Abstract: An optical fiber cable comprising a polymeric jacket and at least one elongated buffer tube having a substantially circular cross-section and at least one optical fiber disposed within the at least one buffer tube. The optical fiber cable further comprises at least one dummy rod having a substantially non-circular cross-section, wherein the cross-sectional area of each dummy rod is at least 10% less than the cross-sectional area of the at least one elongated buffer tube along a majority of the length of the at least one dummy rod.

Abstract: An optical fiber cable includes at least one buffer tube that includes a plurality of water-blocking plugs and an optical fiber. The water-blocking plugs can be spaced along the buffer tubes, substantially filling the cross-sectional space within the buffer tube not already filled by the optical fiber. The water-blocking plugs can provide a stronger bond between the optical fibers and the inner tube. This is reflected by a high normalized pullout force for the optical fiber, such as, above 5.0 N/m. Yet, the resulting fiber optic cable does not suffer from problems associated with a higher pullout force, such as attenuation.

Abstract: A digital design system and method are provided for re-programmable hardware platforms, such as field programmable gate arrays (FPGAs) and other re-programmable system designs. The design system and method bridge the gap between what has previously been a development and prototyping platform used during the design phase of an electronic design system (EDS) project, and commercially viable re-programmable product platforms to replace non-programmable platforms, such as discrete processors and ASICs.

Abstract: An optical fiber cable has a core with a bore which loosely contains optical fibers and includes a single strength member unit preferably embedded in an outer jacket which surrounds the core. The single strength member unit allows for relative ease of bending of the cable in directions other than the bending directions in the plane of minimum bending energy for the cable, such as bending in the plane of maximum bending energy (MAX-BP) for the cable, and provides that the neutral surface associated with bending of the cable in the MAX-BP is outside the bore core and within the outer jacket. The single strength member unit, which is at least one strength member, furthermore provides tensile strength and antibuckling properties to the cable during storage and in expected installations, including an aerial installation. The outer jacket is releasably coupled to the core to provide ease of access to the optical fibers contained within the core bore.

Abstract: An optical fiber cable includes a central strength or structural member, buffer tubes of the desired flexibility are S-Z wound around the central member with a predetermined lay, preferably with alternating single turn S-Z lays and the buffer tubes loosely receive optical fiber ribbon stacks, the pitch of the twist being selected to provide a predetermined ratio of the pitch of the buffer tube lay. The wall thickness of the buffer tubes is selected to provide the desired buffer tube strength and crush resistance, and the diameters of the buffer tubes bores are selected in relation to the size of the optical fiber ribbon stacks so as to provide a predetermined clearance. The clearance C is between about 1 mm and about 2 mm with the relation: C=(TI2−WR2)½−HR Where TI is the inner diameter of the tube, WR is the width of said stack and HR is a thickness of the stack.
