【摘要】 利用自制的窄带光纤Bragg光栅(NFBG)获得了单边带(SSB)调制信号,并在标准单模光纤(G.652)上分别进行双边带(DSB)和SSB调制信号的传输,传输了155km G.652后采用自制的啁啾光纤Bragg光栅(CFBG)进行色散补偿。结果表明,在同样的入纤光功率下获得相同的误码率(BER),SSB信号的功率代价比DSB信号的小,在BER为E-12数量级时,SSB信号的功率代价比DSB信号小0.8dB。更多还原

【Abstract】 Optical singal sideband(SSB) modulation is obtained by the narrow fiber Bragg grating(NFBG) fabricated by ourselves.The double sideband(DSB) and SSB modulation are transmitted over 155 km standard signal mode (G.652) fiber, and compensated by chirp fiber Bragg grating(CFBG).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.更多还原
