Outer jacket. This flexible insulating material is also called a sheath, typically a soft plastic material.
- On single-fiber cables (as diagramed above), this jacket OD is usually 2-3mm in diameter, and can be stripped using common wire-strippers of the appropriate gauge.
- When selecting the proper wire-stripper gauge, it is important to consider the layer underneath (in this case, the Aramid Yarn): you do not want to damage any of the yarn fibers, as they play an important role in connector tensile strength.
- After removing the Jacket, observe the Aramid Yarn fibers at the strip point. Are they damaged? Are any of them cut? Even a small % of cut fibers will significantly reduce finished-product pull-strength. If you see cut yarn fibers, likely you need to use a larger gauge wire stripper.
- The edge of the jacket, after stripping, should be cut clean—not torn or ripped.
