Free space optics (FSO) system facilitates the transmission of message signals through the atmosphere, providing numerous advantages. In spite of this, the efficiency of FSO across long distances is restricted by the presence of a variety of cloud situations. This research examines the effectiveness of FSO module under various cloud conditions. It proposes a wavelength division multiplexing (WDM) methodology, combined with multiple-input multiple-output (MIMO) techniques. Furthermore, it utilizes homodyne detection in the receiver section. The suggested framework achieves transmission ranges under various cloud conditions: 108 m under cumulus clouds, 223 m under stratus clouds conditions, 330 m under stratocumulus clouds conditions, 140 m under altostratus clouds conditions, 160 m under nimbostratus clouds conditions, 130 km under cirrus clouds conditions, and 200 km under thin cirrus conditions. Performance assessment is a comprehensive examination of critical parameters such as Bit Error Rate (BER) and Q factor to fully evaluate system performance.

Active accounts were imported to the new platform and assigned a random password by default. In order to access your account you need to access the login page and go through the Lost Password dialog (involves the system sending you an email with instructions) in order to reset your password. This step is necessary as passwords are kept in hashed form and the new platform uses modern hashing algorithms incompatible with the previous ones.
