5. Cable Splicing
Splicing joins cable ends to restore continuity or extend runs. In fiber, it demands microscopic precision; in copper, it demands strong, protected connections.
Why It's Important
Every splice is a potential failure point. Done right, it disappears. Done wrong, it haunts the whole segment.
How to Improve Cable Splicing Skills
Master preparation: Clean cuts, proper stripping, and meticulous handling prevent damage before it starts.
Use the right gear: Quality cleavers, splicers, heat-shrink, and enclosures pay for themselves.
Protect against the elements: Seal, cushion, and strain-relieve—especially outdoors and underground.
Verify loss: Measure insertion loss and reflectance after every splice; rework if it’s out of spec.
Train and certify: Refresh skills regularly and follow current standards and procedures.
Respect safety: Eye protection for fiber shards, proper disposal, and safe power practices are non-negotiable.
Precision in the small things keeps the big network humming.
