摘要

This study presents a novel hybrid access network for 60-GHz wireless and wireline applications using a frequency quadrupling technique. Both 1.2-Gb/s eight phase-shift keying and 1.25-Gb/s quadruple phase-shift keying radio-frequency (RF) signals for radio-over-fiber (RoF) links are demonstrated. A 1.25-Gb/s baseband (BB) on–off keying (OOK) signal for fiber-to-the- $x$ services is simultaneously generated and transmitted using the same modulator. The proposed system does not suffer from RF fading and needs no narrowband optical filter at the remote node to separate the RF and BB signals. A frequency quadrupling method for RoF link is realized to reduce the bandwidth requirement of the transmitter. Following 25-km single-mode fiber transmission, the observed receiving power penalty is negligible for both RF and BB signals. Wavelength reuse for a 1.25-Gb/s OOK signal via a reflective semiconductor optical amplifier for uplink transmission is also demonstrated.
