Abstract

Disclosed is a device which provides additional support to fiber optic cable, Fig. #1. This concept complements fiber optic cable by incorporating 3 key points: easy installation after terminating the cable ends, axial strain relief when anchored at both ends, and distributing stress created by sharp bends.

Backbone Support for the Fiber Cable

      Disclosed is a device which provides additional support to
fiber optic cable, Fig. #1.  This concept complements fiber optic
cable by incorporating 3 key points:  easy installation after
terminating the cable ends, axial strain relief when anchored at both
ends, and distributing stress created by sharp bends.

      An important feature of the backbone 1 is the shape of the
channels.  These channels are symmetrically positioned about the
center axis 2.  This gives the backbone the ability to flex in a
smooth and predictable manner.  The shape of the channel is also
designed to capture and protect the cable.  It has a tapered opening
3 with a cavity 4 beneath it.  Pushing a cable 5 against the tapered
face forces the opening to enlarge.  With enough pressure, the
opening will allow the cable to pass into the cavity. Applying
pressure like this along the axis of the cable, with a sliding
motion, the cable will slip into the channel with a zipper-like
action.  This gives the backbone support the feature of easy
installation.  Since the cable is not fed through the channel from
one end to the other, the support can be installed to cable with
terminated ends.

      When the ends of the backbone are anchored, it protects the
cable against axial forces.  Any force applied to the cable and
backbone will be transmitted to the backbone instead of the cable.
This transfer of force relieves the stress on the cable.
