Re: Redundant Power

A friend of mine operates an excavator. He's doing a one mile long project right now with an $85,000 penalty for cutting a fiber line. The Fiber owners are working side by side to make sure this doesn't happen. Last week while scanning for the fiber optic the owner 'sees' the fiber only 6 inches below his scan tool. He doesn't believe but he hand digs anyway and one shovel deep, there is the fiber! It was supposed to be more like 40 inches down. It was directionally bored, not trenched in, so it goes up and down and all around depending on how hard the ground was where the boring tool went. And we wonder why fiber cuts happen!

There is always some single point of failure, some times even beyond
your control.  Such as all of our circuits go through the same local
phone company switch.  A fiber cut a couple of years ago brought down
everything leaving our local city.  All voice, frame relay, and
internet, no matter who the carrier was.
Even our PTP leased lines went away.  All due to a back hoe digging on
the wrong side of the markings for the underground cables.
