Next generation passive optical networks provide a large amount of bandwidth but also
consumes a lot of power. The ONUs of such networks dominate a major portion of energy …

Reducing power consumption in an access network has become an increasingly imperative
design goal, due to the fact that information and telecommunication technologies contribute …

Passive optical networks (PONs) are a preferred technology for implementing fiber-to-the-
home networks. Though PONs minimize power consumption compared to digital subscriber …

This paper describes sleep and adaptive link rate (ALR) control functions to reduce the
power consumption of optical network units (ONUs) in 10? Gb∕ s Ethernet passive optical …

In order to minimize the energy consumption of Time and Wavelength Division Multiplexed
Passive Optical Networks (TWDM-PONs), an energy efficiency scheme was developed by …

An energy conserving TDM-PON architecture using sleep mode ONU is presented. Sleep
mode ONU with fast wake-up capability is demonstrated. The architecture employs novel …

In a 10-gigabit-capable passive optical network (XGPON) system, a power management
function such as cyclic sleep mode can be implemented to increase energy efficiency of an …

The energy consumption of communication networks is continuously growing. Many energy
saving approaches have been proposed at the device, system, and network level. The most …

In passive optical network (PON), in addition to efficient bandwidth management, a dynamic
bandwidth assignment (DBA) scheme can also enhance the energy efficiency performance …

In this paper we propose a scheme tailored for WDM-PONs, which employs dozing mode in
transceivers not only at the user side but also at the central office. The objective is to reduce …
