Fibre networks are rather common today almost in many parts of the world and it looks that fibre as the transmission medium is here to stay for some time. Data transmissions in the backbone fibre networks are based on coherent detection principles and use multilevel phase modulations like quadrature phase shift keying used for 100 Gb/s transmission speeds. But there are also new photonic applications with different requirements then raw speeds only. In order to guarantee seamless coexistence of standard and new photonic applications, we evaluate numerical simulations by using commercially available simulation tools. The simulations results show that such coexistence is possible when certain rules are followed. Simulation results are verified on real fibres to ensure reliable operation.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
