Abstract

The efficient mitigation of crosstalk-induced “error floor” in system performance by using soft-decoding LDPC codes in an OAM-based four modes multiplexed fiber transmission system is experimentally demonstrated. A significant coding gain of >15.5 dB is achieved, depending on the amount of crosstalk from other channels.
