摘要： A fiber optic cable having strength assemblies (30) adjacent a tube having at least one optical fiber therein, at least one of the strength assemblies including a strength member for imparting crush resistance to the cable. The strength member is generally coupled to a first jacket, and may be surrounded by a single jacket, or by an armor tape and a second jacket. The strength member may be disposed in a recess of the tube. When crush loads are applied to the fiber optic cable, the stresses created in the cable are advantageously distributed by strength assemblies (30) whereby stress concentrations and undue deflection of the cable in response to the crush loads are avoided. The arrangement of the cable components and strength assemblies (30) inhibits slippage and/or warping of the components under stress, and thereby evenly distributes the stress for preventing crush induced attenuation in the optical fibers.

摘要： A fiber optic cable having strength assemblies (30) adjacent a tube for imparting crush resistance to the cable, at least one of the strength assemblies including a strength member in contact with a tube having at least one optical fiber therein. The strength member is coupled to a first jacket, and may be surrounded a single jacket, or by an armor tape and a second jacket. The strength member may be disposed in a recess of the tube. When crush loads are applied to the fiber optic cable, the stresses created in the cable are advantageously distributed by strength assemblies (30) whereby stress concentrations and undue deflection of the cable in response to the crush loads are avoided. Tight coupling and minimized gaps between the cable components in strength assemblies (30) inhibits slippage and/or warping of the components under stress, and thereby evenly distribute the stress for preventing crush induced attenuation in the optical fibers.

摘要： The present invention is an ultrasonic fluid densitometer that uses a material wedge having an acoustic impedance that is near the acoustic impedance of the fluid, specifically less than a factor of 11 greater than the acoustic impedance of the fluid. The invention also includes a wedge having at least two transducers for transmitting and receiving ultrasonic signals internally reflected within the material wedge. Density of a fluid is determined by immersing the wedge into the fluid and measuring reflection of ultrasound at the wedge-fluid interface.

摘要： An armored cable having a polymer covering where the bond between the armor and the covering is controlled by introducing particulate matter at the interface of the armor and covering. A filler material is applied to the exterior surfaces of the cable strength elements in order to inhibit the formation of voids in the polymer covering that would otherwise promote water migration along the cable.

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： A fiber optic cable (10) having a cable core (20) includes fiber optic cable components in the form of buffer tubes (23), a binder (26), and strength members (31). Cable core (20) includes a series of stripes (38) that comprise a mixture of adhesive and water absorbent substances. The water absorbent substance of stripes (38) is operative to swell and thereby block the flow of water in cable (10). Stripes (38) are made by the sequential coating of the adhesive and the water absorbent substances onto the cable whereby the water absorbent substance is propelled into interstices between the cable components. FIGS. 2 and 4.

摘要： A fiber optic cable is that includes at least one optical fiber and a protective layer generally disposed about the optical fiber. A cable jacket surrounds an outer surface of the protective layer, and a control layer is interposed between a portion of the protective layer and a portion of the cable jacket. The control layer includes one or more apertures extending therethrough, thereby creating a predetermined bond between the protective layer and the cable jacket. By way of example, the protective layer is an armor layer, buffer tube, or other suitable cable component where a predetermined bond to the cable jacket is desired so the craft can easily remove a portion of the cable jacket. The plurality of apertures can have any suitable size, shape, and/or arrangement for influencing the desired bond strength. A method of manufacturing the fiber optic cable is also disclosed.

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 an exemplary embodiment, fiber optic cable (10) can include strength assemblies (30) on opposing sides of tube assembly (20) for defining a preferential bend plane in fiber optic cable (10).
