Title:
混合ボーレートサブキャリアを有するスーパーチャネル
Document Type and Number:
Japanese Patent JP6930118
Kind Code:
B2
Abstract:
Methods and systems for transmitting superchannels with mixed baud rate subcarriers include modifying baud rates for certain subcarriers in order to improve or equalize optical signal-to-noise ratio penalties incurred during transmission. Additionally frequency shifts may be applied to individual subcarriers. The baud rate modification and frequency shifts may be symmetrical for spectral positions of subcarriers within the superchannel.
