Abstract: A mesh (36) is placed around a bundle (32) of fused glass fibers. The bundle is then immersed in a leaching bath (44). The ends of the bundle are protected from the bath fluid by furrules (34). Some of the glass of the bundle is leached out, so as to provide a flexible fiber bundle.

Abstract: A method of mounting electro-optical devices on an optical element using an auxiliary substrate is provided herein. Electro-optical fiber optic assemblies are also described herein.

Abstract: An assembly for mounting at least one optical fiber including a mounting frame defining a passageway therethrough. A fiber assembly plate generally defines a plane generally perpendicular to an axis of the at least one optical fiber and has a perimeter. The fiber assembly plate receives the at least one optical fiber. A mounting mechanism is disposed at a fixed location on the mounting frame and supports the fiber assembly plate over the at least one passageway. The mounting mechanism allows generally planar thermal expansion and/or contraction of the fiber assembly plate. A method of positioning at least one optical fiber in optical communication with an optical component using an athermal mount is also disclosed herein.

Abstract: A method to skew or deskew a plurality of optical channels in a multichannel optical cable which includes the steps of determining an optical pulse transmission time in at least a first channel and a second channel of the multichannel optical cable. A relative pulse delay between the first channel and the second channel of the multi-channel optical cable is calculated. Delay optics with the appropriate relative pulse delay are serially optically connected to at least one of the channels to one of skew or deskew the first channel relative to the second channel.

Abstract: A system for positioning at least one optical fiber. The system includes a plate having a major surface defining a hole adapted to receive an optical fiber. A spring is located on the plate and is located at least partially within the hole to position the optical fiber therein and/or additional plates are used to position the optical fiber.

Abstract: A fiber optic cable includes a core and a surrounding protective layer. The core includes an inner tube having one or more optical fibers contained therein, and the surrounding protective layer includes an outer tube received over the inner tube, and a layer of buffer material positioned between the outer tube and the inner tube. The buffer material maintains the inner tube generally centrally located within the outer tube and providing a mechanical link between the inner tube and the outer tube to prevent relative movement therebetween. The inner tube may be coated with a low hydrogen permeability material to minimize the entrance of hydrogen into the inner tube. The low hydrogen permeability material may be coated with a protective layer of hard, scratch resistant material to protect the integrity of the low hydrogen permeability material.

Abstract: A multi-fiber in-line attenuator module configured for insertion in the fiber optic pathway of an optoelectronic network to provide a predetermined value of attenuation for all propagating modes in the pathway includes first and second multi-channel interface members each having a mating face, an interconnect face, and alignment holes and n-optical channels formed therethrough, a multi-fiber ribbon cable terminating in the interconnect face of each multi-channel interface member with the optical fibers thereof disposed in the n-optical channels, alignment pins disposed in the alignment holes of the first and second multi-channel interface members so that the n-optical channels of the first and second multi-channel interface members are optically aligned, a mating clip for retaining the first and second multi-channel interface members in mated combination, and an NDF (neutral density filter) film adhered to at least one of the mating faces of the first and second the multi-channel interface members, the adhere

Abstract: A fiber optic transmission cable fiber protector includes a splice tube positioned over the ends of a pair of fiber optic cables having an outer capillary tube containing at least one optical fiber within an inner capillary tube. The optical fiber protector includes a pair of optical fiber strain relief mechanism positioned near the ends of the optical fibers; the strain relief mechanisms are captured within a heat sink tube that is inserted into each end of the outer capillary tubes. The splice tube is welded to the outer capillary tubes. Heat generated by the welding process dissipated by the heat sink and gases generated during the welding process are vented through a hole in the outer capillary tube into the optical fiber splice area. In an alternate embodiment a weld coupling is welded to each end of the splice tube and is further welded to the outer capillary tubes. A sealing mechanism is positioned on the inner capillary tubes within the outer capillary tubes forming a seal therebetween.
