| Fiber "drop wire" grounding This is just something that has had me wondering -
Why does the fiber optic "drop wire" have to be grounded (at the entry to a residence)? |

kudos:1 | There's a steel messenger wire holding up that fiber optics I'm sure. |

| Thanks for the reply Paul.
I ran into a FIOS installer today and asked him the same question. He said there is NO metal in the fiber "drop" wire. He seemed to feel it was just something left over from the past. |

kudos:18 | There is another reason for the wire. It acts as a tracer for locating underground services.
BTW, the FIOS installer was incorrect. FIOS installation practices in most situations require that wire to be grounded. The installer should have known that.

In New York State, the cable companies, got regulations adopted to require that the fiber optic dopped to be grounded. They wanted to drive u the cost of installation. |

These are aerial drop wires, not UG. It is the connector on the side of the house that is grounded, not the glass fiber. I've heard rumors supporting the message prior to this but I could not verify it (but I believe it). |

Its the messenger in the drop that needs grounding for prevention from traveling and induced current. Same reason we bond figure 8 fiber trunk on aerials at every splice, more out of protection of anyone that gets into it at an inopportune moment than to save any equipment, as everything attaching to it is optical.
Plus on drops the steel messenger figure 8 is cheaper than the Kevlar coated stuff that is self supporting,  Hence why you probably heard about bonding the drop. |
