Abstract :
A dense wavelength-division-multiplexing (DWDM)-based frequency-interleaved optical distributing system merging wired and wireless services is proposed and experimentally demonstrated. In the proposed scheme, two channels of baseband signals for wired applications and two channels of 62.5-GHz radio-over-fiber signals for wireless applications with a data rate of 1.25 Gb/s share a single 100-GHz DWDM grid to increase the spectral efficiency. The signals are distributed over 40-km single-mode fiber without any compensation and only a power penalty of less than 0.5 dB is observed. Optical demultiplexers based on fiber Bragg gratings are used to select corresponding frequency components at access points.
