Labs - Optical Access and Local Area Network lab

ECO-Lab for Advanced Optical Access and Local Area Networks

Introduction

After having conquered the core and metropolitan networks, optical fiber is now penetrating into the access and local area networks. Its low loss and huge bandwidth enable the delivery of any current and foreseeable set of broadband services, and also make it a nice match to the wireless link to the end users. The aim is to come with converged network solutions enabling delivery of any broadband service to the end user/device, wire-bound as well as wireless. In this lab, we investigate optical routing techniques for delivering capacity-on-demand, for optimizing user mobility and network performance, and for reducing energy consumption. We explore techniques for flexible fibre-to-the-home (FTTH) networks, as well as optical in-building network solutions to extend FTTH’s huge capacity into the home. With radio-over fibre (silica or plastic) techniques, we create radio pico-cells for flexible high-capacity wireless coverage, while avoiding radio interference and significantly lowering radio emission levels. Free-space dynamically steered optical beam communication is investigated to offer the ultimate ultra-high capacity wireless communication.

Passive Optical Networks Lab

The PON Lab focuses on exploring flexible modulation formats and flexible clock rates to serve users according to their received signal performance.

Radio over Fibre Lab

The RoF Lab explores transmission techniques to deliver broadband wireless signals (mm-wave 20-90GHz) using silica single and multi-mode fibres.

Optical Wireless Communication Lab

The OWC Lab explores advanced optical transmission techniques to deliver wireless signals to mobile
devices using infrared pencil beams.

Plastic Optical Fibre Link Lab

The POF Lab explores home area networks employing plastic optical fibres to transmit wired and
wireless signals. Due to the narrow band of POF systems, advanced modulation techniques such as PAM
and DMT/OFDM are considered. Radio over POF using WiFi 2.4 and 5GHz and LTE/A is studies to create
a converged transmission solution for various in-home communication services.
