Fiber Optic Connector Termination: Fiber Polishing Film

A little but crucial step in the manufacturing process, crimping fortifies the cable assembly and shields the fiber. Reliability and long-term performance are directly impacted by maintaining the optical connection, which is made possible by using proper crimping procedures with a Fiber Crimping Machine.

Suggestions for optimal crimping methods

The crimping procedure comprises three components: the connector body, a metal crimping sleeve or ring, and the material to be clamped, which is often the cable's strength part, aramid yarns. Use these pointers to enhance your crimping processes:

Use the right crimp tool: To get the optimal crimp and maximum pull force for that assembly, the connection manufacturer specifies the die set, crimp sleeve, crimp force, and crimp tool for each connector body. It is vital to utilize the appropriate instruments and parts. The experts at the connection maker considered mechanical tolerances while designing this "match made in heaven."   Crimping and Fiber Polishing Film increases the contact surface area. These particulars increase the assembly's maximum draw force.

The incorrect die set or crimp tool might cause harm to the cable assembly since the crimp will probably be too light or too hard. The connection may be crushed by a forceful crimp. Glass optical fiber damage is also a possibility if this structure sustains damage. As an aside, you can utilize an automated crimp tool, which provides repeatability and produces superior process control with less operator fatigue, or the manual crimp tool that is recommended by the connection maker.

Teach your operators–Remember, every part needs a unique Fiber Crimping Machine, die, and sleeve. Never combine different components! There may be ten or fifteen die sets with different tools on some manufacturing lines; the operator has to know which tool to use for each connection. Here's some advice: Give your tools a number or color code to help you recognize them for each unique cable assembly product. By doing this, you can make sure that your operators always utilize the appropriate tool.
