FTTC speed issue copper cable problem? Fibre

Thanks for the information. Surely the effect of the fibre optic through FTTC is effectively to move the exchange closer to the property.

Method of using a shielding means to attenuate

Apr 30, 1985Copper is known to be an economical and effective radio-frequency shielding metal, but has the disadvantage of darkening and surface oxidizing so that it is, per se, unsuitable for use as an effective metal shield. Pure copper shielding also oxidizes, and loses electrical conductivity at the mating surfaces of the enclosure.
