Recent IEEE and ITU-T standards for time division multiplexing-passive optical networks
(TDM-PONs) with sleep mode recommend that the optical line terminal (OLT) in a TDM-PON …

In order to minimize energy consumption in Time Division Multiplexing-Passive Optical
Network (TDM-PON), IEEE and ITU-T have mandated sleep mode mechanism for Optical …

With the increasing concern over the energy expenditure due to rapid ICT expansion and
growth of Internet traffic volume, there is a growing trend towards developing energy-efficient …

This paper investigates different sleep mode mechanisms in ONUs and OLTs for point-to-
point (PtP) optical access networks and time-division multiplexed passive optical networks …

In this paper, a dynamic wavelength and bandwidth allocation with only Tuning ONU
Buffering (DWBA-TOB) scheme and an OSU-ONU Synchronous Cyclic Sleep (OOCS) sleep …

We report the power-saving effectiveness of an optical network unit (ONU) sleep technique
by performing numerical calculations using an ONU sleep simulator that we developed …

As the energy consumption of data communications networks and associated
telecommunications devices has been increasing rapidly, improving the energy efficiency …

Passive Optical Networks (PONs) are widely adopted as the last-mile technology due to the
large bandwidth capacity it provides to end users. In addition, PON is viewed as a green …

A TDM Passive Optical Network (TDM-PON) proposes the use of sleep modes for Optical
Network Units (ONUs) to maximize Energy Efficiency (EE). When an ONU manages a sleep …

Owing to environmental concerns, reducing energy consumption of optical access networks
has become an important problem for network designers. This paper focuses on reducing …
