Abstract

The authors investigate the laser diode (LD) over-modulation which causes composite second-order (CSO) distortion and limits the maximum number of loading channels, even if a perfectly linear LD is used. Measured results of CSO are presented as a function of modulation depth for various numbers of channels. The maximum number of channels is found for an ideal LD which has no distortion except the over-modulation area. Using newly developed distributed-feedback (DFB)-LDs for analog transmission, the authors have achieved 64-channel AM-FDM signal transmission of over 8-dB loss, with a fiber launching power of 3 mW, CNR of 51 dB, CSO of less than -60 dBc, and a CTB of less than -65 dBc.<>

80ch AM-FDM信号光传输

作者研究了激光二极管(LD)的过调制问题，该问题会导致复合二阶(CSO)失真并限制最大加载通道数，即使使用完全线性的LD。CSO的测量结果是不同信道数下调制深度的函数。找到了除过调制区域外无失真的理想LD的最大通道数。利用新开发的分布式反馈(DFB) ld进行模拟传输，实现了损耗超过8db的64通道AM-FDM信号传输，光纤发射功率为3mw, CNR为51 dB, CSO小于-60 dBc, CTB小于-65 dBc。
