We propose and experimentally demonstrate a fiber‐wireless integration system at W‐band (75–100 GHz), and 80‐Gbps polarization division multiplexing 16‐ary quadrature amplitude modulation (QAM) signal is transmitted in an optical‐wireless‐optical system for the first time. After 50‐km single‐mode fiber‐28 (single‐mode fiber (SMF)‐28) transmission, the millimeter‐wave signal at 84‐GHz is delivered over a 4‐m 2 × 2 multiple‐input multiple‐output wireless link, and finally up‐converted to optical signal for another 50‐km SMF‐28 transmission. With the optical signal‐to‐noise ratio of 30 dB, the bit error rate is below the forward‐error‐correction threshold of 3.8 × 10 −3 using cascaded multimodulus algorithm equalization at the receiver. The experimental results indicate that high‐order QAM signal can be well suitable for long‐haul large‐capacity optical‐wireless‐optical transmission in the proposed system. © 2015 Wiley Periodicals, Inc.
