(57) It comprises a combination of colour-coded pairs (1), cabled in units (2) of three
or four pairs, said combination of pairs being covered with a plastic protection tape
(3), wound helicoidally, on which is a drain wire (4) and on the outside of this is
a tape (5), metalized on one side and covered with insulating material on the other,
on top of which is a cord (6) for tearing the final cover (7) sealing the whole array
and which is made of PVC or other material with low halogen content. In this way,
signal-coupling imbalances at high-frequency can be offset, making said cable suitable
for transmitting bidirectional digital signals and in particular xDSL or broadband
systems, enabling interoperability of new and existing systems in the cable and making
maximum use of the systems it uses, at the same time optimizing the loop length by
its low level of longitudinal attenuation loss and low level cross-talk noise.
