研究了利用啁啾光纤布拉格光栅（CFBG）对外调制子载波复用光载无线传输链路中光纤色散引起的功率衰落的补偿。结果表明，通过合理设计光栅参数和优化选择切趾剖面，可以显著减小光纤色散引起的周期性功率衰落，提高最佳传输距离。研究还表明，采用具有非对称切趾轮廓的CFBG作为色散补偿器，156 Mbps DPSK信号的载噪比和误码率也得到了显著改善。
Compensation of fibre dispersion-induced power fading in an externally modulated sub- carrier multiplexed radio-over-fibre transmission link using the chirped fibre Bragg grating (CFBG) has been investigated. The results show that periodic power fading caused by fibre chromatic dispersion is significantly reduced and the optimum transmission distance can be increased by proper design of grating parameters and optimum selection of apodisation profile. The investigation also reveals that carrier-to-noise ratio and bit-error rate of 156 Mbps DPSK signal are also significantly improved using the CFBG with asymmetric apodisation profile as the dispersion compensator.
