25 Pair Cables

24 AWG U/UTP Multipair Sheathed Cable

CopperOn VOICE cables consist of 0.51mm Polyolefin insulated conductors formed into one or more units of twisted pairs. The units are identified with coloured binders and are assembled to form the cable core. The core may be protected with one or more layers of dielectric material and is covered by a protective LSHF sheath.
