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 least partially 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.
