Complete flexibility provided by the ROADM unit highly simplifies the design of optical networks in
terms of unit placement. Flexibility provided by units per se, in any case, is not enough to
guarantee the possibility to define any possible optical path at the network level. The Cisco
Transport Planner optical design tool features the possibility to design DWDM networks based on
ROADM functionalities and to verify all the possible optical paths and the DWDM interface types
(fully flexible network design) defined by the user. Fully flexible network design resulting from the
joint selection of both optical paths and DWDM interface types is highly customizable by the user,
who has the possibility to compare different solutions and to create what-if scenarios in a simple
and effective way.
Figures 3 through 5 show a sample signal-flow diagram for a Cisco ONS 15454 MSTP ROADM
node, outlining the use for each unit type.
