摘要： A tube assembly of the present invention has at least one subunit with at least one dry insert generally surrounding the subunit which may be disposed within a tube, thereby forming a tube assembly. The subunit includes a fiber optic ribbon and a sheath, wherein the sheath is tight-buffered about the fiber optic ribbon, thereby inhibiting buckling of the ribbon during temperature variations. Additionally, the tube assembly can be a portion of a fiber optic cable having a sheath that may include a plurality of strength members and a cable jacket. In other embodiments, the subunits and dry insert are disposed within a cavity, thereby forming a tubeless cable. Additionally, subunits may include a marking indicia for denoting the security level.

摘要： A fiber optic cable having both water blocking and flame retardant properties that is particularly useful for indoor or indoor/outdoor applications. In one embodiment, the fiber optic cable includes at least one buffer tube, at least one optical fiber disposed within the buffer tube, a composite tape surrounding the buffer tube that comprises a layer formed of an inherently flame retardant material and at least one coating a water swellable material, and a jacket surrounding the composite tape. The fiber optic cable can also include a water blocking element disposed within the buffer tube. The water swellable coatings of the composite tape and the water blocking element within the buffer tube therefore inhibit water migration along the length of the cable, while the flame retardant layer of the composite tape provides fire resistance. In another aspect, a dry fiber optic cable that includes a buffer tube comprised of an inherently flame retardant material, at least one optical fiber disposed within the buffer tube, a first tape comprised of a water swellable material that at least partially surrounds the at least one optical fiber, at least one roving extending lengthwise along the buffer tube and having a coating comprised of a water swellable material, and a jacket surrounding the buffer tube and the at least one roving. As such, the buffer tube provides flame retardant properties, while the first tape and the water swellable coating of the at least one roving inhibit water migration along the length of the cable.

摘要： A composite cable for use in indoor or indoor/outdoor applications having a fiber optic core section includes at least one optical fiber. The composite cable includes a conductor and water blocking section, the conductor and water blocking section having a set of conductors providing mechanical strength and flame inhibiting characteristics to the composite cable. At least one interstice of the composite cable includes a water blocking member therein. An armor layer surrounds the conductor and water blocking section, and the armor layer is surrounded by a cable jacket with an interfacial zone defined therebetween. The interfacial zone includes a controlled bond layer so that during flame tests, as the jacket burns and forms a char barrier around the tape layer, the controlled bond layer supports the char barrier relative to the armor tape, thereby protecting the tape from flames and inhibiting the propagation of flame along the cable.

摘要： One embodiment is a fiber optic cable including at least one subunit, a tube, a plurality of strength members, and a cable jacket. The subunit includes a fiber optic ribbon and a sheath, wherein the sheath is tight-buffered about the fiber optic ribbon, thereby inhibiting buckling of the ribbon during temperature variations. The tube houses at least a portion of the at least one subunit to form a tube assembly. The plurality of strength members are disposed radially outward of the tube and are surrounded by the cable jacket. Other embodiments include a plurality of subunits in a stack with each subunit having a sheath for security purposes. Additionally, a tube assembly can have a fiber optic packing density of about 0.05 or greater.

摘要： A spirally wound electrode assembly for use in electrochemical cells has an outer anode layer and an electrically insulating and ionically impermeable overwrap film disposed about the assembly. The outer anode layer has a tab located thereon. The overwrap film is inserted into the assembly between the end of the cathode layer and one of the anode layers. Upon forced discharge of the cell, the portion of the anode with the tab is disconnected in a fuse-like manner from the remainder of the anode, and the circuit is thereby broken.
