Abstract
A high-speed transmission circuit design reduces or eliminates the presence of unwanted stub-effects and avoids uncontrolled line impedances that in existing circuits cause impedance mismatches that give rise to unwanted reflections and, ultimately, degrade signal integrity, e.g., in belly-to-belly configurations involving Quad Small Form-Factor Pluggable Double Density (QSFP DD) connectors. In various embodiments, by preventing overcrowding of signal lines, the circuit design further reduces crosstalk and increases signal integrity.
