the verizon fios is no different than copper being used from comcast and twc,so you need full power to get the cable running.for example,when you unscrew the copper cable line to the adapter in your home,go ahead and touch that copper cable line thats coming in your room and you will feel the power of cable.i would imagine its the sameway with fiostv with the fiber optics,so the power must need be grounded.but it sounds like to me that bright house are just whining and complaining trying to use the govt of fl to go after verizon because they offer better services than bright house.bright house knows,thats why they are using this cheap trick against verizon there chief competitor
If you are feeling any power, electric current, or shock coming from the copper pigtail or the connector, then you have a grounding issue my friend. You may need to call customer service or possibly an electrician to fix that.
