The CO-OFDM system plays a critical role in managing the effects of polarization mode dispersion (PMD) in optical communications, providing opportunities to optimize performance, durability and polarization state capability. DSP digital compensation is crucial to maintain signal quality, reducing error vector magnitude (EVM) and binary error rate (BER). DSP optimizes transmission, adapts to changing conditions, compensates for chromatic dispersion (CD) and PMD without physical intervention, reducing costs and extending network reach. Using modulations such as 16-QAM and 4-QPSK at 100 Gbps, it is advantageous for data centers and inter-satellite communications. A Python-based DSP model has been proposed to mitigate these effects, significantly improving signal integrity and system performance with a binary error rate (BER)∼10−4.
