was adjusted through three control iterations before moving sequentially to the
next ROADM. The resulting tilt error is shown after all three ROADMs have
been adjusted. After just two adjustments around the loop, the tilt error is
negligible.
The use of node-sequenced channel power tuning avoids instabil ities due to
competing channel power adjustments. Sequencing through all nodes in a net-
