Routing cables carefully in trays or conduits avoids sharp bends and stress. Hybrid cables often have multiple fibers and mixed connector types; maintain recommended bend radius for both cable and connectors to prevent microbending or fiber break.
Secure Connectors and Avoid Excess Strain
At cable entry points, connectors should be firmly seated and strain relief applied. Uncontrolled pulling or twisting causes misalignment, increased insertion loss, or damage to connector ferrules.
Cleanliness Is Critical
Multi-fiber connectors are susceptible to dust or debris. Every time connectors are connected inspect end faces with an inspection scope. Clean using fiber-safe swabs. Do not touch facing surfaces. Clean before connection especially if testing critical loss or certification.
Periodic Testing and Monitoring
After installation and after any maintenance moves run tests to ensure insertion loss, return loss, skew, and continuity are all within specification. Document results. Compare against baseline to detect degradation over time.
Labeling and Documentation
Label both ends of trunk cables, core counts, connector polarity, and type. Record connector gender (male/female), fiber mode, and intended usage. Good documentation helps avoid confusion in large installations.
Safe Storage and Transport for Spare Cables
Store spare hybrid trunk cables in protective reels or racks, avoiding sharp bends or crushing. When transporting, ensure covers for connectors to avoid contamination and damage.
