Optical SSB modulation using fiber Bragg grating and its transmission performance

The single sideband (SSB) modulation format is obtained using the narrowband fiber Bragg grating (NFBG) made by ourselves. Then The SSB modulation format and double sideband (DSB) modulation format transmit over 155 km G.652, respectively. And dispersion is compensated by chirp fiber Bragg grating (CFBG) made by us. The results show that the power penalty of SSB signal is smaller than that of DSB signal when the input power and the bit error rate (BER) are the same; when the BER is E-12, the power penalty of SSB signal is 0.8 dB smaller than that of DSB signal.
