Repair Measures for Uneven Outer Diameter of Optical Cables

Uneven outer diameter in optical cables can be addressed through precise diagnostics, targeted splicing, and protective measures to restore performance and prevent future damage.

Diagnosing the Issue

Uneven outer diameter often results from extrusion inconsistencies, mechanical stress, or environmental factors during installation or operation ( ). To accurately locate affected sections: Use laser micrometers during production or OTDR (Optical Time-Domain Reflectometer) in the field to detect micro-bends, diameter fluctuations, or signal loss points ( ). Inspect visually for kinks, bulges, or irregular jacket thickness, which may indicate uneven extrusion or mechanical deformation ( ).

Repair Techniques

Cable Preparation

Carefully expose the damaged or uneven segment without stressing the fiber core. Strip the outer jacket and buffer layers to access the glass fibers while maintaining perpendicular edges for splicing ( ).

Fusion Splicing

Use a fusion splicer to join fiber ends, ensuring minimal signal loss (typically
