29 Piet Matthijsse graduated in Electrical Engineering at the Eindhoven University of Technology in 1971. After completing his PhD in Fourier Optics at Leuven University he worked on optical fibre and network technology at KPN Research and Philips Optical Fibre where he worked on PCVD fibre production product and process development. In 1991 Piet joined KPN Network Development and in 2001, Draka Comteq Optical Fibre. Louis-Anne de Montmorillon received his engineering diploma from the Institut d'Optique Graduate School in 1993, and a Ph.D. in Physics from the University of Paris-Sud in 1997. Since then, he has been working in the field of optical fibres for communications, first at Alcatel, then at Draka, and now at Prysmian Group in the Fibre R&D department in Douvrin, France. He has been involved in the design, development and deployment of new fibres for FTTx and long-haul applications. Louis-Anne has published over 50 papers and has been granted more than 50 patents. INSIGHT | Doing Business LOUIS-ANNE DE MONTMORILLON PIET MATTHIJSSE FROM THE BENDBRIGHT PATENT APPLICATION: “There is (…) a need for a transmission fibre with which it is possible to meet the criteria of the G.652 standard, i.e. which can be given commercial use in transmission systems of the FTTH or FTTC type, and which shows both reduced bending losses and reduced micro bending losses. In FTTH or FTTC applications, fibres are subjected to higher bending and micro bending stresses than in long-haul transmission applications. Indeed, in FTTH or FTTC applications, overlengths of fibres are generally wound in increasingly miniaturized storage boxes; moreover the fibre will be subject to significant bending stresses related to the environment of its installation.” PRYSMIAN GROUP EDITORIAL STAFF
