Abstract. 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 com-mercially 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.
