array or the single optical fiber is secured in a holder; the holder is aligned inside the laser-cleaving apparatus; the laser cleaves the stripped ends of the fibers in the optical fiber array or the single optical fiber; the laser-cleaved ends of the optical fiber(s) are then mechanically separated to remove the free ends from the optical fibers in the optical fiber array or the single optical fiber, leaving a cleaved array of optical fibers or a single cleaved optical fiber. The cleaving process enables the optical fiber array or single optical fiber to be cleaved at flexible locations along an optical fiber ribbon, optical fiber, or optical fiber apparatus (e.g., cleaving can be performed close to a ferrule end face) with no swelling, minimal cleave angle variation across the cores of the optical fibers, a controlled surface roughness of the optical fiber end faces, and high process yield.

Fiber optic connectors and other structures that can be easily and quickly prepared by the craft for termination and/or connectorization in the field are disclosed. More specifically, the fiber optic connectors and other structures disclosed are intended for use with glass optical fibers having a large core. In one embodiment, the fiber optic connector includes a ferrule having a bore sized to receive an optical fiber and a buffer layer at a front end face of the ferrule. Methods of making the fiber optic connectors and other structures are also disclosed. The methods disclosed allow 'rough cutting' of the optical fibers with a buffer layer thereon by the craft.

Fiber optic connectors and structures for large core optical fibers and methods for making the same

According to at least one exemplary embodiment a ferrule, comprises: (i) a bore extending from a rear of the ferrule to a front of the ferrule, wherein the bore is sized to receive an optical fiber and a buffer layer at one end face of the ferrule; and (ii) an end stop sized to engage the buffer layer and to contain the optical fiber within said ferrule. In some embodiments the ferrule includes an optical fiber situated within the bore.

An arm wrestling apparatus having an elevated frame with a first end and second end, a first side and a second side. Elbow pads are provided towards opposite corners of the apparatus and targets are provided on the frame diagonally across from each other on the corners not having the elbow pad structures thereon. This arrangement of the elbow pads and targets for winning cause the loser's arm to be bent in a natural direction, as contrasted with the direction of bending in conventional arm wrestling. Vertical and lateral adjusting mechanisms are provided for the elbow pads for accommodating the physical differences in dimensions for people's arms. Also, the positions of the elbow pads and targets can be shifted around the table to accommodate either a left or a right hand contest. Seats are provided for each contestant and mechanisms are provided for vertically adjusting the seats to accommodate various sizes of contestants for the purpose of equalizing the contest. Also, a mechanism is provided for adjusting the distance of the seat from each respective end of the table. An electrical circuit including numerous switches are provided to indicate the winner, and to detect cheating.
