Abstract :
The performance of Multiband-Orthogonal Frequency Division Multiplexing (MB-OFDM) Ultra-WideBand (UWB) signal over single mode fiber system using a low cost Electro-Absorption Modulator (EAM) integrated laser (EML) is studied experimentally. Error Vector Magnitude (EVM) measurement is carried out to evaluate the system performance considering the effect of bias voltage, bias current temperature and optical modulation index of the EML, and fiber length. The experiment results showed that by using an EML, the UWB signal transmission over fiber can be cost effectively implemented.
