20110293230 | OPTICAL CABLE WITH DRY CORE AND DRY BUFFER TUBES - An optical fiber cable includes at least one buffer tube that includes a plurality of water-blocking plugs and an optical fiber. The water-blocking plugs can be spaced along the buffer tubes, substantially filling the cross-sectional space within the buffer tube not already filled by the optical fiber. The water-blocking plugs can provide a stronger bond between the optical fibers and the inner tube. This is reflected by a high normalized pullout force for the optical fiber, such as, above 5.0 N/m. Yet, the resulting fiber optic cable does not suffer from problems associated with a higher pullout force, such as attenuation. | 12-01-2011 |

20090304338 | All-Dielectric Self-Supporting Cable Having High Fiber Count - An all-dielectric self-supporting optical fiber cable utilizes a single layer reverse oscillated lay (ROL) design and includes a fiber count of more than 288 fibers. By arranging buffer tubes in a single layer, the ADSS cable effectively isolates the tensile and thermo strain of the cable in central and outer strength members, thus preventing strain from aerial installation from impairing or otherwise inversely impacting the performance of the optical fibers. Moreover, fibers are loosely housed in bundles to permit fiber movement and further prevent strain on the fibers. | 12-10-2009 |

20110058779 | SPLITTABLE OPTICAL FIBER RIBBONS - A splittable optical fiber ribbon has a decreased propensity for fiber fallout along a longitudinal split. Fibers adjacent to a split location, called border fibers, have increased bond strength between their ink-coating and a surrounding matrix material. The bond strength is increased by first partially curing an ink that covers the border fibers, coating the partially-cured fibers with a matrix material, and then substantially fully curing the ink and the matrix material substantially simultaneously. The ribbon may include one or more grooves to enhance splitting the ribbon into subsets. | 03-10-2011 |
