Development of Infrared Optical Links Using Perfluorinated Polymeric Optical Fibres

This paper reports preliminary researches of optical links based on perfluorinated (PF) polymeric optical fibres (POFs) using infrared light carrier and related components. An infrared datacom-type LED emitting at ~ 945 nm is characterized. Lensless LED-POF and POF-photodetector optical coupling was developed enabling the use of 20 m length of CYTOPTM PF-POF. Applications as ~1 km optical links and lownoise analogue transmissions of low-frequency radio signals (Wireless-over-Fibre – WoF) are firstly envisaged.
