Soliton ultrafast all-optical mesh networks

Channel transmission error arguments show how the size of an all-optical multihop network employing deflection routing is limited for a given optical bit rate. ...
It is found that the node-to-node fibre span cannot exceed a few kilometres for network sizes up to 400 nodes when the optical bit rate is as high as 100 Gbit/s if the packet error rate is to be bounded ...
This increases nonlinear distortion in the fibre, which, together with chromatic dispersion and the optical noise introduced by the optical amplifiers, contribute to increase the probability of error in ...
