An upgrade at the physical layer regarding unbundling and dynamic bandwidth provisioning of a wavelength division multiplexed access network is presented. The capability of a reflective modulator to act as a photodetector is exploited and allows a tandem configuration to be used at the optical network unit (ONU) for flexible switching of the detection and modulation branch. Consequently, a mechanism...
We report for the first time transmission results of RoF WiMax OFDM-QAM IEEE 802.16d signals on one wavelength using REAM-SOA device. This device is demonstrated to be linear and does not disturb the RF signal.
