We have designed a novel radio-over-fiber configuration using an optical phase modulator along with optical filtering to generate an optical millimeter-wave for carrying downstream data and centralized lightwave for carrying upstream data. Since the remaining optical carrier with high power has been reused, the optical power is effectively utilized; therefore, the system cost can be reduced. We have calculated the power margin, and found that the margin is large even if no boosted erbium-doped fiber amplifier is used in the system. The eye diagrams and bit-error-rate performance at the receivers have been evaluated.
