Introduction
This user’s guide documents the QSFP-DD Legacy Plug, QSFP-DD Plug, QSFP-DD RX Plug,
QSFP-DD TX Plug and QSFP-DD Receptacle Test Adapters.
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.
NOTE: To avoid damaging the cables, use the handling techniques
described in the Care and Handling section before making any
connections or configuring a test setup.
Always use a static-safe workstation when performing tests, as
explained in the “Electrostatic Discharge Information” section.

and may be terminated with different connectors and have different color-coding than what is shown.)
