First of all, there is no classic CO around here. There are fiber to
copper to serve small neighborhoods. As usual, you have your head up
your ass, because Verison doesn't provide any service in this area.



Let's see. Verizon only started to install FIOS a few years ago.


Another _wierd_tom_ straw man.


Most every wire connecting to the CO is copper.


Bull***. It used to be. They were even even stretched between
wooden things called 'poles', way back in ancient history.

And for 100 years,
direct lightning strikes to that copper resulted in no damage when a
protector was properly earthed where it enter the building. Michael A
Terrell does not deny this reality.


I deny that Verison or their FIOS is anywhere near my part of
Florida. Not that you know the difference between the various baby
bells.


FCC Part 68 requires this properly earthed protector at both ends of
a phone line. What makes a protector so effective?


Absolutely nothing. The so called 'protectors' are routinely blown
off the sides of houses and out of pedestals in Florida. If you knew
even 1% of what you claim to, you would admit the truth. I have seen the
required ground wire melted after a protector was vaporized.


A protector is
only as effective as its earth ground.. No protector stops, blocks,
or absorbs the typically destructive surge. A protector that earths
before those surges can enter a building means protection inside a
modem is not overwhelmed. That was known even 100 years ago.


Sure it was, and it's been known for decades that you are an ignorant
troll. No one disputed your little snippets of 100 year old half truths.


Two 'top of the front page' articles in Electrical Engineering Times
define what provides protection in "Protecting Electrical Devices from
Lightning Transients". Not a protector circuit. Protection is only
as effective as its earth ground and connection to earth ground. How
curious. Even FCC Part 68 requires a shorter connection to earth -
contradicting what Michael posts.


Lair. You are trying to put your foul lies in my mouth again.


Tell me again how you connect fiber optic cables to your mythical
lightning arrestor, tommy.


mpm - more could be learned. Not yet posted because engineering
questions are not being asked.


Why bother with engineering questions when you don't understand the
electrical characteristics of a piece of wire?


Makes little difference whether underground or overhead (Michael
ignores this reality only to argue).


That is pure bull***, and you know it. A buried cable has a better
chance of survival from a nearby lightning strike. If you don't
understand that simple concept, you are too stupid to keep wasting
oxygen, and should report to AL Gore for him to correct your CO2
problems.

I have only seen overhead cables installed as temporary repairs in
the last 20 years. This area started the conversion to fiber over 25
years ago. As usual, you have your head up your ass.


Same protection was required as
has been routine in telcos for 100 years to avoid surge damage.


Dumb ***. Lightning does not travel miles to a nonexistent
traditional Central Office. Get your head out of the '70s and see what
is being used these days. This subdivision is less than a mile from
where everything is converted to fiber. You are so out of date you have
no idea how it works, or that the conversion was done because of
constant repairs to Telco C.O. equipment from lightning damage, along
with vaporized pairs in the underground cable. Most of that was over six
feet deep in the downtown areas. You have no concept of reality, yet you
continue to run your ignorant mouth. The last of the fiber conversion
was done to add DSL capability to outlying areas.
