The continuous growth of IP traffic in combination with emerging applications with various bandwidth demands is driving the introduction of elastic optical network (EON) with flex grid. EON can increase spectrum utilization by better matching data rate with the allocated bandwidth and improve the spectral efficiency by multi-carrier and high-order modulation solutions. In this article the architecture...
We propose a modulation-format-aware power equalization method for heterogeneous elastic optical networks. We show the benefit by simulation based on an optical OFDM superchannel with mixed modulation formats.
