DWDM, Long- and Ultra-long-haul
DWDM is the preferred solution to a majority of
service providers. It extends the life of the
existing fibers and reduces operational and
capital expenses by maximizing their
bandwidth capacity. DWDM solutions
also provide the mechanism to
integrate seamlessly and transport
TDM and SONET/SDH signals with
Gigabit Ethernet and SAN extension.
DWDM networks provide a true
transparent optical network.
