Next-generation
reconfigurable optical networks that interconnect many
high-capacity media immersi-stations are expected to
accommodate fine-granularity traffic switching, shifting
complexity from electrical to optical equipment and
at the same time increasing throughput . A key operational
feature in such an optical network is the ability to
synchronize the switching node to the incoming different
data streams to facilitate efficient switching/routing
decisions. Synchronization should be achieved with accuracy
within a fraction of a bit time while using a minimum
number of preamble synchronization bits. Synchronization,
especially all-optical synchronization to allow for
the ever-increasing bandwidth requirements, is crucial
for preventing packet and information loss in switched
optical networks.
