摘　　要：We experimentally demonstrate the multiband orthogonal frequency-division multiplexing ultra-wideband （MB-OFDM UWB） over fiber system with direct detection. Different sub-carrier modulation formats （quadrature phase shift keying （QPSK） and 16 quadrature amplitude modulation （QAM）） are investigated in the MB-OFDM UWB over fiber system. The experimental results show that a 3.84 Gb/s 16 QAM-encoded MB-OFDM UWB signal can be successfully transmitted over 70 km standard single-mode fiber without chromatic dispersion compensation.We experimentally demonstrate the multiband orthogonal frequency-division multiplexing ultra-wideband （MB-OFDM UWB） over fiber system with direct detection.
