2002 - cesnet

Park Property Trust, a.s. We have a map of the lines and their parameters, accordingto which we are able to set up a testing loop, as necessary.We have also evaluated the possibilities of 10GE transmission over a distanceof up to 800 km. Based on theoretical analysis, we simulated this line and presentedour results during a subsequent meeting of researchers.In addition, we focused on the possibility of deployment of optical switches inthe optical infrastructure of CESNET. We explored the availability and pricesof individual components and compared the prices of the system based onWDM and CWDM technologies. In November, we carried out measurementsat a WDM multiplexor of 1,330/1,550 nm. These measurements served for thedemonstrative verification of a single-fibre transmission within the access networks.We made an inquiry for the price, availability and possible collaborationin the deployment of an optical switch in the testing section of the CESNET network,and distributed this inquiry to the selected manufacturers. We are nowevaluating their replies.62 High-speed National Research Network and its New Applications 2002
