Abstract :
A high-capacity coherent ultradense wavelength-division multiplexing passive optical network integrated with a 60-GHz radio-over-fiber system has been designed and experimentally demonstrated for the first time. In this proposed architecture, millimeter-wave signal generation is achieved by coherent technology, in place of the optical carrier suppression technique, which requires modulators with large bandwidth and precise optical interleavers. The system fully exploits advantages of coherent access networks to provide both multigigabit wired and wireless access services with high spectral and power efficiencies. Successful wireless transmission of multichannel 3.3-Gb/s quadrature phase-shift keying signals with 10-GHz channel spacing over 50-km single-mode fiber (SMF-28) has been achieved.
