PERFORMANCE ANALYSIS OF ADAPTIVE BIT LOADING SIPM-OOFDM IN INTENSITY MODULATION AND DIRECT DETECTION TDM-AND TWDM-PON SYSTEMS

Abstract:

Technological advancements over recent decades prompted the development of bandwidth-intensive services, necessitating the deployment of optical fibers in access networks up to the subscriber. To address these increasing demands, innovative transmission techniques, including advanced modulations and architectures, are expected. This study aimed to enhance transmission distance and user capacity in Passive Optical Networks (PON). The Subcarrier Index Power Modulated Optical Orthogonal Frequency Division Multiplexing (SIPM-OOFDM) technique, which conveyed additional information per subcarrier compared to conventional OOFDM, was implemented using MATLAB R2019a. To further improve the capacity performance, an Adaptive Bit Loading SIPM-OOFDM (ABL-SIPM-OOFDM) was implemented. We have modeled an IM/DD link in Optisystem7 and simulated the performance of conventional …
