40 Gb/s backplane Ethernet channel characterization

The design of 40 Gb/s (Gb/s = Gigabit per second) backplanes requires the selection of suitable connectors and PCB base materials. To ensure the performance of the backplane, it is crucial to define design rules based on channel simulations. At the same time, it is important to find the balance between costs and performance. Measurements validate whether the backplane is within the interconnect characteristics limits.
