ATS Cables CAT5e Plenum (CMP) Cable

Bottom line: The ATS Cables CAT5e Plenum Cable ($104.99 on Amazon as of 2026-10-06): Plenum CMP jacket is fire-rated for air spaces above suspended ceilings or below raised floors; main trade-off: copper-clad aluminum conductor, not solid copper: more resistance on long PoE runs.

Pros & Cons

Pros

  • ✓ Plenum CMP jacket is fire-rated for air spaces above suspended ceilings or below raised floors
  • ✓ 350MHz bandwidth on 24AWG 4-pair UTP covers Fast Ethernet and Gigabit runs

Cons

  • ✗ Copper-clad aluminum conductor, not solid copper: more resistance on long PoE runs
