    Abstract: An armored cable includes a core and an armor surrounding the core. The armor includes at least one armor access feature formed in the armor to weaken the armor at the access feature. A jacket surrounds the armor and the jacket includes a primary portion of a first extruded polymeric material and at least one discontinuity of a second extruded polymeric material in the primary portion, the discontinuity extending along a length of the cable, and the first material being different from the second material, wherein the bond between the discontinuity and the primary portion allows the jacket to be separated at the discontinuity to provide access to the core, and the at least one armor access feature and the at least one discontinuity are arranged proximate to each other to allow access to the core.

    Abstract: An crush resistant optical cable and/or crush resistant optical fiber buffer tube are provided. The cable generally includes a tube having at least one layer formed from a first material and an optical fiber located within a channel of the first tube. The buffer tube is configured to protect optical fibers from crush or impact events through a cushioning action. For example, the first material may be a polymer material having modulus of elasticity of less than 200 MPa, and the layer of the tube acts as a compliant cushioning layer at least partially contacting and surrounding an outer surface of the optical fiber when radially directed forces are applied to the outer surface of the tube.

    Abstract: A fiber optic cable includes a strength member, tubes coupled to the strength member, and optical fibers. The strength member provides tensile and anti-buckling strength. The tubes have a cavity into which the optical fibers are packed. The cable is stretchable in that the optical fibers experience less than 0.5 dB/km of increased average attenuation at 1310 nanometers wavelength when the cable experiences strain of up to 2x10 -3 .

    Abstract: An optical cable includes a core member and a plurality of strands wound around the core member in an SZ configuration, the SZ configuration having at least two reversal sections and a helical section extending along a longitudinal length between the at least two reversal sections. A helical lay length of the wound strands is variable along the longitudinal length of the helical section. A method of forming an optical cable includes providing a core member and surrounding the core member with a plurality of strands by winding the strands in an SZ configuration that includes a helical section extending longitudinally between at least two reversal sections.

    Abstract: A highly packed, low bend loss optical cable is provided. The cable includes an outer cable jacket and a plurality of buffer tubes surrounded by the cable jacket. Each buffer tube includes an inner surface defining a channel having a diameter, D1, and an outer surface facing an inner surface of the cable jacket. The cable includes a plural number, N, of optical fibers, located within the channel of each buffer tube and surrounded by the inner surface of the buffer tube. Each optical fiber has an outer diameter, D2. The N optical fibers are densely packed within each buffer tube such that a diameter ratio parameter, Ω, is defined as the ratio D1/D2, and is 2.25+0.143(N) ≤ Ω ≤ 1.14+0.313(N).

    Abstract: A fiber optic cable (110) includes a jacket (112), an element (114) of the cable (110) interior to the jacket (112), and first (120) and second (122) powders. The element (114) includes a first surface (124) and a second surface (126). The cable (110) further includes a third surface (128) interior to the jacket (112) and facing the first surface (124) at a first interface (132) and a fourth surface (130) interior to the jacket (112) and facing the second surface (126) at a second interface (134). At least one of the third (128) and fourth (130) surfaces is spaced apart from the jacket (112). The first powder (120) is integrated with at least one of the first and third surfaces (124, 128) at the first interface (132) and the second powder (122) integrated with at least one of the second and fourth surfaces (126, 130) at the second interface (134). The first interface (132) has greater coupling than the second interface (134) at least in part due to differences in the first and second powders.
