The long-term throughput of optical links between a circular-LEO satellite and a ground station is assessed for systems with fixed and variable data rates. For a fixed data rate, we evaluate the minimum elevation angle above which the link should be established in order to maximize the throughput. The ratio of this optimized constant-data-rate throughput to the throughput of an adaptive transmission with a data rate proportional to the received power is found to depend mainly on the satellite altitude.
