The difference between Fuji and Cisco is the backplane
architecture. The former is redundant and is
a five nines solution. The latter is not and is a four
nines solution. You will find the cisco device cheaper 
to buy and operate. The cisco is also less RU and less
power.

If you haven't already lighted your own dark fiber
network, there's a lot to know at layer 1 to be sure
you get the redundancy you're looking for in layer 3.
Have you considered leasing circuits from a LEC or
buying a wavelength managed service?
