F/UTP - twisted-pair cable (shielded)

F/UTP twisted-pair cable for structured cabling systems.

Designed to transmit signals with a frequency of up to 500 MHz (category 6a) in networks according to ISO/IEC 11801 with an operating AC voltage up to 145V.

In the outdoor version, the cable design can include steel wire rope.

Structure
  1. Current-carrying copper conductor;
  2. Conductor insulation;
  3. Tinned copper conductor;
  4. Foil screen;
  5. Cable sheath;
  6. Crossing (for cable with category above 5e).
