Optical fiber cable construction

摘要

This optical fiber cable has the optical fibers adhered to a support. An assembly including the fibers and the support is carried by a core element having a helical channel in which the fiber assembly is located and free to adjust itself to accommodate bending of the cable without subjecting the optical fibers to pressure or to bends that are excessively sharp. The construction also avoids pressure on the optical fibers from binders, core tapes, or the cable sheath when the cable is bent. It also avoids micro-bending losses. Locating of the optical fibers closer to the cable axis further decreases bending losses.
