Hi,

My colleague and I may be running a new dark fiber network in the Northeast.

We need an outsourced NOC to monitor for fiber cuts and serve as a contact point for customers.

Am I wrong in believing that there should be a way of lighting a single pair in the cable and then monitoring it for signal disruption? It is not a perfect solution, but arguably better than learning that the cable has been damaged from an irate customer.

Well that's easy - any halfway decent networking gear will detect when a link goes down, and reporting that to a monitoring system.  The hard part is locating the cable break, so you can fix it - not detecting it in the first place.

And... parenthetically, if a single link failure impacts customers, you're network is woefully badly designed.

Best to take any replies off the message board.

Probably best not to - a major point of this kind of list is to learn from each other.
