Dark marks appear in the middle of the optical cable splice

- Solutions: Use optical amplifiers or repeaters to boost signal strength, optimise cable routing to minimise signal attenuation, upgrade to higher quality fibre optic cables with lower attenuation coefficients. What Are the Most Common Fiber Splice Issues? Poor handling or cleaving leads to uneven fiber faces, causing high insertion loss. In a recent project, slight misalignment caused slowdowns until our OTDR testing pinpointed and corrected it precisely. Our customers are including China Telecom,China Mobile,China Unicom. These methods help locate and fix issues like breaks, poor splices, or damaged connectors. Or it could be caused by the quality of the connector itself, such as poor end-face geometry that doesn't pass the parameters defined by IEC PAS 61755-3 standards, including angle of the polish, fiber height, radius of curvature or apex offset. Fiber contamination Alignment error messages. High splice loss occurs when the fusion between two fibres does not achieve proper core alignment, resulting in excessive optical signal attenuation.
