8. Installation Guidelines

• The cable should be routed away from sharp edges, high-temperature sources, and strong electromagnetic interference (EMI) environments.

• Avoid excessive pulling, bending, or twisting during installation to prevent fiber breakage or performance degradation.

• Connector mating should be performed with clean, dry connectors; use approved fiber cleaning tools to remove dust or debris before mating.

• The cable should be secured with appropriate cable ties or clamps, ensuring no excessive pressure on the cable jacket or connectors.

• Follow standard fiber optic installation practices for termination, splicing (if required), and testing.

9. Testing and Quality Assurance

• Each cable undergoes 100% factory testing for insertion loss, return loss, and visual inspection of connectors and fiber continuity.

• Testing equipment is calibrated to IEC/ANSI traceable standards.

• Visual inspection includes checking for connector scratches, contamination, and proper fiber alignment.

• Random sampling for mechanical and environmental performance testing is conducted per quality control procedures.

10. Dimensional Reference (Typical)
