Optical wireless integration based on phase modulator down-conversion for W-band QPSK signal delivery

We demonstrate one optical wireless integration system for 44 Gb/s polarization division multiplexing quadrature phase shift keying (PDM-QPSK) signal down-conversion based on phase modulators. 2×100 km single-mode fiber-28 (SMF-28) fiber transmission and 3 m wireless delivery at 88 GHz W-band are realized in our experiment. We also compare the different modulation formats with the same bit rate transmission in this optical wireless integration link.
