1. A Reconfigurable Optical Add/Drop Multiplexer (ROADM) comprising:
at least one degree component;
at least one add/drop component, wherein the at least one degree component and the at least one add/drop component are in a disaggregated configuration;
a plurality of fibers interconnecting the at least one degree component and/or the at least one add/drop component; and
a controller configured to
responsive to any of ongoing operation and connection of one or more fibers of the plurality of fibers, cause a Connection Validation (CV) scan in the ROADM that cycles through the one or more fibers and that utilizes one or more of a plurality of techniques to obtain a reduced cycle time for the CV scan, and
determine one or more of connectivity and whether fiber loss is within expectations, based on the CV scan.
