Re: DC fiber cut: field report

[Paul Trotter <ptrotter () ny ubs com>]

Shoot one of the fibers with a TDR.  This will tell you how far away the
break is.  The carrier generally has maps of the route and they can pin
point the location within a close enough tolerence to find the break. 
We had a break in the street in Manhatten and we told the carrier how
far it was and it only took the a few minutes to locate it.
