<p>without pilots... or a maintenance manager!</p>
<p>Speaking of which, seeing this kind of question, from a VP at a
company in the submarine cable business, would sure make me leery
of leasing fiber from them, if there's an alternative. Now, one
would not necessarily expect a VP of Business Development to know
all the details of network management - but seems to me that he's
basically advertising that he's learned about cable breaks from
irate customers, rather than being forewarned by his operations
team that "you're about to get a bunch of irate calls."<br>
<br>
Heck, back in the old days (I was at BBN designing network
management for the original Defense Data Network) - we knew how to
instrument our networks, and design for redundancy & diverse
routing. Boy did we have egg on our face when a backhoe took out
all the connectivity to the Northeast. We detected the outage
just fine - but we (and lots of other folks) were all caught short
to discover that AT&T Long Lines routed all of our "redundant"
circuits through the SAME fiber bundle. I expect there are others
here who remember that debacle.<br>

It sounds like you don’t have an experienced fiber optic network
engineer on the project yet. There is much more to facilities
monitoring then just checking for disruption. I recommend that you
either retain a consulting engineer or employ one during
development. I’m sure operators here are happy to share their
ideas, but you will need some expertise in fiber infrastructure to
make intelligent decisions about optics, wavelengths, in-band
versus out-of-band administration, and a slew of other topics.

starting an airline without pilots :-)<br>

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.
