Furcation tubing is made of glass-filled Teflon (PTFE) that provides reduced longitudinal shrinkage and increased tensile bond strength in the standard colors utilized for fiber identification. The furcation tubing experiences no more longitudinal shrinkage than furcation tubing made of polyvinylidene fluoride (PVDF) and has a tensile bond strength no less than furcation tubing made of clear, etched Teflon (PTFE). A fanout furcation kit prevents movement of the separated optical fibers in a funnel area of a lower furcation body. The funnel area is bathtub shaped with an increasing depth in the direction of an insert block having at least two rows of passageways in a staggered array. Guide walls defining the funnel area form a seal with an upper furcation body. Use of the furcation tubing and fanout furcation kit significantly reduces unacceptable attenuation and micro-damage to optical fibers deployed in an outdoor fiber optic network.
