A Multicast‐Traffic‐Oriented Energy‐Saving Algorithm with a Hybrid Sleep Mode for EPONs

Journal of Electrical and Computer Engineering, Volume 2016, Issue 1, 2016., 2016
High energy consumption in Ethernet Passive Optical Networks (EPONs) has caused intense research on energy‐saving methods in recent years. The most common method for EPON energy saving is to cause optical network units (ONUs) to sleep which are idle or low loaded.

Polarization diversity scheme for reach extension of WDM/TDM gigabit passive optical network up to 60 km using quantum dot semiconductor optical amplifiers

Доклады Белорусского государственного университета информатики и радиоэлектроники, 2021
Gigabit passive optical networks (GPON) are the most advanced technology. The data transfer rate is 2.5 Gbps for downstream and 1.25 Gbps for upstreams. But this network architecture has a limited physical network length of 20 km. This is due to the high

Identification of optical fibres in a passive optical network using highly temperature insensitive filters and reflectors

IET Optoelectronics, Volume 19, Issue 1, January/December 2025.
The authors demonstrate the use of highly temperature insensitive dense wavelength division multiplexing filters combined with optical reflectors and optical time domain reflectometry to uniquely identify specific optical fibres beyond the optical splitter in an optical access passive optical network (PON). The very low wavelength shift (∼0.1 pm/°C) of

Wavelength Tuning Free Transceiver Module in OLT Downstream Multicasting 4λ × 10 Gb/s TWDM‐PON System

Journal of Computer Networks and Communications, Volume 2014, Issue 1, 2014., 2014
We propose a new architecture of dynamic time‐wavelength division multiplexing‐passive optical network (TWDM‐PON) system that employs integrated all‐optical packet routing (AOPR) module using 4λ × 10 Gbps downstream signal to support 20 km fiber transmission. This module has been designed to support high speed L2 aggregation and routing in the physical

Network Design and Route Analysis Using Outside Plant

Journal of Engineering, Volume 2025, Issue 1, 2025.
Outside plant (OSP) is essential for telecommunications, internet, and other communication services that require connectivity beyond indoor spaces. These networks often involve the installation of cables, conduits, cabinets, poles, and other infrastructure elements to connect various locations.

Facing the Reality: Validation of Energy Saving Mechanisms on a Testbed

Journal of Electrical and Computer Engineering, Volume 2014, Issue 1, 2014., 2014
Two energy saving approaches, called Fixed Upper Fixed Lower (FUFL) and Dynamic Upper Fixed Lower (DUFL), switching off idle optical Gigabit Ethernet (GbE) interfaces during low traffic periods, have been implemented on a testbed. We show on a simple network scenario that energy can be saved using off‐the‐shelf equipment not explicitly designed for ...

Energy consumption of data transfer: Intensity indicators versus absolute estimates

Journal of Industrial Ecology, Volume 28, Issue 4, Page 996-1008, August 2024.
Abstract The assessment of energy consumption of data traffic for Internet services usually relies on energy intensity figures (in Wh/GB). In this paper, we argue against using these indicators for evaluating the evolution of energy consumption of data transmission induced by changes in Internet usage.
