The varying twist ratios among the pairs and the physical orientation of
the pairs are the primary drivers behind limiting signal loss and
crosstalk ... However, while solid-core is *usually* cheaper, when it's
in plenum-rated jacketing (often the case), the jacket material makes
the whole much more expensive. yes, you can get cheaper stuff that's not
plenum rated, but to my way of thinking, if it's good enough for
commercial code requirements, then it's probably worth the expense. On
the other hand, I wouldn't outfit my house with Belden's MediaTwist on a
bet ... I'd like to eat more than ramen noodles this year.
