摘要： An optical fiber cable including a central strength member, a first plurality of tight-buffered ribbon stacks, a binder film, and a cable sheath. The central strength member extends along a longitudinal axis of the optical fiber cable. The tight-buffered ribbon stacks are SZ-stranded around the central strength member. An interstitial space is provided between adjacent tight-buffered ribbon stacks. A binder film continuously and contiguously surrounds the first plurality of tight-buffered ribbon stacks along the longitudinal axis. The binder film includes first portions and at least one second portion. Each of the at least one second portion of the binder film extends into one of the interstitial spaces of the first plurality of tight-buffered ribbon stacks. The cable sheath continuously and contiguously surrounds the binder film along the longitudinal axis, and the cable sheath is coupled to the first portions of the binder film.

摘要： A strain sensing optical fiber cable is provided. The cable includes at least one optical fiber embedded in the cable jacket such that vibrations from the environment are transmitted into the cable jacket to the optical fiber. The cable is configured in a variety of ways, including through spatial arrangement of the sensing fibers, through acoustic impedance matched materials, through internal vibration reflecting structures, and/or through acoustic lens features to enhance sensitivity of the cable for strain/vibration detection/monitoring.

摘要： Provided are embodiments of an optical fiber cable. The optical fiber cable includes a cable jacket with an inner surface and an outer surface in which the inner surface defines a central cable bore and in which the outer surface defines an outermost surface of the optical fiber cable. The optical fiber cable includes from 48 to 864 optical fibers disposed within the central cable bore. Further, the outer surface of the cable jacket defines a cable diameter of at least 2 mm and up to 11 mm. The optical fiber cable has a fiber density of at least 7.5 optical fibers/mm2 based on a cross-sectional area of the optical fiber cable as measured from the outer surface of the cable jacket.

摘要： An optical fiber cable includes a jacket and a plurality of stranded core subunits, each core subunit comprising a flexible sheath and a plurality of ribbons arranged in a ribbon group, wherein each ribbon of the plurality of ribbons comprises a plurality of connected fibers such that 50-70% of the cross-sectional area inside the sheath is occupied by the connected fibers. The flexible sheath may be an extruded PVC material that conforms to the shape of the ribbon stack and keeps all of the ribbons acting as a unitary body during bending.

摘要： Provided are embodiments of an optical fiber cable. The optical fiber cable includes a cable jacket having an inner surface and an outer surface. The inner surface defines a central cable bore, and the outer surface defines an outermost surface of the optical fiber cable and a cable cross-sectional area (AC). At least one buffer tube is disposed within the central cable bore. Each buffer tube has an interior surface defining a buffer tube cross-sectional area (ATube, ID). A plurality of optical fibers (N) are disposed within the at least one buffer tube. Each optical fiber has a fiber diameter of 160 microns to 200 microns. The plurality of optical fibers have a total fiber area (AF). The buffer tube has a free space (1−AF/ATube, ID) of at least 37%, and the optical fiber cable has a fiber density (N/AC) of at least 3.25 fibers/mm2.
