Fiber Kit Assembly

1. The kit must be put on in the following order: Boot → Sheath Ring → Crimp Ring → Rear Post Ring → Spring.

2.Strip the 3.0mm sheath of the optical fiber cable, the stripping length is 2.7cm (+-0.3cm), the Kevlar scissor type is 0.5cm, and the bare fiber is 1.4cm (+-0.1cm).

Glue injection:

Put the 353ND mixed glue into the syringe, and inject the glue from the tail until it comes out from the ferrule interface.

Curing:

Place the inserted ferrule on a 100°C oven for 20 minutes to cure.

Fiber Patch Cord Assembly

polishing

1. Cut the fiber beyond the ferrule, then lightly sand the glue with sandpaper.
2. Put the ferrule into the fixture, adjust the polishing pressure, and start polishing according to the polishing direction: for each batch of products, check whether 80% of the samples can pass the interferometer detection before large-area polishing. If not, investigate the course and adjust the craft
3. Interface inspection: The interface must be free of scratches, white spots or glue residue

IL/RL testing

To ensure the accuracy of test results, the instrument must be calibrated annually by the National Communications Agency.

Bale

After all tests, the jumpers will be packaged according to the customer’s needs. Usually, each jumper wire will be in a plastic bag, then 10-50 in a bubble bag to make it more secure.
