Multifunctional operation of a fiber Bragg grating in a WDM/SCM radio over fiber distribution system

In this paper, we have demonstrated a hybrid wavelength division multiplexing/subcarrier multiplexing (WDM/SCM) based radio-over-fiber distribution system employing direct modulation of the laser transmitters followed by a Bragg filter at the receiver base station. This work shows that it may not be a necessity to generate single side band (SSB) at the transmitter in a radio/fiber system incorporating WDM technology, as optical filtering at the receiver base station may be used to overcome system limitations imposed by double side band (DSB) generation at the transmitter, in addition to optical channel selection.
