Abstract

Fixed grid is incapable of delivering and satisfying clients demands, as there is a massive increase in bandwidth demanded. To surmount this constraint, the terminology elastic optical network (EON) has been coined. Utilization and management of spectrum resources can be done effectively through EONs. EONs and their features are discussed, including super channel, the restoration squeeze scheme, and sliceable bandwidth variable transponders. The discussion also covered various modulation formats and transmissions like Nyquist wavelength division multiplexing (NWDM), orthogonal frequency division multiplexing (OFDM), and time frequency packing (TFP), followed by sliceable bandwidth variable transponder (SBVT) architectures.

Keywords
