  • Publication number: 20040223709
    Abstract: 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.

  • Publication number: 20040170364
    Abstract: 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.

  • Patent number: 6731844
    Abstract: 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.
