Fortunately,optical modulation formats have good characteristics on spectrum, dispersion and nonlinearity tolerance. So,using correct modulation format based on the difference condition is a right choice of improving the performance of the systems.
而不同的调制格式在色散容限、非线性的容纳能力、频谱利用率等方面具有各自的特点,根据实际情况,选择合适的调制码型,并将码型调制技术和其他光纤传输技术相结合,是提高通信传输质量的有效途径。
