An impairment-aware resource allocation algorithm for flexi-grid networks with all-optical add/drop capability is proposed. The performance of such a network is compared with legacy solutions.(More)
The idea behind flexible optical transmission is to optimize the use of fiber capacity by flexibly assigning spectrum and data rate adapted to the needs of end-to-end connection requests. Several(More)
The optimum spectrum granularity for sub-channel allocation within super-channels is evaluated according to the Nyquist-shaping characteristics of ultra-fine resolution filters. Optimized blocking(More)
A cascade of two-stage coarse and fine WSS is studied for Nyquist- and quasi-Nyquist WDM systems. Results show that edge tributaries experience excess performance degradation, resulting in a(More)
