Pros & Cons

Pros

  • ✓ 40Gbps at 2000MHz bandwidth headroom for LAN, server, and data-center runs
  • ✓ F/FTP shielding: 4 aluminum-foil twisted pairs cut EMI and RFI on long pulls
  • ✓ Bare copper core with gold-plated RJ45 ends, not copper-clad aluminum
  • ✓ Direct-burial rated PVC jacket handles outdoor, basement, and crawlspace routing
  • ✓ PoE-capable, so IP cameras and access points run on one 20ft cord

Cons

  • ✗ Round shielded jacket is stiffer and harder to route than flat Cat 6 cable
  • ✗ 20ft fixed length forces slack coils in short runs like desk to router
  • ✗ Grounded shielded keystone jacks needed to actually use the F/FTP shield
  • ✗ No stated warranty terms; check the listing before buying for permanent installs

DDMALL's networking lineup sits within the broader category mid-tier; price and specs are the deciding factors over brand loyalty here.
