Common Errors: Misalignment, insufficient cleaning before the splice, or incorrect fusion splicer settings. Impact: Results in weak connections and increased attenuation. How to Avoid It: Always clean bare fibers immediately after stripping—not before—then cleave for a perfect end. Based on insights from Jonard Tools, here are the five most common mistakes—and how you can fix them right at the start of a job, using the right tools and procedures. Not Cleaning Fiber Connectors Properly What Happens: Dust, oils, and debris on connector end faces cause insertion loss and back. The performance of a fiber optic splice is determined by a number of factors, including the quality of the fiber, the cleanliness of the splice, and the techniques used to make the splice. However, splicing is not a simple task and it requires precision, care, and proper equipment. If you make any mistakes, you could end up with poor performance, higher costs, and safety hazards. Get the wrong connector type, the wrong polish, or skip proper fusion splicing technique—and you're looking at elevated signal loss, increased back reflection, and a. The causes are usually lack of training, lack of practice and lack of understanding of what is a “good” and/or “acceptable” fiber optic connector.
