摘要

We propose a bidirectional transmission system based on stimulated Brillouin scattering effect and injection-locked distributed feedback laser to achieve an optical single-sideband modulation for downlink transmission. We reuse the transmitted light through phase modulation for uplink transmission to avoid interference of both signals in a bidirectional transport. After a 25-km single-mode fiber transmission is completed, a sideband power ratio of >15 dB is observed in the downlink transmission, and the power penalty of the system is <1 dB. In our proposed bidirectional transmission system, the performances of bit error rate analysis are good.
