    Model Numbers (QSFPDD-TPAK-HCB-LGCY-P, QSFPDD-TPAK-HCB-DD-P, QSFPDD-TPAK-HCB-RX-P, QSFPDD-TPAK-HCB-TX-P and QSFPDD-TPAHK-MCB-R). The two test adapter types, shown in Figures 1 and 2, test QSFP-DD interface cables, hosts, and modules to the requirements of the QSFP-DD MSA and IEEE 802.3cd Standards. The QSFP-DD HCB (Plug) and QSFP-DD MCB (Receptacle) test adapter assemblies allow easy access, via 2.92mm (K-Style) connections, to measure or inject data signals.

The QSFP-DD MCB (Receptacle) Test Adapter (Note: The coaxial cables are configuration dependent and may be terminated with different connectors than what is shown.) NOTE: The metal shell of both the plug (QSFP-DD HCB) and receptacle (QSFP-DD MCB) connectors tie high-speed ground to chassis ground.

  • Page 6: The Qsfp-Dd Test Adapter Care And Handling Precautions

    If the QSFP-DD TPA must be turned or twisted to make connection to the DUT, avoid using the QSFP-DD TPA housing alone to make this occur. Try to distribute the torque forces along the length of the test setup and cabling.
  • Page 7 • CAUTION 7: ESD Sensitivity The QSFP-DD test adapters are passive components and are not in themselves sensitive to electrostatic discharge. However, when an active DUT is installed, that device becomes susceptible to ESD. Observe proper ESD precautions, further discussed later in this document.

  • Page 8: General Test Adapter, Cable, And Connector

    Observing simple precautions can ensure accurate and reliable measurements. Handling and Storage Before each use of the QSFP-DD TPA, ensure that all connectors are clean. Handle all cables carefully and store the QSFP-DD TPA in the foam-lined instrument case when not in use, if possible.

  • Page 9: Electrostatic Discharge Information

    Electrostatic Discharge Information Protection against electrostatic discharge (ESD) is essential while connecting, inspecting, or cleaning the QSFP-DD TPA test adapter and connectors attached to a static-sensitive circuit (such as those found in test sets). Electrostatic discharge can damage or destroy electronic components. Be sure to perform all work on electronic assemblies at a static-safe work station, using two types of ESD protection: •...

    QSFP-DD Test Adapter User Manual User Model The QSFP-DD TPAs are capable of performing to the requirements of both IEEE and SFF specifications, limited only by the specifications, environmental, care and handling of this document. In the case where the laboratory source or load is not used in the test, it must be replaced with RF terminations on each unused signal.
