1. Cut the optical cable: Mainly use aramid scissors to cut the length of the optical cable as needed, and then simply wrap it in a circle.
2. Worn parts: Mainly threading various loose parts on the optical fiber in advance to facilitate subsequent operations. When threading, the rubber sheath, heat shrink tube, support tube and spring are in order. Pay attention to whether the direction is correct.
3. Adhesive: Mainly use auxiliary tools to evenly bond part B in 353 at a ratio of 10:1 to minimize bubbles.
4. Optical fiber insertion: First use a fiber stripper to peel off the outer skin and coating of the optical fiber, then use a syringe or dispenser to inject the prepared glue into the tail handle of the ferrule, and then manually string the optical fiber into the ferrule filled with glue. Expose part of the optical fiber.
5. Heating and curing: Put the worn fiber ferrule into a curing oven and bake it. Until the 353rd glue is completely cured.
6. Glue removal: First use a cutter to cut off the cured fiber heads, cut off the excess fibers exposed in the front, then place all the fiber heads on the grinding fixture, and then polish them with glue removal sandpaper to remove the ferrule heads. the goal of.
7. Grinding: Grind the fixture after degumming on the grinder. The general process is 9u 3u 1u 0.5u, and there is a certain relationship between grinding time and pressure.
8. End face inspection: Use an end face inspector with a magnification of 400 times to check the grinding effect of the ferrule end face. Generally, end faces with black spots and large scratches are considered unqualified and need to be reground.
9. Assembly: Assemble the ground ferrule and parts into a connector, and use a crimping plier or crimping machine to crimp the tail sleeve.
10. Test: Use an insertion return loss tester to measure the main data of the fiber head, insertion loss and return loss. Generally, the insertion loss of single mode is required to be less than or equal to 0.3dB, and the return loss is greater than or equal to 50dB. For optical fibers with higher requirements The jumper needs to undergo 3D interference testing (the three main data are vertex offset, radius of curvature, and fiber height)
11. QA sampling inspection: QA personnel conduct sampling inspection of qualified products after testing to control quality.
