Experience with Plastic Optical Fibres

POF – Polymere Optical Fibres

Some of the most important results of the “POF-ALL” project as well as an outlook on a follow-up project are being presented in the article “Polymerfasern in Bayern und Europa”, Technik in Bayern magazine 3/2008, Publishers: Neuer Merkur GmbH, Munich( http://www.technik-in-bayern.de).

  • In the 90s Connector mounting on POF and PCF (Simplex- and Duplex cable, various connector types and handling methods)
  • Design and fabrication of a connector mounting tool for POF (HotPlate), Distribution by “Leoni” (http://www.leoni.com)
  • Design and fabrication of a POF attenuation meter
  • Design and fabrication of various interface converters, e.g. RS232 (with self powered option), RS485 for POF
  • Design and fabrication of multiplexers for the transmission over PCF fibers
  • Test runs to increase the bit-rate and achievable distances for data transmission via POF as part of our input for the “POF-ALL” project (see www.ist-pof-all.org. for details)
