Single-fiber PC ferrules, developing a polishing process:
Step 1. Define your objectives, especially measurement criteria and process yields.
When developing a polishing process, it’s important to clarify your acceptance criteria and targeted yields – and have the ability to accurately measure and quantify pass/fail results. For example, do your polished ferrules need to meet an end-face geometry specification such as those specified in Telcordia GR-326? Also, virtually all polished fiber optic ferrule end-faces must meet SOME visual appearance specifications. What criteria will you use to determine if your polishing results are acceptable or not?
When developing a polishing process, we highly recommend that your initial targets are to meet GR-326 geometry requirements and IEC 61300-3-35 visual requirements – with a minimum yield expectation of 95% passing.
