My Home Fibre Network Disintegrated

Home internet cable turns to dust—'military grade' roasted

TLDR: A “military grade” home internet cable crumbled to dust, forcing a tape-and-pray rescue. Commenters roasted the marketing, floated ozone and humidity as culprits, and preached conduits and patch panels—turning a DIY disaster into a cautionary tale about storage, materials, and not burying cables without a backup plan.

One home tinkerer lifted a cable in his bomb-shelter server nook and watched his “MiLiTaRy GrAdE” fiber line turn to cookie crumbs. The armored jacket from FS.com disintegrated in seconds, exposing wiry guts, and every attempt to tape it back just triggered more breakages. Cue the internet piling on. The spiciest take: “’Military grade’ is snake oil,” snarled one commenter, roasting the marketing hype while others posted memes dubbing it “crumb‑grade.” Another camp went full science: one reader wondered, “Could something be generating ozone in there?” — suggesting a reactive gas might be eating the plastic. A third group chimed in with lived experience: “soft-touch usb cables… disintegrate like this,” blaming certain rubbery coatings that turn to dust over time, even untouched. Practical voices arrived to clean up the mess: humidity blamed, storage with tight coils slammed, and a chorus sang “install conduit or cry,” arguing you should run cables through replaceable tubes rather than burying them under concrete. The original poster’s regret was real: skip the armoring for moving parts, use a wall patch panel, and swap cheap-to-replace lines like LSZH (low-smoke, safer plastic) when needed. Outcome? A home office on life support—and a comment section at full burn.

Key Points

  • An armoured fiber optic cable’s outer jacket crumbled and exposed internal shielding when moved after long-term storage.
  • The cables were purchased from FS.com in 2022 and had been stored tightly spooled (≈5 cm radius) and hung for about three years.
  • The failed cable was recently connected to a UDM for an SFP+ link; movement appears to have triggered multiple jacket failures.
  • The author attempted repairs using 3M rubber tape 23 and Temflex 160 vinyl tape, but the process caused further damage and sharp bends.
  • The author recommends a patch panel with LSZH patch cords to avoid moving buried fiber runs and facilitate future maintenance.
