STRIP CABLE
Strip cable jacket approximately 4” (100 mm) from end and place Crimp Support over fiber and Kevlar as
shown in the Stripping Length Diagram located at the end of this assembly instruction. Bend Kevlar back
over the Crimp Support. Slide Crimp over Kevlar and Crimp Support and secure with tape for crimping after
termination and polishing.
TERMINATE
Use the Stripping Length Diagram located at the end of this assembly instruction to Terminate and Polish
the Fiber Optic Termini. For Termination and Polishing details, reference CAI-TERM-01.

CRIMP TO CABLE
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
below. Excess Kevlar should be trimmed flush to the Crimp.

POPULATE THE INSERT
Insert the Fiber Optic Termini into the back of the Insert Cavities. Place the Termini Retainer Plate between
the 900 µm fibers making sure that the springs are between the Fiber Optic Termini and Termini Retainer
Plate. Apply a drop of Loctite 222 to the Socket Head Cap Screw and use Hex Tool PT-504 to screw the
Termini Retainer Plate into the Insert. Torque the Socket Head Screw to the values in the above Torque
Table using Torque-Measuring Head Drive PT-590 and Bit Size 2.5 mm PT-599. Use a pair of Long Nose
Pliers PT- 532 to ensure the termini are fully seated against the ball lenses.
NOTE: See diagram below for polarity configurations:
Straight configuration is defined as A1 to A1, B1 to B1. Crossed configuration is defined as A1
to B1. Four channel layout uses the same pattern.

FINAL ASSEMBLY
Use the Hex Driver PT-504 to align the key and install the insert into the back of the Body. The Insert
should protrude slightly from the seal and the Body. The seal should be visible around the Insert.
Slide the Wave Spring and Strain Relief into place. Place onto the QMini Torque Fixture PT-392. Hand
tighten the Strain Relief while on the Torque Fixture so that the fibers do not get twisted or kinked. Torque
the Strain Relief using the Adjustable Crowfoot Wrench PT-536 with the Dial Torque-Measuring Wrench
PT-506 to the values in the above Torque Table. Inspect the fibers by looking through the holes in the
Strain Relief making sure that the fibers are not twisted or kinked. Use Cable to pull Crimp to bottom of
Strain Relief. Use the Hex Driver PT-501 to tighten the set screws on the strain relief to lock the crimp into
place. Torque the Set Screws using Torque-Measuring Hex Drive PT-590 and Hex Bit 1/16-inch PT-599 to
the values in the above Torque Table.
Perform a final visual check by looking through the
holes of the Strain Relief to make sure that the fiber
is not twisted or kinked.

Slide the Washer and Cable Seal to the base of the Strain Relief. Slide the Coupling Ring over the Strain
Relief and Connector Body. Place the Plug on the Torque Fixture and hand-tighten the Coupling Ring.
Slide the Backshell into position and hand-tighten it. Torque the Backshell using the Crow’s Foot Wrench
PT-536 with the Dial Torque Measuring Wrench PT-506 to the values in the above Torque Table. Slide the
bend limiter into position and snap into place.
NOTE: For Cable Diameters 7.6mm – 10.5mm
Apply an adhesive (Loctite Stik’N Seal Outdoor Adhesive or similar for rubber applications) on the inside of
the Heat Shrink Bend Limiter. Slide it up towards the Backshell and heat shrink it onto the Backshell
leaving a small gap between the top of the Bend Limiter and the Backshell for the Lanyard.
