Abstract
A ribbon drop cable is provided. The ribbon drop cable includes a ribbon band of a plurality of communication medium. The ribbon band having a top flattened portion, a bottom flattened portion, a first side and a second side. At least one dielectric strength rod is disposed proximal to either the first side or second side of the ribbon band. The ribbon drop cable further includes a sheath which surrounds the ribbon band and the strength elements. The sheath is configured to hold the strength elements and the ribbon band in alignment.

16. A ribbon drop cable comprising:
-
(a) a ribbon band of a plurality of optical fibers, the ribbon band having a top flattened portion, a bottom flattened portion, a first side and a second side; (b) two strength elements with one strength element being disposed proximal to the first side and the other strength element being disposed proximal to the second side of the ribbon band; (c) a sheath which surrounds the ribbon band and the strength elements, the sheath being configured to hold the strength elements and the ribbon band in alignment along a cross-sectional long axis of the ribbon drop cable; and (d) at least one water-blocking yarn disposed adjacent the sheath. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24)

25. A ribbon drop cable comprising:
-
(a) a ribbon band of a plurality of optical fibers, the ribbon band having a top flattened portion, a bottom flattened portion, a first side and a second side; (b) two strength elements with one strength element being disposed proximal to the first side and the other strength element being disposed proximal to the second side of the ribbon band; (c) a sheath which surrounds the ribbon band and the strength elements, the sheath being configured to hold the strength elements and the ribbon band in alignment along a cross-sectional long axis of the ribbon drop cable such that the ribbon band is centered between the strength elements within the sheath with a portion of each strength element having a height that extends above the ribbon band and a portion of each strength element having a height that extends below the ribbon band in the short axial directions of the ribbon drop cable; (d) the sheath forming respective webs between the two strength elements and the ribbon band, the webs having a thickness between each strength element and the ribbon band that increases ease of removal of the strength elements or the ribbon band from the ribbon drop cable, while preventing breakage of the webs during handling of the drop cable; and (e) at least one water-blocking yarn, the at least one water-blocking yarn being disposed within the sheath adjacent the ribbon band.
