Low Loss Passive Optical Networks for Avionics
This paper introduces one kind IMA architecture based on passive optical network. The LOADNET project focuses on the realisation of cost-effective European photonic network technology for next generation, aircraft data communication systems and the exploitation of the huge investment made by the commercial telecomms and datacomms sectors in fibre-optic technology. Issues such as burst-mode detection in upstream PON scenarios, flexible rate allocation in downstream scenarios, and the simplification of hardware complexity at the optical network unit (ONU) side have. FTTH passive optical networks (PON) began with GPON, which for several years was used for lower bit rates (one gigabit and slower), then gradually evolved into a low-cost, well-proven technology, more recently resulting in XG-PON1 and XG-PON2 (allowing higher speeds). At present, high-blocking, large delay, and high insertion loss is the bottleneck of large-scale processor. This project is part of a study within the Advanced Air Transportation Technologies program undertaken at the NASA Glenn Research Center. Current and future advances in.
