Variable Spectral Loading refers to the dynamic adjustment of spectral power or wavelength allocation in optical or wireless communication systems. It optimizes channel utilization and energy efficiency under changing traffic conditions. Adaptive control of spectral resources improves data throughput and signal integrity. Researchers use this technique to design flexible, high-performance transmission networks. It represents an important step toward intelligent spectrum management.
We experimentally investigated variable spectral loading in an OMS, identifying performance under best and worst transmission conditions. Metrics and data visualization allowed correlation between channel configurations and OSNR variations, enabling the derivation of a simple spectrum allocation rule.
