Abstract

Abstract An optical fiber ribbon composite, each ribbon joined to adjacent ribbon by a flexible web member, the web member having sufficient length so that the optical fiber ribbons can be moved to positions where the plane delimited by the optical fibers of any given ribbon is spaced apart from, but generally parallel with the plane(s) delimited by the optical fibers of the other ribbons of the composite. One or more of the composites is used as a component of a fiber optic cable.
