Abstract

We explore a new wavelength management for ultradense wavelength division multiplexing-passive optical network with randomly distributed optical network unit (ONU) wavelengths, controlled with limited thermal tunability. Static and dynamic wavelength assignment paradigms and heuristic assignment schemes for spectrum management are proposed, simulated, and compared. ONU acceptances in activation processes and ONU availability ratios up to 99.99% are obtained in standard environmental conditions.
