In recent years, OFDMA-PON attracts attention as an optical access. OFDMA-PON can achieve high-speed communication and improve bandwidth efficiency. Because it is a combination of TDMA communication technology and OFDM communication technology, it is possible to dynamically assign OFDM subcarriers to different services on different time slots. Polarization multiplexing was proposed for OFDMA-PON However, during communication using orthogonal polarization, polarization rotation occurs due to external force applied to the optical fiber. Due to the polarization rotation, the orthogonal polarizations interfere with each other, so that BER becomes high. In this paper, independent component analysis is used to clarify the improvement of BER for this problem.
