Abstract
Tolerance to cascaded WSS filtering is studied for QPSK, 8QAM, and 16QAM formats operating at 32 GBaud. Channel spacing, WSS filter shape, and DSP parameters are considered, and recommendations are made for performance optimization using methods which are practically implementable in modern hardware.
