Analysis of high speed transmission with cascaded discrete lump elements

The motif of this paper to research analysis of cascading test fixture (Module Compliance Board Host Compliance Board and SFP+ connector) for SFP+ cable. Analysis of cascading test fixture (Module Compliance Board? Host Compliance Board and SFP+ connector) for SFP+ cable simulated by EM simulator and using vector network analyzer to validate frequency domain and time domain results. From the simulation and measurement data, the effect of surface roughness for insertion loss is serious and although the connector at a discontinuous transition can achieve impedance matching, the equivalent of LC tank due to matching structure will contribute to transmission zero in frequency response, deep in Sdd21.Furthermore, the near-end crosstalk, NEXT, is also increased at those frequencies.
