Transparent Fiber–Radio–Fiber Bridge at 101 GHz using Optical Modulator and Direct Photonic Down-Conversion

We demonstrate the first fiber–radio–fiber system in beyond 90 GHz using low loss optical modulator and direct photonic down-conversion. We successfully transmitted 32-/64-QAM OFDM and single-carrier signal with a record line rate of 71.4 Gb/s and net data rate of 53.7 Gb/s.
