Clean and Apply Dielectric Grease to a Fiber Transceiver Edge Connector (XT)

If the dielectric grease on a transceiver edge connector contains debris or is removed to expose the edge connector before installation, you must thoroughly clean and reapply PolySi PST-576 nonsilicone, dielectric grease to the affected connector.
IMPORTANT: Only PolySi PST-576 dielectric grease is approved for use on edge connectors of circuit boards with XT.
The grease applicator kit, catalog number SK-RM-GRAPP1, is available to reapply grease to edge connectors on fiber transceivers. See Dielectric Grease Applicator Kit.
Follow these steps to use the grease applicator kit to apply dielectric grease to a transceiver edge connector on a fiber transceiver.
  1. By using a lint-free alcohol wipe with 90% or higher alcohol content, remove any debris away from the transceiver edge connector.

  2. Before you apply grease, allow the edge connector to dry thoroughly.
  3. Open the grease tube and, if necessary, by using the pin on the side of the large applicator, puncture the seal on the end of the tube.
  4. Install the small grease applicator on the threaded tip of the tube.
  5. Press the tube until the small cavity of the applicator tip is filled completely with grease.
  6. TIP: The tip is full when grease reaches the end of the small cavity on the tip of the applicator. Do not over-fill the small cavity with grease.
  7. To apply dielectric grease, insert the edge-connector end of the transceiver into the applicator tip.

  8. TIP: The transceiver edge connector fits into the small, inner cavity with the grease, and the outer transceiver case fits into the outer cavity of the applicator.
  9. Remove the transceiver from the applicator.
  10. IMPORTANT: Take care not to touch the edge connector before insertion into the fiber-optic port.
  11. After use, remove the small grease applicator from the grease tube.
  12. Replace the cap on the grease tube.
  13. By using a clean cloth, wipe the remaining grease out of the applicator tip.
