Abstract
The paper experimentally investigates the performance of the Ethernet and
Fast-Ethernet free space optical (FSO) communications link under the influence of the
weak atmospheric turbulence. A dedicated experimental indoor atmospheric chamber is used
to generate and control the turbulence conditions that affect the FSO link performance.
The chamber is calibrated and the measured data are verified with the theoretical
prediction. We also demonstrate methods to control the turbulence levels and determine
the equivalence between the indoor and outdoor FSO links. It is also observed that the
connectivity of Ethernet and Fast-Ethernet links are highly sensitive to atmospheric
conditions.
