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.

Cable-stranding methods for performing SZ-stranding of strand elements about at least one core member are disclosed. One method includes passing initially spaced apart strand elements through peripheral guide holes and passing at least one core member through a generally central location of at least one guide member. The method also includes actuating a controller that controls the rotation of the at least one guide member and rotating the at least one guide member to form the SZ-stranded assembly.

A cable-stranding apparatus includes a stationary guide, a motor, a driven guide, and a controller electrically coupled to the motor. The stationary guide is configured to guide strand elements in a spaced-apart configuration and to pass a core member. The motor is operatively associated with a guide driver. The driven guide is disposed at least partially within the guide driver so as to rotate therewith. The driven guide is configured to receive the strand elements from the stationary guide, individually guide the strand elements received from the stationary guide, and to further pass the core member. The controller is electrically coupled to the motor and configured to control the rotational speed and direction of the motor.

摘要:
A fiber optic ribbon having a predetermined separation sequence including a first subunit having a plurality of optical fibers arranged in a generally planar configuration being connected by a first primary matrix. The first subunit being a portion of a first ribbon-unit. A second subunit having a plurality of optical fibers arranged in a generally planar configuration being connected by a second primary matrix. The second subunit being a portion of a second ribbon-unit that includes a plurality of subunits. A secondary matrix connects the first ribbon-unit and the second ribbon-unit. The secondary matrix has a preferential tear portion disposed adjacent to a ribbon-unit interface defined between the first ribbon-unit and the second ribbon-unit.

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 plurality of fiber optic cables are manufactured as an assembly of fiber optic cables that are later separated into independent fiber optic cables. A method of manufacturing the fiber optic cable assembly is also described. A jacketing cover is extruded over components of the fiber optic cables with a portion connecting the fiber optic cables, and the fiber optic cables can separated from each other by tearing, cutting, or removing a filling element between the fiber optic cables.
