An optical transponder aggregator includes a plurality of photonic switch cells (120, 220) configured to collectively implement switching functions for either an add transponder aggregator (200) or a drop transponder aggregator (100), a plurality of tap-monitors (122, 124, 222, 224) for control of the photonic switch cell s (120, 220); and a controller (150, 250) configured to change control roles of the tap-monitor s (122, 124, 222, 224), depending on whether the plurality of photonic switch cells (120, 220) collectively implements switching functions for the add transponder aggregator (200) or for the drop transponder aggregator (100). |
