Optical Orthogonal Frequency Division Multiplexing (OOFDM) is a novel optical signal transmission technology, which
can access to high performance in existing fiber channel especially the Multi-Mode Fiber channel. This paper shows a
numerical simulation of the transmission performance of Adaptively Modulated Optical Orthogonal Frequency Division
Multiplexing (AMOOFDM) system in MMF and SMF channel with Adaptive Cyclic Prefix (ACP), using directly
modulated DFB lasers and Intensity-Modulation and Direct-Detection (IMDD). According to the modulation format
based on channel estimation and Adaptive Cyclic Prefix, it is shown that 12.5Gbps over 1km in typical MMF channel
and 12.5Gbps over 500km in SMF channel are feasible.
Within the realm of OFDM research, (peak-to-average power ratio)PAPR is an important object to be considered.
Overlarge PAPR can deteriorate the linearity of the wireless systems. In this paper, we interpret the concept of PAPR in
optical OFDM system and testify that the modulation method in sub-carriers and nonlinear effects can affect PAPR in
the optical OFDM system. Through simulation, PAPR problem stand out while considering OFDM in optical
transmission technology, so reducing it has become an important subject in optical OFDM system.
