Longitudinal stripping of optical cables mid-span is performed using specialized slitting tools that open the cable sheath without damaging the internal fibers.

Tools for Mid-Span Longitudinal Stripping

1. Mid-Span Slitters: Tools like the MSS100 allow longitudinal stripping of outdoor loose tube cables. The blade is pressed into the cable sheath and moved along the tube to open it on the upper and lower sides, providing access to the fibers inside .
2. Fiber Cable Sheath Slitters (SI-01): Designed for loose tube or ribbon-type cables, these tools adjust blade protrusion to accommodate various cable diameters (6–25mm) and are particularly convenient for mid-span branching .
3. Handheld Fiber Strippers: Smaller strippers, such as FOS03 or CFS-2, can remove outer jackets and coatings for smaller diameter fibers, often used for precise end or mid-span stripping .
4. LightOptics Jacket Slitters: Compact and lightweight, these tools slit PVC jackets into two halves efficiently, suitable for both field and plant applications .

Procedure for Mid-Span Stripping

1. Select the Correct Tool and Groove: Choose a slitter or stripper compatible with the cable diameter. For loose tube cables, select the proper groove to hold the tube securely .
2. Position the Cable: Place the cable in the tool opening and adjust rollers or clamps for a snug fit. Ensure the blade is set for longitudinal cutting rather than radial cuts .
3. Blade Adjustment: Adjust the blade depth to avoid cutting the internal fibers. Some tools allow blade revolvers or protrusion adjustments for precise control .
4. Strip the Sheath: Move the tool along the cable length to slit the sheath. For external strength member cables, allow the tool to follow the lay of the members, which may cause a slight spiral .
5. Access Fibers: Once the sheath is opened, carefully coil or store the buffer tubes in a slack storage area. Avoid cutting filler rods unless necessary .
6. Safety Considerations: Wear protective gloves and eyewear, as glass fibers are sharp and can pierce the skin. Collect any cleaved fibers with tape to prevent injury .

Tips for Effective Mid-Span Stripping

• Ensure the cable is supported and stable to prevent accidental fiber damage.
• Use tools with adjustable blades to accommodate different cable diameters.
• For high-fiber-count cables, coiling tubes in a splice closure reduces stress on fibers.
• Always follow manufacturer guidelines for the specific cable type and tool used. Using these specialized tools and procedures ensures efficient, safe, and precise mid-span longitudinal stripping of optical fiber cables without compromising fiber integrity.
