摘要

In this letter, we propose and experimentally demonstrate a W-band (75-110 GHz) full-duplex transmission fiber-wireless-fiber system with the rate up to 60 Gb/s for the first time. Both the uplink and downlink in our proposed system consist of two spans of 80 km single-mode fiber-28 (SMF-28) and a 1-m wireless link. We experimentally demonstrate that our proposed system can simultaneously transmit a 60 Gb/s upstream quadrature-phase-shift-keying (QPSK) signal carried by 99 GHz carrier frequency over the uplink and a 60 Gb/s downstream QPSK signal carried by 101 GHz carrier frequency over the downlink. Both millimeter-wave generation and demodulation are enabled by photonic techniques. Wireless crosstalk that occurs between the uplink and the downlink is effectively avoided because the pair of antennas adopted in the uplink is polarization orthogonal to that adopted in the downlink. With the optical signal-to-noise ratio (OSNR) of 20 dB, the bit error ratios (BERs) for 60 Gb/s signal transmission are less than the third-generation forward-error-correction (FEC) limitation of 2 × 10-2.
