Free space optics (FSO) has regained considerable attention over the years due to higher data rate transmission capability and unlicensed bandwidths. Nevertheless, different atmospheric conditions result in the considerable deterioration of the performance of the link. The performance of MDM-WDM based FSO link has been analysed considering LP 00 and 01 modes employing AMI, NRZ and RZ modulation techniques. The system has been designed to transmit information at a data rate of 80 Gbps upto a transmission range of 6 kms under clear air conditions. The maximum transmission range under heavy fog and rain conditions reduces to 900 m and 950 m respectively.

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.
