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. Do not set connectors contact end down. Install the high-speed connector protective
end caps when the QSFP-DD TPA is not in use.
Visual Inspection
Be sure to inspect all cables carefully before making a connection. Inspect all cables for
metal particles, scratches, deformed threads, dents, or bent, broken, or misaligned center
conductors. Do not use damaged cables.
Cleaning
If necessary, clean the connectors using low-pressure (less than 60 PSI) compressed air or
nitrogen with an effective oil-vapor filter and condensation trap. Clean the cable threads, if
necessary, using a lint-free swab or cleaning cloth moistened with isopropyl alcohol. Always
completely dry a connector before use. Do not use abrasives to clean the connectors. Re-
inspect connectors, making sure no particles or residue remains.
Making Connections
Before making any connections, review the “Care and Handling Precautions” section. Follow
these guidelines when making connections:
• Align cables carefully
• Make preliminary connection lightly
• To tighten, turn connector nut only
• Do not apply bending force to cable
• Do not over-tighten preliminary connections
• Do not twist or screw-in cables
• Use an appropriately sized torque wrench, and do not tighten past the “break” point of the
torque wrench (normally 5 inch pounds)
