Abstract
We studied the coherent crosstalk properties of a novel time-slot tuner and its implications on the scalability of large-scale OTDM interconnects. A statistical model for the coherent crosstalk was used to evaluate the performance degradation which arises from the coherent interference between signal and crosstalk fields. Based upon this highly scalable, rapidly tunable channel selector, large all-optical TDM switching interconnects up to 100 nodes with an aggregate bandwidth of hundreds of Gb/s can be feasible, using off-the shelf electro optical (E/O) modulators with on/off extinction ratios of 30 dB. The results show the potential to further scale the size of the system up to hundreds of nodes, given on/off extinction ratios of 35-40 dB for the modulators.Keywords
