Beldfoil shield on each pair is bonded to PVC jacket to aid in stripping. The 2 pairs are then twisted/cabled with synthetic fillers and an 18awg stranded (19x30 stranding) tinned copper drain wire to form a core, then wrapped in a nylon spiral wrap to preserve core structure, then covered in an overall Beldfoil shield (100% coverage aluminum foil/polyester tape backing), with nylon ripcord, all covered in a black PVC jacket.
