[One of the continuing debates is whether R&E networks should purchase
wavelengths or dark fiber in the build out of their networks.  In metro
areas and on routes where there are few competitive suppliers dark fiber is
usually the better bet.  In the more competitive corridors where there is an
abundant supply of wavelengths it still remains an open question of which is
the better value proposition.  A lot depends on the expected number of
wavelengths that will be required for the lifetime of the network.

A consulting company Analsys has a done wonderful detailed analysis on the
pros and cons of dark fiber versus wavelengths for Ukerna, the UK R&E
network organization in their planning for their next generation network
SuperJANET5. Although every country has its own unique requirements this
document is well worth the reading to understand the many complex issues of
fiber versus wavelength ownership.

Their conclusion?  Fiber ownership is a far better value proposition. This
is especially true with the advent of the new low cost OEO and CWDM
wavelength technologies which significantly reduce the cost of deployment of
wavelengths.--BSA]
