CESNET Showcases its Disaggregated Open Optical Line System at the Optical Fiber Conference 2020

San Diego March 10th, 2020. CESNET presents its disaggregated Czech Light open optical transmission system at the Optical Fiber Conference 2020 in San Diego. OFC is the world’s most important meeting in the field of optical telecommunications.
CESNET’s Jan Kundrát has prepared a demonstration called Physical-Layer Awareness: GNPy and ONOS for End-to-End Circuits in Disaggregated Networks, which is part of the scientific section of the conference. The demo shows how to use open source software and open hardware in telecommunication networks. The results of a project in which CESNET cooperates with Telecom Infra Project (TIP) and Open Networking Foundation (ONF) will be presented. The Czech Light OLS ROADM devices developed by CESNET as part of the project will then be presented at the show floor.
The demo, which uses TIP GNPy software and ONOS-based SDN controller ONOS, demonstrates optical network control including disaggregated transponders (Cassini, open hardware). The presentation combines multi-vendor hardware support in the ONOS SDN controller and simulation of optical path parameters in GNPy. It will demonstrate how a combination of open-source software and open hardware allows you to securely manage optical networks without relying on a single vendor, while maintaining the required quality of service and fast and flexible network management.
CESNET is intensively involved in open and disaggregated line systems for the transmission of flexible spectral services, including high-speed data, and the services of ultra-stable quantities and physical quantities. Details can be found in articles in leading scientific journals such as Journal of Lightwave Technology, or Journal of Optical Communication Networks, or on the CzechLight OLS product page.

The CESNET Association was founded by various Czech universities and the Czech Academy of Sciences in 1996. It is engaged in research and development in the field of information and communication technologies and builds and develops the CESNET national e-infrastructure for research and education. Thanks to its research activities and accomplishments, it represents the Czech Republic in important international projects, particularly in building the pan-European GÉANT data network and grid projects (EGI.eu), and actively participates in their implementation. The Association also works on the use of high-speed networks for sharing multimedia data both through synchronous video conferencing and shared applications as well as asynchronous streaming.
