I've been told this is very important in HFC solutions (hybrid fibre
coax).
Operationally though, having APC is a hassle. I know of companies who
mandated APC for a few years for all installations, but then reverted back
to UPC due to operational problems (people putting UPC cables into APC
ODFs etc).
So while APC might be technically superior when properly installed, it's
not always better when looking at the whole "system".
