2. At one end of a shielded cable (item 2) measure a distance between "Window Min" to "Window
Max" (Table B-3) and cut a window (max size 0.35") in the jacket to expose the shield
(Figure B-2). Use caution when cutting the jacket to avoid damaging the individual braids of the
shield. When dealing with a densely populated connector with many cables, it may prove
beneficial to stagger the windows throughout the "Window Min" to "Window Max" range. If
staggering is not needed the "Ideal Window" length is recommended.
Suggested tools to accomplish the window cut:
•
Coaxial Cable Stripper
•
Thermal Stripper
•
Sharp Razor Blade
