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

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 ...
