Disclosed is a method and apparatus for protecting optical ribbon fiber assemblies from damage during applied uses. The disclosure addresses protecting un-jacketed fiber optic ribbons from damage when they are inserted into small spaces and enclosures. There are also applications where optical ribbon will be clamped in organizers. This will require some protection on the ribbons to prevent glass fracture.

Method Protecting Unprotected Optical Ribbon Fiber


This invention uses a slotted piece of PVC with imbedded kevlar fibers to protect the fibers. The advantages of using this method is the slotted PVC can be customized to the required lengths and cable OD's. It also allows for easier routing of the ribbon around tight bends while affording selective protection where required.

This invention uses the design/method:
§ Slotted Mechanical Device (Figure 1)
§ Contains imbedded kevlar fibers (Figure 2)
§ Adaptable to different cable diameters
§ May be spiral cut for ease of application
§ May be pre-cut pieces (1-2 inches) for selective protection
