- High baud rates can increase throughput, but they also increase the spectral width and require more sophisticated filtering and higher-quality optical components. Higher-order modulation formats (e.g., 16-QAM, 64-QAM) allow engineers to increase the bit rate without expanding the spectral width.

Factors that affect bit rate and baud rate performance in optical networks include transmission distance, optical power, fiber type, modulation technique, and channel bandwidth. How can bit rate and baud rate be measured in optical networks?
Increasing the baud rate for a line card or appliance may increase the capacity per wavelength and eventually reduce the power per bit. But the spectral efficiency, and therefore total fiber capacity, at best stays the same. Nyquist subcarriers are a vital capability to optimize optical performance as baud rates
