Exploitable results Thale AV result 1 Thales Avioncs proposed two possible configurations and aircraft targets for a MOTIFES compliant IFE system. These architectures use Plastic Optical Fibre and IEEE 1394 technologies as support for the distribution network. Such architectures have been designed to address the need of IFE systems on medium haul (single aisle) and long-range haul (twin aisle). This simple solution is able to solve several airplanes configurations. The commercial benefit is a new full digital IFE system with enhanced entertainment functions. Its design will provide to Thales Avionics and its partners advantages on its concurrence. Its architecture will provide high bandwidth, less weight than an existent IFE system, a full digital system, a lower maintenance, a more flexible installation and no EMI. Moreover, the proposed system enables to integrate COTS technologies and products. As an example of commercial target, the A380 will use optical fibber as the backbone of the distribution network. POF may be used because POF solves the major problems of EMI and installation. A potential option of our IFE system is the combination with a video surveillance system based on COTS SOCIAL BENEFITS: The development of a new IFE system standard based on POF should favour the Development of POF industry in Europe. Furthermore, such an innovative solution will bring a competitive advantage to the IFE industry in Europe, thus leading to develop the employment. Less weight means lower power consumption, which makes this system an environmental friendly one. SCIENTIFIC BENEFITS: Better network throughput available at the seat using new POF technologies. Thales RT Result 1 Two types of POF transceivers dedicated to IEEE 1394 and avionic datacom applications have been designed and prototyped. The first one is based on a VCSEL from Honeywell and operates at 850 nm on Lucina fibre from Nexans. The second one is based on the 650nm VCSEL developed by the Firecomms and is compatible with 1 mm Eska Mega Fibre from Mitsubishi (cabled by Nexans). The packaging of both transceivers is inspired from the Small Form Factor (SFF) multi source agreement. 850 nm transceivers operate from -40°C to +85°C thanks to a patent enabling the regulation of the output optical power of the VCSELs. The new temperature regulation process provides degradation less than 1 dB over -40°C to +85°C. Using the new ELIO optical contact for severe environment developed by Souriau (previously FCI), the 650-nm transceiver is the first connectorized POF module compliant with avionics requirements in terms of vibration. Regulation needs to be improved, thanks to better appropriate drivers. Since, minimizing cost and power consumption were two of the main targets of Motifes transceivers, Automotive manufacturers could potentially be interested by such products. For the moment, D-Lightsys, spin-off of Thales Research and Technology is in contact with avionics manufacturer for a futur integration of their products in aircraft systems. NMRC result 1 Over the course of the MOTIFES project the NMRC has added expertise concerning the design, fabrication and characterisation of red VCSELs and associated technologies. It is the intention of the NMRC to make available, at commercial rates, this expertise to third parties. Obviously, the most likely exploitation route is with current MOTIFES partners, especially the 'start-up' partner, Firecomms, and the Thales 'spin-off' D-lightsys. We intend to provide the following services for visible VCSEL technology: 1: Feasability Studies and consultancy 2: Design and simulation 3: Fabrication and packaging 4: Environmental testing 5: Lifetime testing 6: Failure analysis 7: Prototyping 8: Low volume production NEXAN result 1 Nexans is the worldwide leader in the cable industry. The Group brings an extensive range of advanced copper and optical cable solutions to the infrastructure, industry and building markets. Nexans cables and cabling systems can be found in every area of peoples lives, from telecommunications and energy networks, to aeronautics, aerospace, automobile, railways, building, petrochemical, medical applications, etc. With an industrial presence in 29 countries and commercial activities in 65 countries, Nexans employs 17,000 people and had sales in 2003 of euros 4 billion. Our competence Centre in Lyon is developing and manufacturing Polymer Optical fibber P.O.F.). This new fibber was originally designed for Local Area Network ( L.A.N.) inside building and present bandwidth characteristics close to silica , so it would be interested in switching silica fibber by POF to verify these performances. Nexans Draveil is mainly working for aerospace market and specially for Airbus one. We have developed and we are manufacturing optical cables for on-board equipment as ABS 0963-003 LF. As this cable fulfil completely Airbus specification we evaluated this cable versus two new cables developed within Motifes: Study 132666 with PMMA step index 1000µm fiber and Study 132667 with gradient index Cytop fibber 120/230/500 µm. Main conclusions are for step index cable: - Working temperature : - 55 + 105°C / 3000 Hours - < 200 dB/km , > 15 MHz.km - low variation of optical attenuation during temperature cycles - low sensivity to tight bend radius - easy to connect - fire / smokes / toxicity in accordance with aerospace regulations Other conclusions are for gradient index cable : - Working temperature : - 55 + 70°C / 7000 Hours - < 35 dB/km , > 400 MHz.km ( close or better than silica ) - low variation of optical attenuation during temperature cycles - easy to connect (Nexans design and produce connector , easy to handle - withut glue and crimping )%l - fire / smokes / toxicity in accordance with aerospace regulations Final conclusions could be: - for multimedia purpose inside aircraft - Gradient index cable could be used for backbone - because of high bandwidth - Step index cable could be used for links between backbone and seats Gradient index originally designed for building has to be enhance specially for : - working temperature range - low sensivity to mechanical stresses. Firecomms result 1 Firecomms is an SME manufacturing optoelectronic data communication transceivers for automotive, aerospace and consumer networking applications based on plastic optical fibre (POF). Firecomms currently offers transceiver components to the auotomotive and consumer markets based on RCLED technology at speeds of up to 250 Mbps. The major result for Firecomms from the MOTIFES project is the development of visible VCSEL devices and transceiver modules that will enable Firecomms to address market opportunities at data rates in excess of 1 Gbps.
