Avionic WDM LAN node utilizing wavelength conversion

A wavelength-routed WDM node was demonstrated to allow error-free transmission of digital optical signals between 4 inputs and outputs at all tested data rates. Even with the addition of 29.4 dB loss, data transmission through the node remained below 10e-12 at the target data rates of 1.25 and 2.5 Gbps. Though developed to support the cross-cube topology, this node is flexible enough to work within other network architectures, including ring, bus, or additional mesh topologies.
