摘要： A buffer tube for an optical fiber cable is made from a polypropylene-polyethylene copolymer resin having nucleating agents and filler materials disbursed therein. The nucleating agents and filler materials improve compression-tension resistance and thermal expansion properties of the polypropylene-polyethylene copolymer buffer tube (32). A non-armored cable structure incorporates the present invention and is generally indicated by the numeral (30). This structure includes a single, large, gel-filled buffer tube (32) made of a polypropylene-polyethylene copolymer at least incorporating a nucleating agent. The gel in the buffer tube is a thixotropic, water-blockable gel. The gel-filled buffer tube (32) contains a plurality of optical fibers (34). Radial strength yarns (36), made from either aramid, polyethylene, polyester, or fiberglass materials, are contra-helically stranded around the buffer tube (32) and impregnated with filling compounds such as a petroleum based hot melt filling compound. Two metallic or dielectric strength members (38) are located 180 degrees apart on the outside of the radial strength yarns (36). A high strength rip cord (40) is applied over the radial strength yarns (36) to aid in sheath removal. A medium-density polyethylene (MDPE) outer jacket (42) encapsulates the strength members (38) and radial strength yarns (36) to complete the structure. The MDPE of jacket (42) may be filled with carbon black powder.

摘要： An apparatus for applying gel to a plurality of optical fibers includes a housing having a cavity through which a plurality of separated optical fibers are fed. The gel is provided to the cavity from a gel reservoir via a pump that maintains the pressure and gel level to ensure that the optical fibers are coated with gel to eliminate air gaps and thus prevent sticking among the optical fibers.

摘要： In a fixed head burner (13), which may be used in the manufacture of optical fibers and preforms for optical fibers, a machined quartz nozzle (10) is provided for insertion into a threaded aperture (14) of the fixed burner head (13), the quartz nozzle (10) being sized to provide sufficient space between the quartz nozzle (10) and the burner head (12) to allow for relative differences in thermal expansion and contraction to prevent stress fracture of the quartz nozzle (10). A seating surfaces (85) is machined on the quartz nozzle (10) for contact with a machined surface (90) of the burner head (12), and the quartz nozzle is held in place by a spring (18) placed behind the quartz nozzle (10), the spring (18) being held in place by a threaded end cap (24). The secure retention of the quartz nozzle (10) within an aperture (14) in the burner head (12) is further aided by the pneumatic pressure of gases applied to a rear surface (20) of the quartz nozzle (10). During exposure to high temperatures, erosion of the quartz nozzle (10) may occur, however, the erosion by-products do not contaminate a preform or an optical fiber being heated by the burner head (12).
