BACK NUT ONLY ASSEMBLIES (900µm Cable Option)
CABLE PREPARATION
Slide the components onto the cable in this order.
(See image on right):
1. Back Nut
2. Spacer
3. Wave Spring
TERMINATE
Strip approximately 1-inch (25mm) of buffer off the fiber. Be sure to include a spring on each of the
fibers. For Termination and Polishing details, reference CAI-TERM-01. When Terminating, apply Epoxy
EPO-TEK-353 inside the base of the Termini so that the 900µm Buffer Fiber Jacket stays in place.
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-503 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 5/64”
PT-599. Use a pair of Long Nose Pliers PT- 532 to ensure the termini are fully seated against the ball
lenses.

FINAL ASSEMBLY
Use the Hex Driver PT-503 to align the key and install the insert into the Jam Nut or Flange Adapter
Body. Rotate the body clockwise until the insert locates internal key. Push the insert forward. The Insert
should protrude from the front face of the body to indicate it is seated properly. The seal should be
visible around the insert as seen in the image below.
NOTE: Orientation of the connectors is seen below
Slide the Wave Spring and Spacer forward and secure them flush against the back of the Receptacle
Body. Place assembly in the 4" Drill Press Vise with 2 x Machined Plastic Jaws with Groove PT-591
and use the Crow’s Foot Wrench PT-536 with the Dial Torque Measuring Wrench PT-506 to torque the
Back Nut to the values in the above Torque Table.

LOW PROFILE BACKSHELL ASSEMBLIES (4x2mm Cable Option OR4.5mm –
7.5mm Cable Option)
CABLE PREPARATION
Slide the components onto the cable in this order
(See image on right):
1. Back Nut
2. Strain Relief
3. Wave Spring
STRIP CABLE
For a 4x2mm Cable Option
Strip the fiber jacket leaving extra Kevlar. Slide
the 900µm fiber and Kevlar thru the hole in the
4-Channel Crimp Support. Slide the fiber jacket
into the hole up to the front face of the support.
Repeat for each channel. Wrap the Kevlar
around the 4-Channel Crimp Support. Install
the Crimp over the 900µm fibers and Secure
with tape for crimping after termination and
polishing.
For a 4.5mm – 7.5mm Cable Option
Strip cable jacket approximately 3” (76 mm) from end and place Crimp Support over fiber and Kevlar so
that it stops at the end of the jacket. For a 4.5mm to 7.5mm Cable Option, 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 Stripping Length Diagram seen below 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 below.

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-503 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 5/64” PT-
599. Use a pair of Long Nose Pliers PT- 532 to ensure the termini are fully seated against the ball
lenses.
FINAL ASSEMBLY
Use the Hex Driver PT-503 to align the key and install the insert into the Jam Nut or Flange Adapter
Body. Rotate the body clockwise until the insert locates internal key. Push the insert forward. The Insert
should protrude from the front face of the body to indicate it is seated properly. The seal should be
visible around the insert as seen in the image below.

Slide the Wave Spring and Strain Relief into place. Hand tighten the Strain Relief. Check the fiber
through the holes in the Strain Relief to make sure they are not twisted or kinked. Place assembly in the
4" Drill Press Vise with 2 x Machined Plastic Jaws with Groove PT-591 and use the Crow’s Foot
Wrench PT-536 with the Dial Torque Measuring Wrench PT-506 to torque the Strain Relief to the
values in the above Torque Table. 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. Hand tighten the Back Nut and then Torque it using the same torque tools to
the to the values in the Torque Table above.
