High-stability, high-signal-quality radio-over-fiber system for IEEE802.11ad packet transmission based on optical single-sideband modulation in W-band

Abstract

To address the communication needs of high-speed trains such as bullet trains, which require high-speed millimeter-wave wireless links, we developed a high-stability radio-over-fiber system to transmit IEEE802.11ad packets using optical single-sideband (SSB) modulation. The system comprises an optical SSB modulator with automatic bias control and a low-distortion millimeter-wave amplifier stage and is capable of generating and transmitting IEEE802.11ad packets with 16-QAM modulation under an error vector magnitude of 5.8% at frequency of 97.57 GHz over a 45.5-km-long single-mode fiber.
