Assembly Instructions for UTS1JC18LCN & UTS6JC18LCN

A - Cable preparation

1. Slide the backshell onto the cable allowing 50 cm at the end of the cable for stripping the cable. Make

sure to orient each component as shown in the UTS LC Component details section.

2. Using the cable jacket strip tool, strip the jacket to the dimension given in figure below, exposing the kevlar strength

members and fiber.

3. Using the shears, trim the kevlar strength members to the length given in figure below.

4. Fix the Kevlar using an adhesive tape on the “individual fibers” to facilitate the insertion of the crimp support.

5. Slide the crimp support (large diameter end first) over the fibers and the kevlar strength members until it bottoms on

the cable outer jacket.

6. Separate the kevlar strength members in two groups. Use an adhesive tape to fix the kevlar strength members on the

jacket.

Fiber tube protection: 100±1 mm

Kevlar: 40±1 mm

8. Before the instant adhesive begins to harden,quickly slide the ear clamp over the fiber, orient the Clamp

according the picture. Push the strength members back over the clamp until it bottoms on the rear flange of the

support.

7. Apply the instant adhesive on the fiber and cover the crimp support. (e.g. LOCTITE 480 PRISM).

9. Crimp the both ear of the Clamp using the Nipper. Remove the kevlar strength members using using the shears.

Check the good crimping by pulling manually.

11. Strip the fiber buffer according to your LC supplier recommendations and make sure to reach the final desired

lengths for the individual fibers as described on the pictures below.

12. Terminate the LC contact on the fiber according to your supplier instruction for gluing, cliving and polishing.

13. Fix the cable in a tool to avoid the rotation.

14. Plug the two LC: Make sure that each LC contact is in the right cavity A or B.

B - Backshell screwing for UTS1JC18LCN

1. Slide the blackshell and screw it using a 28 mm U-wrench. Tightened the backshell with a 4 Nm torque.

2. Control: Pull on the cable to ensure that the retention system bottoms in the backshell.

3. Screw the head nut using a 15 mm U-wrench. Tightened the head nut with a 2 Nm torque.

C - Backshell screwing for UTS6JC18LCN

1. You need a receptacle counter-part. Orient the polarization keys before you start mating the connectors.

2. Coupling plug with receptacle

3. Slide the blackshell and screw it using a 28 mm U-wrench. Tightened the backshell with a 4 Nm torque.

4. Control: Pull on the cable to ensure that the retention system bottoms in the backshell.

Recommendation

Use the caps, UTS618DCG2 for plug or UTS18DCG2 for receptacle to protect the LC contacts from surrouding

contamination.

Cleaning & Inspection

Cleaning and visual inspection of a termini endface is part of the good practices for fiber optics.

This is necessary to ensure the good optical performances of an LC contact inside a UTS LC connector.

Please note that most of the standard inspection and cleaning tool on the market can be used for maintenance of an LC

contact mounted in an UTS LC connector.

1 Inspection

A- Use a fiber optic video probe (magnification X200 minimum) to inspect the termini endface for contamination,

chips, pits, scratches and shatters in the core and in the inner of the cladding (see figure below).

2 Cleaning

A- Use a lint free tip moistened with 99% reagent grade isopropyl alcohol or optical quality cleaning fluid to clean

the termini endface. Always wipe in one direction, not back and forth.

B- Dry the termini endface with a dry tip.

C- Re-inspect the termini endface with a fiber optic video probe (Magnification x200 minimum) and verify that

the contamination has been removed.

D- If the contamination is still present then repeat step A & B.

E- If after repeated attempts, the contamination is still present and cannot be removed like minor scratches, chips

or pits then re-polish the optical contact (refer to the LC supplier instruction).

B- If dirt, debris or other surface contamination is identified then clean (see below).

E.g. Magnification X 400 of two multimode fibers

For more details, please refer to the acceptance criteria and cleaning procedures defined by IEC for multimode or

singlemode connector termini endface

Clean and good termini endface Contaminated or scratched termini endface

Safety Considerations

Safety glasses

A- Safety glasses to protect your eyes from accidental injury are strongly recommended when handling chemicals and

cutting fibers. Pieces of glass fiber are very sharp and can damage the cornea of the eye.

B- Glue

Glue may cause eye and skin irritation. Avoid contact with eyes, skin or clothing. Avoid prolonged or repeated

breathing of vapor. Use with adequate ventilation.

C- Fiber Precautions

Cleaved glass fibers are very sharp and can pierce the skin easily. Do not let cut pieces of fiber stick to your clothing or

drop in the work area where they can cause injury later. Use tweezers to pick up cut or broken pieces of the glass fibers

and place them in a debris container. Keep your work area clean.

D- Laser Precautions.

Laser light is invisible and can damage your eyes. Never look into the end of a fiber which may have a laser coupled

to the opposite end.
