1 edit | What needs to be grounded?
I had FiOS and am confused as to what required grounding. You have non-conductive fiber coming in the from the street and my install looked like the ONT itself is grounded through the AC/DC adapter. So what needs to be grounded? |

1 edit | From what i see of the installs they still ground the ONT to the 6 wire the same as we would a ground block with cable... So far I have seen quite a few installs grounded to water pipes and a few not grounded at all.
Edit: To say that that there is a distance limitation also... |

The metalic sheeting that protects the fiber drop needs to be bonded and grounded per NEC |

The AC/DC adapter ground doesn't count and all communication systems needed to be bonded to the common electrical ground to meet code requirements, simple as that.
Here's a general summary of what's required:

There is NO metal in the drop. There are some drops that are buried that have a metal wire bonded to the side. This is used for tracing only and is not attached at either end. |

My point is if it's fiber, what are you grounding? From some other posts, I gather there is a metal reenforcement in the fiber drop. |

the fiber its self is. But the armored cable sheath that its enclosed, needs to be, unless they are refering to the fiber drops that are inside conduit, which i dont think had tracer wire sheathing or anything. |

no...... there is no metal in a fiber drop. some have a tracer attached to the side but there is no metal in the drop. I have cut and stripped many of them. |

| Goose you have no idea what you are talking about.THERE IS NO METAL IN A FIBER LOOP. There are fiber loops with a tracer on the side used for locating on buried jobs. |

Educate yourself. Having spliced and cut down many of these
THERE IS NO METAL IN THEM! The are wrapped in Kevlar. Also very few of the tracable buried service feeds are actually in use. |

You are absolutely right that there are no conductive components of fiber(glass,rubber,plastic). But Verizon is required to properly ground ONT, if outside(lightning), the AC/DC outlet will only ground your ONT if it's mounted inside because electricity to the home is already grounded. |

Buried drops that are used in Florida that do have a 24ga "tracer" wire ARE grounded at the ONT or to the MGN at the house per Verizon's Bonding and Grounding Rules. There were some early installs (2005) that the fiber did not have a tracer so a 3 pair copper drop was buried along side of the fiber for locating purposes but those copper drops were not connected to the house they were just cut off at ground level.
Trust me we are in the LIGHTNING CAPITAL and we (Verizon)along with Tellabs have tried everything possible in trying to prevent ONT's from getting taken out by lightning. In fact the new 612A that is coming out is a result from Tellab's testing in Florida, 612A will have additional surge suppression built into the POTS connections. |

A conductive material is going from the inside to the outside of a building. It needs to be grounded. |

Its not so much the fiber connection that NEC is worried about, as the glass is not conductive, however, the FTTH Unit on the side of the house converts the digital light signal to digital electrical signal, which is then delivered to the TVs for FiOS TV via RG-6 Coaxial cable, Telephones Via round 4 pair in older homes, in more recent homes CAT5e is the normal for home phone wiring. Both phone and coaxial drops must be grounded. grounding through the ONT grounds all services offered by FiOS internet, phone and TV. When Verizon comes in and installs there services, they disconnect the cable tv drop and the phones POTS line, and run the wires to the ONT, thus disconnecting any ground from the internal wiring of the house. It might not seem like a huge problem, but not grounding the coaxial alone can turn into a horrible issue. Appliances such as TVs, answering machines, fax machines, computers can all back feed voltage through the respective lines. as a former cable TV tech, I experienced many service calls, that were for "bad/Snowy picture." I would start my trouble shooting checking signal levels through the house, and at the main splitter, and would receive a shock, usually not strong but once it was a good wake up call. Come to find out, a tv in the customers home would have a issue called a hot chassis, and would back feed voltage on the coax, trying to get to ground. One home had no ground and actually did damage to the cable main line tap by feeding ac power back on to the dc powered system, the tap melted like it was solder. They say electricity travels the shortest path to ground, i would say it takes what ever path it can find, with most going the shortest route. Also its safer to ground something that might not need it, then "knock on wood" a fire happens at a home and the fire investigator find that an electrical system "high or low voltage" is not grounded that could screw you out of your home owners insurance. leveling blame on the company that was responsible for verifying there equipment is grounded. |

I think it's pretty clear that from BrightHouse's perspective it's Verizon that needs to be grounded! |
