Happy New Year's Day 2025!

Explains the three lightning damage mechanisms, which ones all-dielectric cable truly eliminates, and the four overlooked places where metal — and risk — still remain on the route.

When engineers specify a solution for direct burial in rocky soil, installation alongside high-voltage lines, or routing through rodent-infested terrain, they often reach for a ruggedized option known as SWA fiber optic cable.

A substandard cable may pass initial continuity tests but fail prematurely due to corrosion, water ingress, fiber degradation, or mechanical fatigue. Since you can’t X-ray every reel on delivery, proactive verification before purchase is essential.

An unarmored cable is built like an onion—layered, purposeful, and optimized for protection without metal. While designs vary by application (indoor, outdoor, riser, plenum), most share these fundamental components:
