Latest Patents

Princy Johnson holds a patent for a "Reconfigurable WDM mux/demux/OADM." This invention features a reconfigurable optical add-drop module that includes a coarse demultiplexer for outputting sub-bands of wavelengths, a fine mux/demux for adding and/or dropping wavelengths, and a coarse multiplexer for remultiplexing the sub-bands. An optical switch is integrated between the coarse demultiplexer and the fine mux/demux, allowing for the switching of sub-bands for pass-through or add/drop functionality. The reconfiguration process can be performed remotely and automatically, minimizing interruptions to traffic. By focusing on sub-bands rather than individual wavelengths, the invention reduces the number of switches required, thereby decreasing losses and space requirements. This innovation simplifies the upgrade process from pass-through to add/drop for one or more sub-bands, ultimately lowering the initial capital costs of nodes and the expenses associated with upgrades.
