Orthogonal Frequency Division/Mode Division Multiplexing IM-DD Multimode Fiber Transmission System Based on Photonic Lanterns
A orthogonal frequency division multiplexing(OFDM)/mode division multiplexing multimode fiber transmission system based on photonic lanterns(PL) is proposed. Two mode selective PLs are used as multiplexer(MUX) and demultiplexer(DEMUX). LP01 mode and LP11b mode are selected as the transmission channels. An adaptive bit loading OFDM modulation is used to achieve the transmission of 7.2 Gb/s on a 50 m OM4 multimode fiber. The experimental results show that when the incident light power of LP01 mode is about 4 dB lower than that of LP11b mode, we can achieve the same received optical power by adjusting the polarization state of the two signals. When the received power is -13 dBm, the bit error rates(BERs) of two signals are 1.3×10 -3 and 3.2×10 -3, respectively, which are lower than the threshold of hard decision-forward error correction (HD-FEC). The system provides a solution for the large capacity data transmission with low cost at short distance.
