Cable techs routinely use a splitter to drop levels when they really are too hot. If attenuation is really needed why not use one of these selective attenuators and just drop rcv levels ? Using a attenuator that also effects TX seems to make no sense.
Cost. Selective attenuators are more expensive and less commonly used then splitters. Plus it's more inventory to stock, track, and maintain.
In addition, it's very rare the forward levels are too high without the upstream levels being too low. In most cases, if they are, it's a distribution system balancing issue.--
If it's important, back it up... twice. Even 99.999% availability isn't enough sometimes.
