For the generation of the maximum number of tones with a high tone to noise ratio (TNR) and the lowest amplitude difference (AD), different optical multi carrier-generation (OMCG) configurations are investigated in presented work by incorporating amplitude modulators (AM), dual drive Mach-Zehnder modulators (DD-MZM), and phase modulators (PM). Three modulators are employed in each OMCG, and a total of twelve different arrangements are investigated, such as (i) AM-DD-MZM1,2, (ii) AM-DD-MZM-AM, (iii) PM-DD-MZM1,2, (iv) PM-DD-MZM-PM, (v) AM-DD-MZM-PM, (vi) PM-DD-MZMAM in serial and (i) AM||DD-MZM1,2, (ii) AM||DD-MZM||AM, (iii) PM||DD-MZM1,2, (iv) PM||DD-MZM||PM, (v) AM||DDMZM||PM, and (vi) PM||DD-MZM||AM in parallel. A single RF source is deployed in all the OMCG configurations, and no other fiber Bragg gratings (FBGs) or tailored methods are incorporated. Further, an asymmetrical ultra-dense high-capacity 70 km bi-directional Radio over fiber (RoF) system is presented by incorporating the proposed OMCG and transmitter diversity supporting 10 GHz RF signal.

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.
