Patent ID: 8401353

Claim:
A cable assembly for transitioning individual optical fibers from a multiple optical fiber cable to connectors, comprising: a furcation unit for attachment to an end of a fiber optic cable comprising multiple optical fibers, wherein said furcation unit is structured to direct individual optical fibers from a cable to corresponding furcation legs; and multiple furcation legs, each having an end attached to said furcation unit, capable of receiving at least one optical fiber, each of said furcation legs comprising (i) a buffer tube (ii) strength members surrounding said buffer tube, and (iii) a jacket surrounding said strength members, wherein said buffer tube and/or said jacket of at least one of said furcation legs comprises a nucleated polypropylene-polyethylene copolymer exhibiting a post-extrusion shrinkage of less than about 0.5 percent, and wherein each of said furcation legs exhibits total shrinkage of less than about 2 percent when cycled from +23° C. to −40° C. to +70° C. to −40° C., and wherein at least one of said furcation legs has a tensile rating of at least about 50 pounds (lb f ).
