• The rear end of the outer ferrule does not extend farther than the rear end of the inner
ferrule
• The rear end of the outer ferrule is a maximum of 0.06 inch from the rear end of the
inner ferrule.
(h) Crimp the ferrules.
(12) Do Step 10.F.(11) again to assemble the other end of the shield splice.
Make sure that the shield sleeve material is pulled tightly before the ferrules are crimped.
(13) Remove the shield and the shield sleeve material that extend farther than the rear end of the
inner ferrule on each end of the shield splice.
(14) Tightly wind a layer of the tape on the splice assembly.
Make sure that the layer of tape:
