Characterisation of DSB-OCS technique for 40GHz radio over fibre system

The dual sideband optical carrier suppression (DSB-OCS) technique is characterised for its performance in order to be used as a carrier for 1.25Gbps OOK signal in the 40GHz radio over fibre (ROF) system. A dual electrode Mach-Zehnder modulator (DE-MZM) and the minimum transmission bias (MiTB) techni...

Description
Summary:The dual sideband optical carrier suppression (DSB-OCS) technique is characterised for its performance in order to be used as a carrier for 1.25Gbps OOK signal in the 40GHz radio over fibre (ROF) system. A dual electrode Mach-Zehnder modulator (DE-MZM) and the minimum transmission bias (MiTB) technique are employed to build the system. The results show that, a 40GHz carrier is successfully generated with the amplitude up to -29dBm and SNR of 35dB. Finally, an error free 40GHz ROF system is constructed with almost no penalty between the back to back and 20km fibre for a BER of 10 -9 .
