Abstract: The present disclosure provides an armored cable (100) comprising a plurality of sub units (104), the sub units (104) comprising a plurality of optical fibers (106). The sub units (104) are enclosed in a thin protective layer (110), which is placed within an armor layer (108). An outer cable jacket (112) surrounds the armor layer (108), which optionally comprises at least a strength member (114).

Abstract: The present disclosure provides an armored cable (100) comprising a central core (102) comprising a plurality of intermittently bonded ribbon (IBR) bundles (104) enclosed in a protective layer (106), which is placed within an armor layer (108). An outer cable jacket (110) surrounds the armor layer (108), which optionally comprises at least a strength member (114).

Abstract: The present disclosure provides an armored cable (100, 200) including a plurality of optical fibers (106) arranged in a plurality of IBRs, which can be bundled or unbundled. The IBRs are enclosed by a first layer of thin polymer sheath (102, 202). The first layer (102, 202) is further enclosed in a second layer (108, 208), which is placed within an armor layer (110, 210). An outer cable jacket (112, 212) surrounds the armor layer (110, 210), which optionally comprises at least a reinforcing member (114, 214).

Abstract: The present disclosure provides an optical fiber ribbon (10) comprising a plurality of optical fibers (11) with coating of superabsorbent material (C). The coating (C) is applied selectively on bonded regions (13) or unbonded regions (14) of the ribbon (10). The ribbon (10) provides for reduced diameter, higher packing density, and reduced micro-bending losses. Optical fiber cable (20) comprising optical fiber ribbon (10) is also provided in the present disclosure.

Abstract: An optical fiber cable [100] is disclosed that is capable of aerial suspension. The optical fiber cable [100] comprises at least one substantially round, flexible outer sheath [102]; at least one easily peelable color coded sleeves [106] enclosing plurality of fibers [104]; and at least one strength member [108] suspended linear to an axis of the fiber optical cable [100] and surrounded with an anti-corrosion coating, wherein the optical fiber cable [100] has breaking strength between 1300 and 2000 N.

Abstract: The specification describes an optical fiber drop cable with a flat configuration and having two side-by-side subunits. One of the subunits contains a cable strength member, e.g. a steel wire or stranded wire. The other subunit is an optical fiber subunit, which contains the optical fiber(s), and also contains one or more additional strength members. In a preferred embodiment, the cable is dry, and has conformal encasements that couple the optical fiber(s) to the outer cable sheath.

Abstract: The specification describes optical fiber cables designed for microduct installations. The microduct cables are coated with a sheath having particulates added to modify the drag of the outer surface of the cable to air, and thereby facilitate air blown installation. The particulates are nanoclay, silica, alumina, or other suitable solid particles of less than 5 microns. The coating comprises a prepolymer containing the filler, and is UV cured.

Abstract: The specification describes an improved optical fiber cable wherein the cable cross section is round and contains a plurality of bundled optical fibers. The bundle may comprise randomly spaced fibers or fibers aligned in a ribbon configuration. The bundle is encased in a polymer encasement that couples mechanically to each optical fiber. Preferably, the fibers are spaced from the nearest neighbor to improve coupling. In some embodiments the encasement is relatively hard, and is deliberately made to adhere to the optical fiber bundle. Consequently the encasement medium functions as an effective stress translating medium that deliberately translates stresses on the cable to the optical fibers. The cable construction of the invention is essentially void free, and provides a dry cable with water blocking capability.

Abstract: A pneumatic horn comprises a housing portion, a base portion connected with the latter, a sound horn, which is held in an opening of the housing portion, and a diaphragm which is fixed between the housing portion and the base portion and rests against an inner pipe connection piece. The housing portion and the base portion each comprise a ring. Each ring is connected with a sheet metal jacket or a sheet metal base, respectively, so as to be fixed against rotation relative to it. The housing portion and the base portion carry diaphragm holding surfaces which securely grip the diaphragm all around in a uniform manner when the housing and base portions are screwed together.
