- CABLE CONSTRUCTION
- Conductor: The conductors shall be solid, annealed and bare copper with a diameter of AWG23 and
minimum acceptable diameter shall be 0.546mm.
Insulation: Each conductor shall be insulated with HDPE or FEP (In case of Plenum grade). The insulation shall be uniform and shall not have any defects. The diameter over the insulation shall be maximum 1.22mm.
Non-continuous shield: The non-continuous aluminum tape shall be applied over the core wrapping to
increase alien crosstalk performances.
Sheath: The flame retardant PVC or LSZH(Low Smoke Zero Halogen) compound colored grey or other
colors shall be applied over the cable core.
