DWDM INCREMENTAL GROWTH
DWDM has a unique feature of
incremental growth whereby it is not required to make the complete
investment once. A DWDM infrastructure can deliver the necessary
capacity expansion, laying a foundation based on this technology
is viewed as the best place to start. By taking incremental
growth steps with DWDM, it is possible for service providers
to reduce their initial costs significantly while deploying
the network infrastructure that will serve them in the long
run.
Their modular architecture supports a "pay-as-you-grow" approach
that allows an incremental growth of the system capacity whenever
the need arises. Consequently service providers can plan network
investments in step with their traffic growth.
