[IEEE 2018 41st International Conference on Telecommunications and Signal Processing (TSP) - Athens, Greece (2018.7.4-2018.7.6)] 2018 41st International Conference on Telecommunications and Signal Processing (TSP) - Field Trial of Alien Wavelengths on GARR Optical Network
摘要： At the Italian national level, GARR optical network is composed of two separate optical network domains. With the aim to integrate them we decided to use the alien wavelength technique. This is a hybrid solution based on the transmission and reception of optical signals, called alien wavelengths, that are transported on an infrastructure that is different from the one that generated them. We tested the technique first on a field trial, on two portions of our network of about 350 and 1200km long in order to measure the achievable performance. Based on the successful results we then implemented such technique on the production environment on about 3000km to deliver high-performance services. In this way we improved the overall efficiency of the Italian research and education network in a cost-effective way. This paper describes the overall activity, results and our experience in integrating the alien wavelengths in a production environment, with a special emphasis on deployment and operational issues.

Nanocomposite material that protects against laser attack
摘要： An international group of researchers has produced a new biologically based optical-nanocomposite material that helps protect against strong light. The material, which consists of biologically generated elemental tellurium nanocrystals as well as a polymer, could protect electronic devices from attack by high-intensity bursts of light, such as emitted by common lasers aimed at aircraft, drones, surveillance cameras and other equipment, and could also find applications in improving the capacity of high-speed optical networking.
