Abstract
We show how dynamically adjustable modulation formats can be used to reduce optical path operating margins in Flexgrid networks, reverting to lower order reduced OSNR QAM if ageing occurs. Spectral savings amount to as much as 63% across a network but due to use of 64QAM, a fine frequency granularity of 6.25GHz is required.
