Mathematical modelling of all-optical buffering for ultrafast optical time division multiplexed networks.
… This work finds a niche in this domain where the physical effects of the buffer components (e.g. optical switches) have not been previously documented. In order to optimise the bit error rate performance and characterise its dependence on the physical buffer characteristics, the buffer models are …
