and to add, OTDR at several wavelengths, just in case you want to do
xWDM in the future.

In my experience in leasing dark fiber strands over long distance the
providers usually give the option for regen colo space. And in some
cases they wanted to know full specs of the equipment you are going to
be using so there is no questions if it will work or not.
