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=20
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?
