Information about these models can be found in Electrical Model Documentation (EE-170382-001_rev3.pdf and EE-170382-0001_revB.pdf) for these modeled data. For the differential requirements the defined SFF-8081 reference board losses, shown below, were added to the modeled connector data. Note, that SFF does not define any common mode insertion losses for the applicable test fixtures. There for no adjustments were made to the connector only common mode data to show conformance. Actual measured values would vary depending on the common mode insertion loss performance of the test fixtures.
