    摘要: A fiber optic cable includes a buffer tube, a plurality of ribbons of optical fibers extending through the buffer tube and a grease layer disposed between at least one pair of adjacent ribbons. The grease layer includes a base component and a plurality of agglomerates formed filler particles, such as silica particles. The major dimension of the majority of the agglomerates is advantageously less than 100 microns in order to reduce microbending of the optical fibers and the resulting attenuation of the signals propagating along the optical fibers. The fiber optic cable can also include a filling compound that is disposed within the buffer tube and surrounds the optical fibers and that is also formed of a base component and a plurality of agglomerates, the majority of which similarly have a major dimension of less than 100 microns.

    摘要: Disclosed are fiber optic assemblies having at least one optical fiber disposed within a tube and/or cavity along with a powder or powder blend that is at least partially mechanically attached thereto. In one embodiment, the powder or powder blend includes a water-swellable component that is mechanically attached to about 30 percent or less of the surface area of the tube wall while still effectively blocking the migration of water along the tube. Other embodiments may have the powder or power blend mechanically attached to the tube, cavity, or the like at relatively high percentage levels of the total powder or powder blend within the assembly, thereby inhibiting unintentional migration along the tube, cavity, or the like. Other embodiments may use powder or powder blends that may or may not include a water-swellable powder to provide other desired characteristics.

    摘要: Disclosed are fiber optic assemblies having at least one optical fiber and a water-swellable powder within a tube and/or cavity and methods for making the same. Fiber optic assemblies of the present invention use relatively low-levels of water-swellable powder while still effectively blocking the migration of tap water and/or saline solutions of 3% by weight along the tube and/or cavity. Furthermore, cleaning of the optical fibers is not necessary before connectorization like with conventional fiber optic cables that use a gel or grease. Generally speaking, at least some of the water-swellable powder is transferred to the inside surface of the tube, cavity, optical fiber or the like; rather, than being a loose powder that is able to migrate within the tube or cavity. Moreover, the existence of water-swellable powder within the fiber optic assembly or cable is nearly transparent to the craft since relatively low-levels are possible.
