Paper Abstract

This paper describes the results of an experiment where an FSO link was established between a ground terminal and an airborne terminal on a tethered aerostat. In the first part of the experiment, four 10 Gb/s WDM channels were transmitted from the aerostat to the ground terminal, demonstrating error-free performance over many 5 minute windows. In the second part of the experiment, both one and two WDM channels, each running at a native 40 Gb/s rate, were transmitted over the FSO link, demonstrating error free performance over short (30 second) timeframes, and bit error rates in the 10-6 range over longer term operation. During all tests, a 1 Gb/s optical Ethernet channel was run on a separate WDM channel. The paper will describe the test configuration as well as the results when running both single and multiple channels. The impact of the overall system design used for this experiment on the link integrity will be analyzed and discussed. It was found that the spatial dynamics of the aerostat as a function of time of day had an impact on the quality of the link - this will also be discussed. Modeling of potential penalty sources will also be discussed.
