You've missed the main problem with powered copper - water.  Water WILL get 
into the cable, no matter how fancy the connector and how properly it is 
torqued.  It may take 50 years if done right or a few days if done wrong, 
but water always wins.  Once the water is in the metal starts corroding. 
Powered cables corrode much faster than unpowered ones.  Then, they stop 
working or pass noisy signals.

In short, water is the bane of powered copper installations and is one
of the big reasons PON (Passive Optical Network - Ed.) is so much more
reliable than copper.  With nothing powered between the OLT and ONT,
there is nothing to get damaged by water.  When my FiOS drop was
installed, the installer literally fished the drop cable out of a foot
of water in the access vault, removed the protective cap from the drop
cable, screwed on the fiber to my house, and dropped the whole thing
back in the water.  Even when water seeps into this connection, it'll
have little effect on the glass and plastic fiber cable assembly.

If we start passing power along with the fiber, the eliminates one of the 
major advantages of PON - lower maintenance costs due to no powered stuff in 
the field.

Now, I did see that the drop cable does have a ground wire attached to it. 
It is grounded at the access vault and my house.  It's purpose is to allow 
the cable to be located.  It doesn't pass power or signal.  Even if it 
corrodes (and it will), it'll still show up when the cable locator is passed 
over it.
