PSNC has been successfully implementing the construction of the PIONIER national fiber optic scientific network since 2001. Currently, PIONIER covers 6824 km of fibers in Poland and 2454 km in Europe, connecting all Polish academic environments, i.e. 21 municipal computer networks in 21 academic cities and 5 High-Performance Supercomputing centers. Within the framework of the PIONIER network, there have also been built cross-border fiber-optic connections with all scientific networks of neighboring countries and a large part of international scientific cooperation is realized thanks to these connections. Additionally, a node of the pan-European research network GÉANT has been built by PSNC and connected to the PIONIER network with a 100Gb/s connection.
