摘要： A communication cable (20) includes a core (22) comprising a plurality of transmission media having a relatively supple layer (26) of a plastic material wrapped thereabout. Disposed about the layer of plastic material and in engagement therewith is a relatively rigid inner plastic jacket (28). Disposed about the inner jacket are additional components of a sheath system such as metallic shields and one or more additional plastic jackets. Interposed between the relatively supple layer of plastic material and the jacket is a water-blocking system which comprises two elongated strand materials (42, 44) such as yarns. The two elongated strand materials are wrapped helically about the layer of plastic material in opposite helical directions. The elongated strand materials are characterized by being yarn blends which comprise a portion of water-blocking filaments and a portion of relatively high strength filaments. The elongated strand materials are effective to intercept water which may travel along the cable between the relatively supple layer of plastic material and the jacket which is contiguous hereto. In addition, the relatively high tensile strength of the strand materials provides additional physical support to maintain the supple plastic material tightly around the transmission media.

摘要： A communication cable includes a core comprising at least one transmission medium and a sheath system which is disposed about the core. Means are disposed within the cable for preventing the longitudinal migration of water through the cable core, said means including both a hydrophilic material and a hydrophobic material in cooperative communication with each other. Specifically, a hydrophilic, water-absorptive material is supported by a yarn which is helically wrapped about various sections of the communication core. In a copper cable, the water-absorptive yarn may be wrapped about individual twisted pair conductors or a unit consisting of a plurality of twisted pair conductors or the cable core itself. In addition to the helically-wrapped, water-absorptive yarn, the cable of the present invention includes a hydrophobic, water-blocking material interdisposed to fill all voids and interstices within the communication core.

摘要： An animal-resistant optical fiber cable (20) includes a core (22) which comprises a transmission medium and a sheath system. The sheath system includes an outer jacket (65) and a dielectric armor (40) in the form of a shell. The shell comprises a plurality of longitudinally extending preformed segments (42--42) each being a composite comprising a substrate portion (50) and a layer (52) of a coating material which has a relatively high hardness disposed on an outer surface of the substrate portion. Each of the segments covers less than half of the periphery of the core and, in a preferred embodiment, eight segments are used. Further, the shell segments are stranded helically about the core with at least portions of longitudinal edge surfaces of adjacent segments being in engagement with each other. The shell segments not only provide rodent protection for the cable, but also they provide suitable tensile and compressive strength as well as suitable flexibility and cable bending performance. Further, because the cable in a preferred embodiment has an all-dielectric sheath system, it is inherently lighting, corrosion and EMP resistant.

摘要： An animal-resistant optical fiber cable (20) includes a core (22) which comprises a transmission medium and a sheath system. The sheath system includes an outer jacket (65) and a dielectric armor (40) in the form of a shell. The shell comprises a plurality of longitudinally extending preformed segments (42--42) each having an arcuately shaped cross section transverse to a longitudinal axis of the cable and each comprising glass fibers embedded in a matrix material. Each of the segments covers less than half of the periphery of the core and, in a preferred embodiment, eight segments are used. Further, the shell segments are stranded helically about the core with longitudinal edge surfaces of adjacent segments being in engagement with each other. The shell segments not only provide rodent protection for the cable, but also they provide suitable tensile and compressive strength.

摘要： An optical fiber cable particularly suited for use in building distribution systems includes a core which comprises a plurality of coated optical fibers (22--22) with each being enclosed in a plastic buffer (26). The optical fibers are individually or collectively enclosed in a fibrous strength member. Over the strength member in each of several embodiments is provided an outer jacket comprising a plastic material having excellent resistance to flame spread and smoke evolution. The plastic material comprising the jacket is disposed about the strength member and decoupled sufficiently therefrom to avoid the introduction of microbending stresses in the optical fiber. This may be accomplished by vacuum sizing the plastic material which has been tubed over an advancing optical fiber core as the plastic material is being drawn down onto the strength member.

摘要： A relatively small pair size cable (20) comprising at least one insulated conductor (22) is provided with a flame retardant, smoke suppressive non-metallic sheath system (30). The sheath system has a relatively low thermal conductivity and provides a predetermined delay prior to the thermal decomposition of the conductor insulation. It includes an inner layer (31) of an inorganic cellular material which has a relatively low air permeability and two tapes (41, 42) which are wrapped helically about the inner layer with overlapped sealed seams. Each tape comprises a flame retardant thermosetting material. In an alternative embodiment, the heat absorptivity of the sheath system is increased substantially to facilitate the sealing of the seams as the cable is moved along a manufacturing line. This may be accomplished by using an inorganic cellular material which has a relatively high absorptivity or by facing the inner layer or one of the tapes with a material which is heat absorptive.

摘要： A communications cable (20) comprising a core (22) of at least one transmission media and a plastic jacket (34) includes provisions for preventing the movement of water within the cable. The cable includes a strength system (32) including longitudinally extending fibrous strength members (33--33) having a relatively high modulus and having water blocking provisions. In one embodiment, each fibrous strength member is treated with a superabsorbent liquid material which when dry fills interstices and covers portions of the exterior thereof. In another embodiment, a filamentary strand material comprising a water swellable fibrous material is wrapped about each fibrous strength member.

摘要： A communications cable comprising a core of at least one transmission medium and a plastic jacket includes provisions for preventing the movement of water within the cable. An impregnated tape (35) is interposed between the core and the jacket and is wrapped about the core to form a longitudinal overlapped seam. The tape comprises a substrate tape (37) which is impregnated with a superabsorbent material which upon contact with water swells and inhibits the further movement of the water. The tape and its thickness are controlled so that the thickness is minimal while the tensile strength of the tape and its porosity prior to impregnation are optimized.
