1. A communications cable comprising: a pair of conductors, and an outer cable jacket surrounding the pair of conductors, said pair of conductors comprising a first conductor insulated by a first insulating layer, and a second conductor insulated by a second insulating layer; wherein at least one of the first insulating layer and the second insulating layer contains at least about 95% w/w of perfluoroalkoxy alkane (PFA),
wherein the first and second insulating layers have a substantially smooth interior surface and are in contact with the first and second conductors along an outer circumference of the first and second conductors, respectively,
the outer cable jacket surrounds the pair of conductors, and
at least one of the first insulating layer and the second insulating layer have a dielectric constant below 2.1 when measured by the resonant cavity perturbation technique of ASTM D2520 Method B.
