As an indispensable component of the optical fiber communication system, the precision of the production process of the conventional fiber optic patch cord is directly related to the performance and quality of the patch cord. The following are the main steps of the conventional fiber optic patch cord production process:
First, cut the optical cable. According to production requirements, use professional aramid scissors to cut the optical cable to the appropriate length and perform simple coiling. This step ensures that the length of the optical cable meets the requirements of subsequent processing and practical applications.
Next is to wear loose parts. Put loose parts such as rubber sheaths, heat shrink tubes, support tubes and springs on the optical fiber in a certain order. The accuracy of this step is crucial for the smooth progress of subsequent processes.
Then, pre-process the optical fiber, that is, strip the fiber. Use wire strippers or fiber strippers to strip the outer skin and coating of the optical fiber. When stripping the fiber, you need to pay attention to the strength and angle to avoid damage to the optical fiber itself. The quality of stripping directly affects the transmission performance of the optical fiber.
Then, glue is prepared and injected. Prepare special glue for optical fiber (such as 353ND AB glue) and inject the prepared glue into the tail handle of the ferrule (or ferrule). Then, insert the stripped optical fiber into the ferrule filled with glue, and ensure that the optical fiber is exposed to a certain length. This step ensures a firm connection between the optical fiber and the ferrule.
Next is heating and curing. Put the ferrule with optical fiber and glue into the curing oven for baking to completely cure the glue. The curing temperature and time need to be determined according to the type of glue and the material of the ferrule. This step enhances the connection strength between the optical fiber and the ferrule.
After curing, remove the glue and grind. Use a cutting knife to cut the cured optical fiber head neatly and remove the excess optical fiber exposed in front. Then, use the glue-removing sandpaper to polish the optical fiber head to remove the glue residue on the head of the ferrule. Then, put the optical fiber head after degumming on the grinding fixture and use the grinder to grind it so that the end face of the optical fiber head reaches a certain flatness and finish.
Then comes the end face inspection. Use an end face inspector with a magnification of 400 times to check the polishing effect of the ferrule end face. The end face needs to be flat, smooth and free of defects such as black spots and scratches. This step ensures the transmission performance of the fiber jumper.
Next is assembly. Assemble the polished ferrule and loose parts (such as tail sleeves, grounding ferrules, etc.) into a connector, and use crimping pliers or crimping machines to crimp the tail sleeves. This step ensures the stability and reliability of the connector.
Finally, the conventional fiber optic patch cord is tested and packaged. Use an insertion return loss tester to measure the main data insertion loss and return loss of the fiber head. After the test is qualified, QA spot checks are carried out to further control the quality. Finally, the qualified products are packaged and packed to ensure that the products are not damaged during transportation and storage.
