摘要： Optical cable with optical fibers and a water blocking element extending together along a passageway. The water blocking element swells upon contact with water so as to block the passageway against water migration. The water blocking element may be of filamentary structure, e.g. string or tape which acts as a carrier for water swellable particles, e.g. polyacrylate. The water blocking element may, however, be a filament of the swellable material which is spun with other filaments, e.g. polyester to form a string. The cable may be air pressurizable.

摘要： Optical fiber unit with optical fibers loosely contained within a flexible tube formed from two plastic strips which are bonded together along edge seams. The structure is completely flexible and the tube is compressible and deformable to assist in packing into channels in a cable while maximizing fiber density in the cable product.

摘要： Optical fiber units having an optical fiber housed within a flexible tube which in a normal axially unstressed condition is sinusoidal and approaches the fiber first on one side and then on the other. With this structure, upon tube shrinkage occurring, the amplitude increases so as to bend the fiber laterally at desired positions along the fiber length.

摘要： A fiber optic ribbon having a first subunit and a second subunit. The first and second subunits including a plurality of respective optical fibers being connected by respective primary matrices. The first and second subunits being generally aligned along a plane with a secondary matrix contacting portions of the first and second subunits. The secondary matrix having at least one end portion and at least one medial portion. The at least one medial portion and the at least one end portion of the secondary matrix are separated by a gap along at least a portion of the longitudinal axis, thereby defining a preferential tear portion. In other embodiments, the at least one medial portion is recessed relative to the at least one end portion.

摘要： In a fiber optic cable having a plurality of optical ribbons, identifying information about each optical ribbon is conveyed by a series of colored regions of different colors visible on an outer surface of the optical ribbon matrix covering. In preferred embodiments of the present invention, the colored regions are formed in such a way that they do not cause microbending or the like. Preferably, the colored regions are formed during the process of extruding the matrix covering over the fibers, by injecting colored material into the extrusion die.

摘要： A cable-stranding apparatus for performing SZ-stranding of strand elements about at least one core member is disclosed. A first stationary guide member individually guides the strand elements in a spaced apart configuration and centrally passes the at least one core member. At least one hollow-shaft motor is arranged downstream of the stationary guide member. A rotating guide member is disposed in the hollow shaft and rotates with the hollow shaft according to a rotation relationship. The rotation relationship controls the rotational speed and direction of the rotating guide member to SZ-strand the strand elements about the at least one core member to form an SZ-stranded assembly. Embodiments of cable-stranding apparatus having multiple hollow-shaft motors and respective multiple rotating guide members are also disclosed.
