    摘要: The present invention provides optical fiber communication cable assemblies useful for separating and conveying individual fibers from a multiple optical fiber cable to connectors in a protective manner. The optical fiber cable assembly is suitable for outdoor use and includes a (i) cable with multiple optical fibers; (ii) a furcation unit attached to the cable for directing individual optical fibers from the cable to furcation legs; and (iii) multiple furcation legs receiving at least one of the optical fibers. The furcation legs include (i) a buffer tube surrounding the optical fiber; (ii) strength members surrounding the buffer tube; and (iii) a jacket surrounding the strength members. The furcation legs typically exhibit a tensile rating of at least about 50 pounds (lbf), more typically 100 pounds (lbf) or more. Moreover, the furcation legs typically exhibit total shrinkage of less than about 2 percent when cycled from +23° C. to −40° C. to +70° C. to −40° C.

    摘要: Disclosed is an improved optical fiber that employs a novel coating system. When combined with a bend-insensitive glass fiber, the novel coating system according to the present invention yields an optical fiber having exceptionally low losses.The coating system features (i) a softer primary coating with excellent low-temperature characteristics to protect against microbending in any environment and in the toughest physical situations and, optionally, (ii) a colored secondary coating possessing enhanced color strength and vividness.The improved coating system provides optical fibers that are useful in reduced-size drop cables.

    摘要: Disclosed is a buffer tube that possesses a higher buffer-tube filling coefficient. Optical fibers enclosed within the buffer tube demonstrate improved attenuation performance when subjected to temperature variations between about −40° C. and 70° C. The buffer tube is suitable for deployments requiring mid-span access.

    摘要: Disclosed is a fiber-optic cable that possesses a high cable filling coefficient (and/or a high cable fiber density) yet ensures that its enclosed optical fibers demonstrate improved attenuation performance when subjected to temperature variations between about −40° C. and 70° C. The fiber-optic cable is suitable for efficient installation into ducts, such as via blowing.
