This paper reviews various energy efficient approaches in existence and proposes a Hybrid
WDM–TDM PON architecture that allows the adaptive bandwidth allocation mechanism to …

Cost effectiveness and energy efficiency have recently become two practical issues during
access networks construction and operation. In this paper, we extend our previous proposal …

One of the main challenges of Passive Optical Networks (PONs) is the resource (bandwidth
and wavelength) management. Since it has been shown that access networks consume a …

A flexible hybrid wavelength division multiplexing-time division multiplexing passive optical
network architecture that allows dual rate signals to be sent at 1 and 10 Gbps to each optical …

Even if Passive Optical Networks (PONs) have proven to be more energy-efficient that other
access solutions, energy consumption minimization is becoming an important research …

In time division, multiple access (TDMA)-based passive optical network (PONs), a dynamic
bandwidth assignment (DBA) is necessary for efficient utilization of the available bandwidth …

This paper proposes a resilient, bandwidth scalable and energy efficient WDM–TDM
passive optical network (PON) architecture that provides network access services to the end …

Time and wavelength division multiplexed passive optical network (TWDM-PON) standards
dramatically increase the performance of PON systems and address ever-increasing …

Access networks must further advance to address the intensification of the requirements of
growing speeds and the usage of Internet applications, and time and wavelength division …

In order to reduce the cost for delivering the ever increasing broadband services, network
providers need to simplify their network architectures and have a better control of the …
