Re: Does verizon need to ground fiber?
The ONT converts the light signal to something that your home can use:
Coax - for TV and/or internet.
rj45 - for internet.
rj11 - for phone.
Each of these require power. The ONT is providing it through the power connection made in the house its attached to. Before switching to fios, the power would have been provided by the service provider of each of these.
I honestly don't get why they don't ground it to the house's power, rather than doing this external grounding. |

1 edit | Must be the NY techs...
When the techs were here doing my install, they ran a #14 ground wire outside and bugged it onto my ground rod wiring. I`m not an electrician, but it looks pretty durn good to me.
no problems with getting zapped either LoL

ps... somehows I think the NY PUC was prodded into investigating this... *cough* cv *cough*
edit--- just looked at the photos... there is some REAL shoddy work done in the photos... hard to believe thats a union guy, but anythings possible |

1 edit | said by Pathfinder  :Most codes require ground wire to be at least 10 guage. Just checked again, says 12 awg on jacket, I was wrong...
I also checked out the NEC 2008.. they specify a minimum of 14awg for fiber and comms circuits. Since the input voltage and current is relatively low, I would think a #12 or 14 would be sufficient..
nec2008 quoted above... 770.100.A.3 on the first pic, and 800.100.A.3 on the 2nd

Here | It's not the service voltage. It's foreign voltage (lightning and utility). The gauge usually allows only a certain amount of protection. Meaning the more services protected the higher the gauge needed. 10ga is the way to go. |

1 edit | yea, #10 to the ground rod at min... I have #6 here from the main box to the rod, vz just put a bug on it for the fios with #12
so the nec code is wrong?

Grounding is not to protect from being hit by lightning. It's to dissipate the static that could attract lightning and give a low resistance path in case of a electrical short.
I learned that building a home weather station when I had to put the mast up I checked what was needed for lightning protection. |

Here | Fiber may be different from POTS but all telephone interfaces have carbon or gas tubes in there specifically with lightning protection in mind. The ground is definitely there in those for lightning. |
