Described are cable designs adapted for aerial installations wherein the cable comprises a bundle of multifiber tight buffer encasement units, with a conformal thin skin containment layer surrounding the bundle. The multifiber tight buffer encasement units have an acrylate compliant inner layer that protects the fiber and minimizes stress transfer to the fiber; and a hard, tough acrylate outer layer that provides crush resistance. The thin skin containment layer provides cable integrity with a minimum of added size and weight. The thin skin containment layer encasement is encased in an outer protective jacket.

Aerial optical fiber cables

Described are new cable designs for indoor installations wherein the cable comprises a dual-layer optical fiber buffer encasement of acrylate resin. The buffer encasement has an acrylate compliant inner layer that protects the fiber and minimizes stress transfer to the fiber; and a hard, tough acrylate outer layer that provides crush resistance. The dual-layer optical fiber buffer encasement is wrapped with reinforcing yarn and encased in an outer protective jacket. A dual jacket embodiment adapted for indoor/outdoor installations is also described.

Optical fiber cables

Polymer-coated transmission media having water-blocking material embedded in the outer surface of the transmission media prevents water penetration into the transmission media and reduces the overall diameter of a cable made from the transmission media by eliminating a water-blocking tape layer in the cable. The outer surface of the transmission media is a polymer whose outer surface is embedded with a water-blocking material. The water-blocking material is applied before the polymer is cured. The transmission media may be any known type of optical media, which guides a light within the optical media. In various embodiments, optical fibers, buffered optical fibers and fiber ribbons are used as the transmission media.

Optical fiber with water-blocking

Described are new cable designs for indoor installations wherein the cable comprises a dual-layer optical fiber buffer encasement of acrylate resin. The buffer encasement has an acrylate compliant inner layer that protects the fiber and minimizes stress transfer to the fiber; and a hard, tough acrylate outer layer that provides crush resistance. The dual-layer optical fiber buffer encasement is wrapped with reinforcing yarn and encased in an outer protective jacket.

A communication cable for being used in ducts or tubes comprising an outer jacket () which is formed with ribs () spaced around the periphery of the jacket and extending along the length of the cable. The new profiled cable has a lower index of friction when being installed in the ducts or tubes.

Communication cable and method of installing same

An aerial cable installation having an aerial cable suspended from a suspension point through a suspension device. This device has a clamp having two saddle members engaging the cable on diametrically opposite sides thereof and a plurality of nut and bolt assemblies extending through aligned holes in flanges of said saddle members for resiliently biasing the saddle members toward each other to clamp against the cable with a selected clamping force. To this end, each nut and bolt assembly includes a helical spring mounted on the bolt thereof between said flanges and the nut of the assembly and the springs are compressed a predetermined amout which is adjustable by tightening or loosening said assemblies.

Aerial cable installation and aerial cable suspension device therefor

An optical fiber cable for blown installation has a tubular central strength member about which tubes loosely housing optical fibers are stranded. The jacket is preferably formed from a high density polyethylene material and is extruded over the core on which rip cords are positioned. A water blocking compound is provided in each tube in any spaces therein which would otherwise be void. Also a water blocking material is provided between the sheath and the layer defined by the helically wound wrapping tape or binding yam in any spaces between the tubes which would otherwise be void.
