Whaaat???
You maybe messing up with networked cables such as MIT, Transperent that kind-a shunt reactance in the middle-way to the signal but at the same time increase the current loss so not every time the system will benefit from them...
Cable networks are 100%passive and I've never seen any active ones if that what you realy mean.
In my experience MIT or Transperent you should use when you need to tame hi-res brightness.
