3.3.2 Shield Termination Technique – Method A.1 (Standard)

Figure 3-3.
1. The appropriate number of Backshells will be included in the particular LRU connector kit.

2. At one end of a shielded cable (item 2, Figure 3-1 or Figure 3-2 ) measure a distance between
“Window Min” to “Window Max” (Table 3-6) and cut a window (max size 0.35”) in the jacket to
expose the shield (item 4, Figure 3-3). 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
