Embodiment Construction

[0020] figure 1 is the cross-sectional profile of an optical fiber distribution or breakout cable 10 according to the invention. As described below, the cable 10 is particularly suitable for routing along building corridors to serve multiple dwelling units or premises in a multi-dwelling unit (MDU) building without negative visual or aesthetic impact on nearby observers. influences. Those skilled in the art may find the cable 10 to be particularly useful for other applications as well.

[0021] In the disclosed embodiment, the cable 10 contains twelve coated optical fibers 12a, 12b, . Optical fibers may include, for example, one or more of the aforementioned Fiber, each The fibers all have a 125 micron diameter cladding and are intended for indoor and MDU building applications. The cladding is coated with a thermosetting polymer coating 20 made of an ultraviolet (UV) curable acrylate oligomer having an outer diameter (O.D.) of approximately 240 microns, and is typical...

Abstract

An optical fiber distribution or breakout cable for serving multiple customer premises in a multi-dwelling unit (MDU) building. The cable contains a number of bend insensitive fibers each having a different colored coating for identification. A jacket of a flame-retardant polymer compound is extruded to surround the fibers. The jacket is sufficiently opaque to hide the color coated fibers at leastpartially from view, and the outer diameter of the jacket is not more than about 3.5 mm. A procedure for installing the cable through a hallway of a MDU building so as to lessen any negative visual impact of the installation on observers nearby is also disclosed.

Description

[0001] Cross References to Related Applications [0002] This application claims priority under 35 U.S.C. §119(e) to U.S. Provisional Patent Application No. 62 / 145,010, filed April 9, 2015, entitled "Low VisualImpact Multi-Fiber Microcord," the entire contents of which Incorporated herein by reference. technical field [0003] The present invention relates to communication cables, in particular fiber optic distribution cables for serving multiple different customer dwelling units or premises in a multi-dwelling unit (MDU) building. Background technique [0004] More and more fiber optic cables are installed each year to meet the demand for fiber-to-the-home (FTTH) communication services from customers occupying living units or other premises in multi-dwelling unit (MDU) buildings. These services usually include things like television, telephone and Internet access. Recent advances in fiber and cable technology have facilitated such installations, particularly ultra-bend-in...
