“…[8][9][10] This later can only be done with a reasonable cost when a universal optical transmitter, which is capable of generation both UWB and WDM PON signals, is available. Direct modulation of semiconductor laser was demonstrated to be suitable for high bit-rate PON systems, however the generation of UWB signals by this technique is still challenging.…”

The integration of ultra-wideband (UWB)-over-fiber into passive optical network (PON) is of great interest as it benefits the high bandwidth capability from optical network technologies and the high flexibility from wireless network technologies. The later can only be done with a reasonable cost when a universal optical transmitter, which is capable of generation both UWB and PON signals, is available. Direct modulation of semiconductor laser was demonstrated to be suitable for high bit-rate PON systems, however the generation of UWB signals by this technique is still challenging. Using the chirp properties of directly modulated semiconductor lasers, UWB signals are generated. Different UWB signal waveforms and polarities are obtained. The received electrical spectra conform to the requirements of indoor UWB systems.

“…RF signal/power is carried by a strong optical carrier from central station using optical fiber cables in RoF systems. RF signal is radiated by using very high gain antenna unit to remote sites [3]. It is used to transmit an analog intensity modulation (IM) of laser diode and to receive direct detection (DD) performed by a photodiode.…”

-In this paper, Coded Orthogonal Frequency Division Multiplexing (COFDM) based Radio over Fiber (RoF) system is simulated (for different bit rates) for different modulation techniques to observe impact on system parameter [quality factor (Q)]. Influence of increasing bit rates has been observed for 2 km long linear multimode fiber. To reduce dispersion due to multimode fiber, convolutional encoder (code rate ½, generator polynomial 133 8 , 171 8 ) and viterbi hard decision decoding algorithm are chosen for simulative model of COFDM based RoF system. Transmission of 32 sub-carriers with externally modulated continuous wave laser source gave satisfied results for Q values.
