STRIP CABLE
Strip cable jacket approximately 6” (152 mm) from end and place Crimp Support over fiber and Kevlar
so that it stops at the end of the jacket. Bend Kevlar back over the Crimp Support. Slide second Crimp
over Kevlar and Crimp Support and secure with tape for crimping after termination and polishing.
TERMINATE
Use the 2-Channel or 4-Channel Stripping Length Diagrams seen below (and located at the end of this
instruction) to Terminate and Polish the Fiber Optic Termini. Be sure to include a spring on each of the
fibers. For Termination and Polishing details, reference CAI-TERM-01.

CRIMP TOCABLE
Remove tape after polishing the Fiber Optic Termini. Use Kevlar Scissors PT-062 to remove any
excess Kevlar that is sticking out from the Crimp. Setup the Hydraulic Crimping tool PT-540 with the
Die Set PT-541. The Crimp Die with Stop needs to be placed on the bottom facing out and with the
Crimp against the stop as seen in the image below. Turn the knob clockwise on the Hydraulic Crimper,
so that the handles can be pumped to crimp. Place the cable in the lower Crimp Die with the fiber
facing out. Pump the handles until the Crimp Dies are touching. Release crimp by turning knob
counterclockwise.
After crimping, the Crimp should have a
hexagon shape as seen in the image below.

POPULATE THE INSERT
Insert the Fiber Optic Termini through the back and out the side
windows of the Spacer as seen in the image to the right.
Tweezers may help guide the Fiber Optic Termini into position.
Populate the insert according to the required configurations, crossed or straight as seen in the
diagrams below.

Apply Loctite 243 on the Socket Head Cap Screw threads per manufacturer’s instructions or
equivalent may be used and screw the Insert onto the Spacer using Hex Driver PT-503. Use
Torque Driver PT-590 with Hex Bit 5/64” PT-599 and torque the Socket Head Cap Screw(s) to the
values in the above Torque Table.
Pull Strain Relief to bottom of Spacer, apply Loctite on the Set Screw threads and tighten using Hex
Driver PT-500. Use Torque Hex Driver PT-590 with Hex Bit .050” PT-599 and torque to the values in
the above Torque Table.
Perform a visual check by looking through the holes in the Spacer to make sure that the fiber is not
twisted or kinked.
For the 2-channel Insert, ensure that
the white mark line on the Insert is on
the same side as the line on the
spacer. This Insert has two Screws.
The insert is NOT symmetrical, the
termini are slightly below the center
line. The insert should only go on one
way.
The 4-channel insert does not have a
white mark line since it can only go in
one way. This Insert has only one
screw in the middle.

FINAL ASSEMBLY
Place the Insert end into the Body Assembly. The tabs on the Spacer should engage with the slots on
the Body Assembly. Slide the Backshell into position and tighten by hand onto the Body Assembly
making sure that the Spacer does not turn relative to the Body. Insert the Plug Assembly onto the
Torque Fixture Stand PT-317. The fixture accommodates both the 2 and 4-channel plugs.
For the QSeal with Grip, torque the Backshell using Dial Torque-Measuring Wrench PT-506 with
Crow’s Foot Wrench PT-536 to the values in the above Torque Table. Make sure not to over torque the
Backshell as this will cause damage.
For the All-Metal Plug, tighten the Backshell using Dial Torque-Measuring Wrench PT-506 with Square
Driver Strap Wrench PT-415 to the values in the Torque Table above. Finally, tighten the Back Nut
using these same torque tools to the values in the Torque Table above.
NOTE: After torqueing, ensure that the insert is clocked properly in the Body with respect to the main
key.
