Project Details


The goal of this project is to investigate the most promising dispersion maps for optical transmission at data rates of 10 Gbit/s and higher for single channel and multi-channel operation. Distances from about 50 km to thousands of km are considered. Standard fibers, dispersion shifted fibers, true-wave fibers and dispersion compensating fibers are used in the project. The investigation is both numerical using state-of the-art commercial and proprietary optical network simulators and experimental using a fiber loop set-up.
In the EU ACTS project DEMON (Demonstrating Evolution of Metropolitan Optical Network) we have performed comprehensive numerical and experimental investigations of normalized sections for 10 Gbit/s optical transmission in optical ring networks in close cooperation with Deutsche Telekom and Virtual Photonics Inc. in Berlin.
In the STVF cooperation project “10 Gbit/s systems investigations of dispersion compensating fibers” together with Lucent Technologies Denmark dispersion compensating fibers are evaluated numerically and experimentally in a 10 Gbit/s systems context. The project supplements an ongoing Industrial Ph.D. project with Lucent Denmark.
In the STVF cooperation project “Systems simulations” together with Tellabs Denmark numerical simulations are performed of 2.5 and 10 Gbit/s long-distance unrepeated systems for one or several channels.
In the STVF project “Highly Nonlinear Fibers”, a collaboration between Lucent Technologies and COM, is concerned with aspects of nonlinear fibers that are also used in system experiments.
We have also obtained 4x10 Gbit/s bi-directional transmission over 88 km true-wave fiber using an in-line semiconductor optical amplifier.
