High-speed backplane for optical network product

【TYPE】： High-speed backplane for optical network product
【Difficulty】： More than 320 differential pairs with 3.125G signal. And 640+ differential pairs with 3.125G signal. The PCB size is 653 X 418. The Insertion loss is a big problem with long trace. And return loss is also a problem in case the impedance mismatch. We also considering the crosstalk and EMI.
【Solution】： Extract Via model and trace model in HFSS. Eye diagram Simulation with HSPICE.S parameter analysis for Insertion loss and return loss.
【Result】： Reduce the layer from 32 to 28 with good signal quality. It's better for PCB fabrication.
