    POF - Polymer Optical Fiber

    Carrying out investigations to increase the bit rate and bridgeable distance lengths for data transmission via POF as part of the collaboration on the "POF-ALL" project, see http://www.ist-pof-all.org. Some of the most important results of the "POF-ALL" project as well as an outlook on a follow-up project can be found in the article "Polymer fibers in Bavaria and Europe", Magazin Technik in Bayern 3/2008, Verlag Neuer Merkur GmbH, Munich, see http://www.technik-in-bayern.de.

    In the 90s, assembly work on POF and PCF (simplex and duplex cables, various connector types and processing methods).
