25-pair Ethernet cable FinMark UTP CAT5e is used as connection cable between two switch nodes, as well as to provide connection of multiport active network devices to patch-panels inside of switching cabinets. Cable shell is made from polyvinylchloride elastron (PVC) of grey color. Outer cable diameter is 13.2 mm.

 

The main electric properties:

  • Impedance (100±15) Ohm;
  • Direct current resistance 94 Ohm/km;
  • Propagation velocity 0,68×s.

 

Mechanical properties:

  • Cable consists of 25 pairs integrated by 4 pairs of conductors (6 layers), interweaved with color coding tape. 25-th pair has additional polyvinylchloride shell and serves as centering cable element.
  • Conductor material: copper wire of 0.51 mm in dia (24 AWG).
  • Insulation of conductor – polyethylene, conductor diameter in insulation is 0.9 mm.
  • Temperature range:
  • installation -10 °C … +60 °C;
  • operating -30 °C … +60 °C.
  • Minimal bending radius:
  • During erection (dynamic) ≥ 8 x cable diameters.
  • After erection (constant) ≥ 4 x cable diameters.
  • Tensile load ≤ 200 Н.

In each of 6 layers of cable there are 4 conductors with application of conventional color identification of conductors:
pair 1: white-blue ⁄ blue
pair 2: white-orange ⁄ orange
pair 3: white-green ⁄ green
pair 4: white-brown ⁄ brown
pair 25: white-blue ⁄ blue

Packing: Cable is wound on coils by 305 m (1000 feet).
