Abstract

We have proposed a novel multi-band orthogonal frequency division multiplexing and passive optical network (OFDMA-PON) architecture using signal-to-signal beat interference cancellation receivers based on balanced detection at both the optical line terminal and the optical network units (ONUs). Simulation of the full-duplex system with 20 km SSMF transmission and a 1:4 split is achieved successfully. Without a laser source and amplifier at the ONU, our proposed multi-band OFDMA-PON system reduces the signal-to-signal beat interference simply and effectively, while the space of each band can be as small as 1 GHz and optimum carrier-to-signal power ratio at about 10 dB. Simulation results show that the OSNRs of the 40 Gb/s downstream and 30 Gb/s upstream transmission are only 20 and 16 dB required at $$\hbox {BER}=3.8 \times 10^{-3}$$ BER = 3.8 × 10 - 3 , respectively.
