100 Gbit/s optical wireless communication system link throughput

Novel results on the link layer protocol performance of future infrared personal communication links at a line rate of 100 Gbit/s are presented. The discussion aims to demonstrate the shortcomings of the currently standardised half-duplex mode of communications in the physical layer and details its negative impact on the link layer efficiency. Results of a non-standardised full-duplex mode of operation that is however suitable for application in future high capacity infrared links are also presented. The results predict that the migration to this full-duplex mode can prove advantageous for the link layer performance, as it not only yields a higher efficiency, but also requires significantly smaller frame and window sizes.
