Universitat Politècnica de Catalunya - UPC posted this:New FFTH-PON Network for extended numbers of usersA new Passive-Optical-Network (PON) for Fiber-To-The-Home (FTTH) services has been developed in the frame of the National Research Project TEYDE. While current FTTH networks as GPON and EPON can reach a maximum of 32-64 users, the proposed PON can serve more than 4000 users, thanks to a new device for distributing the signal among the users that intelligently recycles the noise generated by other elements of the network. Partners to further develop the device and/or to establish license agreements with technical cooperation are sought.
Universitat Politècnica de Catalunya - UPC posted this:New robust and reliable chromatic dispersion measurement systemNew chromatic dispersion measurement techniques have been developed to improve some weakness of current commercial analyzers. The technology based on detection of amplitude nulls allows a significant reduction of the cost and complexity. Partners to further develop the system and/or to establish commercial agreements with technical cooperation are sought.
Universitat Politècnica de Catalunya - UPC posted this:Efficient technology to reduce interference in passive optical networksA new method for reducing interference in passive optical networks has been developed and patented. The technology allows the use of low cost lasers whose wavelength does not to be pre-selected, and assures a high speed communication of hundreds of users. Partners to further develop the system and/ or to establish commercial agreements along with technical cooperation are sought.

Universitat Politècnica de Catalunya - UPC posted this:OPTICAL REMOTE NODE DEVICE AND SUPPORT EQUIPMENT FOR CONSTRUCTING AND EXTENDING FIBRE-OPTIC ACCESS NETWORKSThe Remote Node performs all-optical interfacing between a metropolitan ring and the access trees to the homes, thus enabling a transparent metro-access converged optical network. The device performs the functions of wavelength add&drop, ring protection and optical amplification with remote pumping. It is composed by a number of optical elements not requiring electrical power supply.

Consejo Superior de Investigaciones Científicas posted this:Scalable aperture-combined optical telescopeCSIC and the Astrohita Foundation have developed a telescope, which comprises several optical assemblies that focus the light from a target on individual optical fibers, which are combined together in a final single optical fiber. The rest of the light is simultaneously collected in image devices, which record the field of view of each optical assembly. The gathered images are summed together to achieve a high-quality final image. These telescopes are not of interest only in the field of astronomy but also in the tracking of satellites and space junk. Industrial partners from the Astronomy, Astrophysics and telecommunications sector are being sought to collaborate through a patent licence agreement.
Universidad de Alcalá-OTRI posted this:Sensor system for the detection of objects / obstacles in critical points of railway linesThe research group in Electronics Engineering Applied to Intelligent Spaces and Transport (GEINTRA) of the Department of Electronics of the University of Alcalá has developed a sensor device and its corresponding procedure to detect the presence of any type of objects (vehicles, people, animals, etc…) in points of interest of the railway route (level crossings, tunnels, etc.), sending to the train the visual information and corresponding warning signs. The device consists of a set of cameras located in the environment of each point of interest, an infrared lighting system, an image processing module and a wireless communication system with the train. The system contributes to the increase of safety in rail transport, providing the machinists with visual information about the state of the conflicting points and notifying the presence of obstacles. The system is capable of detecting the presence of objects in daylight and nighttime conditions. The group seeks for licensing agreements, technical cooperation agreements or commercial agreements with technical assistance, with companies that work in the manufacture of safety equipment for rail transport systems.
Universidad de Alcalá-OTRI posted this:System and method of distributed characterization of dispersion profile of an optical fiberThe Photonic Engineering research group of the University of Alcalá, in collaboration with the Institute of Optics of the CSIC and FOCUS S.L. presents a system and method of distributed characterization of optical fibers that provides an absolute measurement of the dispersion profile of the fiber. The group looks for telecommunications companies specialized in the industrial area of sensing and distributed fiber optic characterization, for patent licensing agreements or commercial agreements with technical assistance.
Universidad de Alcalá-OTRI posted this:Mode-Locked pulsed Laser using Saturable AbsorberThe research group in Photonic Engineering from Alcalá University, in collaboration with CSIC, offers a mode-locked pulsed laser whose optical resonator comprises a saturable absorber based on nitrides of group III. The use of this type of materials as saturable absorber allows to achieve a high stability and emission energy without increasing the complexity of the system. Its applications cover areas as diverse as medicine, industry, optical communications and scientific research. The group seeks for companies in these sectors to sign technical cooperation agreements, commercial agreements with technical assistance or patent licensing agreements.
