Radio over Fiber (RoF) systems supporting high frequency millimeter waves have emerged as a great choice for the Fifth generation (5G) broadband communication. In this research article, a RoF system has been proposed with the integration of Wavelength Division Multiplexing (WDM) over 100 km single mode fiber (SMF) with Four Wave Mixing (FWM) suppression. Optical phase conjugation (OPC) and Band pass optical filter (BPF) based technique has been employed to suppress the FWM idlers. The results of the proposed WDM-RoF system have been evaluated at different input parameters such as input power, WDM channel spacing and the number of channels in the terms of output power, FWM, Q factor and Bit error rate (BER). A detailed comparison of Dispersion compensation fiber (DCF)-BPF and the proposed OPC-BPF has been performed. The results reveal the mid-link spectrum inversion in OPC-BPF helps achieve improved performance with enhanced FWM suppression and support for high input powers in the proposed system.

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.
