    摘要: A fiber optic cable (10) includes a cable core (20) and a jacket section (30). Cable core (20) includes a central member (21), buffer tubes (23, 26), and optical fibers (22, 25) in respective buffer tubes. Jacket section (30) includes a tape layer (34) with a seam (35), and a seam guard (40) disposed over seam (35). Seam guard (40) is operative to perform dual functions, as the seam guard includes substrate (42) operative to prevent cable zippering, and a waterblocker (44) operative to inhibit the migration of moisture into cable core (20). FIGS. 1-3.

    摘要: A fiber optic cable (10) having a tube assembly (20) therein. Tube assembly (20) includes an optical fiber group (22) in a tube (21). Optical fiber group (22) comprises a medial optical fiber subgroup (23) and lateral optical fiber subgroups (24a, 24b;25a,25b;26a,26b) adjacent thereto. Subgroups (24a,24b;25a,25b;26a,26b) define a step-like profile for maximizing optical fiber packing density of tube assembly (20) and/or defining a high fiber count cable (10). In exemplary embodiments, a diagonal free space is defined as the tube inner diameter minus the diagonal length of the cross-section of the profile of the optical fiber ribbon stack, the diagonal free space being about 2 mm to about 5 mm. In a multi-tube embodiment, diagonal free space can be about 0.5 mm to about 2 mm. In other embodiments, corner fibers can have a delta optical attenuation of less than about 0.05 dB/Km for a wavelength of @1550 nm over a 100 meter length 40″ to 70″ drum at room temperature.

    摘要: Methods for heat treating glass sheets (13) are disclosed in which the sheets (13) are held in a vertical orientation in a treatment container (15) during the heat treatment. The container (15) includes a support system for the glass sheets (13) that comprises a bottom support (17), two side supports (19a, 19b), and a top support (21). The sheets (13) are slid into the container (15) without contact between their side edges (23a, 23b) and the side supports (19a, 19b). The top support (21) is then slid onto the tops of the sheets (13) without contacting the sheets' top edges (25). In certain embodiments, flushing air which has been HEPA filtered and pre-heated is passed through the container (15) during the heat treatment. Apparatus for practicing the methods of the invention are also disclosed.

    摘要: An optical tube assembly having at least one optical waveguide, at least one dry insert, and a tube. The at least one optical waveguide is disposed within the tube and generally surrounds the at least one optical waveguide. In one embodiment, the dry insert has a first layer comprising a felt having at least one type of non-continuous filament. The dry insert may also include a plurality of water-swellable filaments. In another embodiment, a dry insert has a first layer, a second layer, and a plurality of water-swellable filaments. The first and second layers are attached together at least along the longitudinal edges thereof, thereby forming at least one compartment between the first and second layers and the plurality of water-swellable filaments are generally disposed in the at least one compartment. The dry insert also is advantageous in tubeless cable designs.
