Acreo runs several R&D projects related to signal transmission in optical networks and systems. Our research projects cover both fundamental physical phenomena and practical system applications. We have a complete transmission test set-up for 40 Gbps DWDM system experiments, characterization of EDFAs, SOAs and Raman amplifiers, as well as simulation tools for modeling of DWDM systems.
Competence
Acreo´s scientists and engineers have long experience from leading research laboratories and companies in Sweden and abroad. Our broad expertise in optical transmission and networking is internationally acknowledged.
Services
We can help you with design, simulation, laboratory and field tests of DWDM systems, EDFAs, SOAs and Raman amplifiers as well as high level system integration. Contact us and find out what we can do for you.
Fields of activity
- 10-160 Gbps transmission
- dynamic dispersion compensation
- modulation formats
- optical amplifiers in C-, L-, S-bands
- xDFA, Raman, SOA, LOA
- non-linear effects: XPM, SPM, FWM
- dispersion management and solitons
Modeling
Our expertise in numerical modeling of optical fiber transmission with emphasis on WDM, high bit-rates and ultra long-haul is based on key knowledge of component physics and mathematical and numerical techniques related to WDM transmission (BER) models. Field trials of operating systems in real working conditions and numerous laboratory experiments effectively complement our theoretical capabilities.
Technical Example
One example of our internationally acknowledged achievements is a novel EDFA gain control system: A combination of an electronic feed-forward and optical feedback control scheme enabled a considerable improvement of transient gain dynamics. The results were published in a number of journals and conferences.
