This paper deconstructs the conventional approach to optical power budgeting and introduces the Signal-to-Noise Ratio (SNR) as a fundamental metric for budgeting with next-generation modems. It shows how SNR-based budgeting simplifies noise segregation, improves performance margin estimation, and demonstrates a vendor-agnostic approach to measurable performance indicators of a cable.
