    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.

    摘要： A mark sensor and methods for detecting a core mark disposed on a fiber optic cable core having a core receiving area for receiving the fiber optic cable core. The mark sensor includes emitter/receiver sensor devices that can be disposed about the core receiving area for observing a portion of the core for detecting the core mark. The mark sensor can include a sensor positioning system for moving the sensors relative to the core receiving area. The sensor positioning system is operative to move the sensors upon insertion of the cable core in the core receiving area. The sensor positioning system can include a linkage to another mark sensor for transmitting sensor motion to the other mark sensor. Alternatively, the mark sensor can include stationary sensors that sweep the core with radiation, for example, a bar code reader. Methods for using the foregoing sensors can result in the direct or offset marking of reverse oscillation of lay areas in a fiber optic cable.

    摘要： Fiber optic drop cables are disclosed that are suitable for automated preconnectorization. In one embodiment, an optical waveguide is disposed in a buffer tube that has two strength components disposed on opposite sides thereof and a plurality of strength members. The plurality of strength members are disposed at a plurality respective interstices located between the buffer tube and the two strength components and shaped into a plurality of substantially triangular shapes for improving the balancing of the residual stresses in the fiber optic cable caused by the shrinkage of a cable jacket during cooling. In another embodiment, a fiber optic cable includes a tonable lobe connected by a web that is frangible and the web includes predetermined ratios for easily and reliable separation of the tonable lobe.

    摘要： A buffered optical fiber includes at least one optical fiber and a buffer layer. In one embodiment, the buffer layer generally surrounds the optical fiber and has a non-round cross-section that includes a plurality of wings that are an integrally formed by the buffer layer. Additionally, the buffered optical fiber may form a portion of a fiber optic cable that allows a relatively small bend radius while maintaining optical performance. Optionally, the optical fiber may be a bend resistant optical fiber for preserving optical performance. Additionally, other fiber optic cables that allow relatively small bend radii are also disclosed.

    摘要： Fiber optic cables are disclosed that allow a relatively small bend radius and/or may kink while still preserving optical performance. In one embodiment, the fiber optic cable includes at least one optical fiber, a first strength member, a second strength member, a core material, and a cable jacket. The core material generally surrounds the optical fiber, the first strength member, and the second strength member and the core material is deformable for cushioning the optical fiber. The cable jacket generally surrounds the core material and allows a bending radius of about 10 millimeters or less while maintaining a suitable level of optical performance.

    摘要： A fiber optic cable is provided that includes a plurality of lengthwise extending, non-jacketed bundles of optical fibers and a cable jacket surrounding the bundles of optical fibers. Each bundle of optical fibers may include a binder, such as a binder thread, for maintaining the integrity of the bundle. The binder may include, for example, a binder thread formed of an air entangled, textured, continuous multi-filament thread. The fiber optic cable may also include a separation element for preventing adhesion between the bundles of optical fibers and the cable jacket without having to separately jacket each bundle of optical fibers.
