Abstract: All-to-all broadcast is to disseminate a unique message from each node to every other node of the network. This paper investigates the impact of some of the physical layer impairments on the optical all-to-all broadcast in linear array, bidirectional ring and hypercube networks. The physical layer impairments include Amplified Spontaneous Emission (ASE) noise, switch induced crosstalk and demux/mux crosstalk. In all networks, the result shows that for shorter lightpaths, the ASE noise and demux/mux crosstalk are found to be much less as they traverse through few fiber links. Longer lightpaths due to their larger stretch experiences higher accumulated ASE noise and demux/mux crosstalk. In addition, lightpaths of a hypercube network suffer switch induced crosstalk at all the nodes along its path. A few measures to reduce the impact of transmission impairments are suggested since the control signals in a network should be highly reliable.
