Abstract
A bidirectional ROF configuration has been proposed and developed to transmit 80 channels HDTV signal over 80 km SMF integrating mutually injection locking, optical carrier suppression (OCS) and remodulation techniques. LiNbO3 Mach-Zehnder modulator is used at transmitter end to realize the OCS scheme by mixing two complementary signals of 30GHz. RSOA is deployed at the user end to reuse and remodulate the downstream HDTV signal to upstream transportation over same 80km fiber link. The uplink and downlink transmission performances are observed and analyzed by excellent eye-diagram and low bit error rate values.
