There is a middle ground between “not managing customer light” and “not managing anything” though. The Adva ALM 
solution that a few folks that have mentioned, along with others like Lucent SmartLGX, effectively bridge this gap by 
helping trace the precise location of cuts and even smaller scale incidents like microbends to expedite diagnosis and 
repair to the extent possible. It’s not a panacea and definitely not a substitute for managing the hardware at the 
endpoints, but it does improve operational responsiveness in a measurable way. And yes, there are dark fiber providers 
in the Northeast that leverage this technology, at least on some portion of their fiber plants.

Dude, it's dark fiber.

I for one, do _NOT_ in any shape or form, want my DF provider to put any equipment (monitoring, or otherwise) on 
strands I lease, period.  I just want
tubes in the ground, end of story.  This is certainly not an airplane and does not need a pilot.  It's passive tubes 
sitting on right of way and customer
is licensed to pass light thru that passive tube.  Everything else is extra, and I want no active service whatsoever 
(besides for power capacity at
regen plant colo).

If there is a disturbance event that creates LOS alarm on customer equipment, they will call in and open a ticket to 
begin troubleshooting.

Name me one dark fiber provider in northeast that (unless you buy their managed dark fiber solution) will monitor 
your fiber strands and the customer
light for you.  I can tell you, major fiber providers in northeast are all the same:  the customer is the monitoring 
system.  If fiber is down, customers
call in.  In fact, I can't recount how many times I've had dealing with a large fiber provider here (unnamed to 
protect the guilty) who also requests
and asks customers to shoot OTDR for them.

Generally speaking, dark fiber providers who also compete with their customers (e.g. fiber provider that sells lit 
services) have tendency to react
faster to certain fiber cuts on certain routes, if their backbone links are sitting in them.  But for specialty dark 
fiber providers who only sell dark,
it's not a bad idea to light one of the strands for internal continuity checks; but at worst case scenario, when a 
customer calls in to report an LOS
alarm and suspects fiber disturbance, that's usually enough information to start sending your crews out and begin 
taking traces.
