International Transactions on Electrical Energy Systems, Volume 2023, Issue 1, 2023., 2023 Energy efficiency in optical networks is one of the important criteria to attain enhanced performance. Better energy efficiency can be attained in optical networks if the resources are properly scheduled. Polling sequences perform resource scheduling based on load requirements, and various methodologies have evolved in recent times for better ...

IET Communications, Volume 16, Issue 8, Page 902-914, May 2022., 2022 Abstract With the increasing number of fibre access users, P2P file sharing download traffic has gradually become one of the enormous bandwidth consumptions for the access network. Localizing traffic could save bandwidth and reduce latency, but it caused optical line terminal (OLT) overload problems.

Wavelength and Bandwidth Allocation for Mobile Fronthaul in TWDM-PON [PDF]
IEEE Transactions on Communications, 2019 Time- and wavelength- division multiplexed passive optical network (TWDM-PON) has attracted considerable attention for the next generation optical access systems. Among potential applications of TWDM-PON, a major application is the support of mobile fronthaul streams between radio units (RUs) and distributed units (DUs) in the centralized radio access ...
