    Description

    COST Action 270 ("Reliability of optical components and devices in communications networks and systems"):
    At the first Inaugural Meeting (December 2000) in Brussels two workgroups were established.
    Workgroup 1 (WG1); Reliability of Optical Networks and Systems including Free Space Laser Communication:
    Objectives
    - develop models to estimate survivability of optical networks,
    - cost studies for different survivability strategies,
    - network optimization from reliability and cost point of view,
    - defining the weak points in the network regarding components and systems (input for WG2),
    - collecting reliability data for components from suppliers and WG2,
    - defining the reliability requirement of components for optical,
    - networks (input for WG2)
    Workgroup 2 (WG2); Reliability of passive components e.g. jumper cables, fiber coatings etc. including high optical power application and irradiation effects:
    Objectives:
    - reliability tests: test methods and relevant test series,
    - Round Robin on certain components,
    - acceleration factors,
    - standards,
    - high optical power effects in all passive components,
    - irradiation effects,
    - weak spots (failure mechanisms),
    - service environments, standards,
    - field data of components.
    - life time estimation methods
    In June 2003 was a short term scientific mission from a PhD-Student from France Telecom to Graz. In this measurement and simulation campaign "Free Space Optics" (FSO)-systems were investigated in regard to dense fog. The action will be finished in June 2006.
