Installation Instructions

Cleaning duplex connectors
Clean connectors so that the optical signal is minimally attenuated by the connector.
This procedure is appropriate when you suspect more than dust contamination.
Prerequisites
• a lens-grade, lint-free tissue,for example, Kimwipes.
• an optical-grade isopropyl alcohol (IPA) (98% or more pure).
• a high-quality canned compressed air with extension tube.
Compressed air must be free of dust, water, and oil, or filmy deposits or scratches on the
surface of the connector can result.
• a fiber optic microscope to inspect connectors.
Danger:
Risk of eye injury
When you inspect a connector, ensure that light sources are off. The light source in fiber
optic cables can damage your eyes.
To avoid getting debris in your eyes, wear safety glasses when you work with the canned
air duster.
To avoid eye irritation on contact, wear safety glasses when you work with isopropyl
alcohol.
Procedure steps
1. To remove or retract the shroud, do one of the following.
• On removable shroud connectors, hold the shroud on the top and bottom at
the letter designation, apply medium pressure, and then pull it free from the
connector body. Do not discard the shroud.
• On retractable shroud connectors, hold the shroud in its retracted position.
2. Remove dust or debris by applying canned air to the cylindrical and end-face
surfaces of the connector.
3. Gently wipe the cylindrical and end-face surfaces of both ferrules using a tissue
saturated with optical-grade isopropyl alcohol.
4. Gently wipe the cylindrical and end-face surfaces with a dry tissue.
