Abstract: A dust cap assembly includes a sleeve and a sealant that seals an end face portion of a fiber optic ferrule from contaminants and, upon removal, provides remedial cleaning of any foreign matter present on the ferrule when the dust cap assembly was initially installed along with methods of making the same. The sleeve of the dust cap assembly has a through bore and a distal end for receiving the sealant. Further, the sealant may optionally have advantageous mechanical and optical properties such that the dust cap assembly may function as a terminator for testing.

Abstract: Fiber optic connectors having an optical fiber stub that is fusion-spliced for optical connection and related tools for the fiber optic connectors are disclosed. Specifically, the connector assembly for fusion-splicing includes a fiber optic connector having an optic fiber stub and a boot attachable to the fiber optic connector. The boot is configured to transfer the majority of the axial force from the fiber optic cable to the fiber optic connector. Specifically, a splice housing for housing the fusion splice is configured for attachment to an end of the boot for transferring forces from the fiber optic cable to the boot. Consequently, the boot preferably has an extensibility of less than about 2 millimeters under an axial load of about fifteen pounds to inhibit excess forces from acting on the optical fiber stub.

Abstract: 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.

Abstract: A dust cap assembly comprising a sleeve and a sealant that seals a fiber optic ferrule from contaminants and, upon removal, provides remedial cleaning of any foreign matter present on the ferrule when the dust cap assembly was initially installed. Further, the sealant has advantageous mechanical and optical properties such that the interaction of the sealant, the sleeve and the fiber optic ferrule defines a convex shape. The dust cap assembly may therefore function as a terminator that reduces back reflection during testing.
