Fiber Weave Effect - a performance-limiting factor

Fiberglass weave patterns in a dielectric material influence the voltage and timing margins by adding skew in a differential pair traces due to unequal velocities of the transmitted signals, converging to a less differential signal at the receiver that contributes to intersymbol interference, closer eye, reduced bit-error-rate (BER) and increased electromagnetic interference (EMI). The Fiber Weave Effect (FWE) is simulated in the present paper through the MWO environment presenting an overview of this performance-limiting factor for differential signaling.
