Cleaning and Maintaining Fiber-Optic Connectors

Connector cleaning is required to maintain the performance of fiber-optic circuits. It is important that both the LC/UPC connector at the end of the fiber-optic cable and the optical mating adapter on the front panel of the device are clean before the connection is made.


Warning

Statement 1051—Laser Radiation

Invisible laser radiation may be emitted from disconnected fibers or connectors. Do not stare into beams or view directly with optical instruments.

The following warning applies to disposal of chemicals and other materials used to clean connectors and adapters:


Warning

Statement 9001—Product Disposal

Ultimate disposal of this product should be handled according to all national laws and regulations.


Note

Before installing the fiber-optic cable, always perform the cleaning procedure for cable connectors described in the following section. Whenever possible, inspect each connector before connecting it to the optical mating adapter on the front panel.


Note

The LC optical mating adapter on the faceplate of the device is less likely to get dirty if it is capped when not in use. On some devices, the optical mating adapter has a shutter. The shutter automatically closes when the LC/UPC connector is disconnected. This prevents entry of dirt.

The procedure for a thorough cleaning of these adapters is complicated. Use a commercially available cleaning kit and closely follow the instructions included with the kit.

Clean Fiber-Optic Cable Connectors

This task describes the steps to clean the fiber-optic cable connectors.

The tools required to clean fiber connectors are:

  • Inspection microscope

  • Type A fiber-optic connector cleaner (CLETOP reel)

  • Optical swab

  • Optical receiver cleaning stick

Procedure

Step 1

Using an inspection microscope, inspect each fiber connector for dirt, cracks, or scratches.

Step 2

Replace any damaged fiber connectors.

Note

 
Replace all dust caps whenever the equipment is unused for 30 minutes or more.

Note

 
Do not reuse optical swabs. Keep unused swabs away from work surfaces.

Step 3

Clean the fiber connectors with CLETOP reel:

  1. Remove the dust cap from the fiber connector.

  2. Press the lever down to open the shutter door. Each time you press the lever, you expose a clean wiping surface.

  3. Insert the connector into the CLETOP cleaning cassette slot, rotate one-quarter turn, and gently swipe downwards.

  4. Use an inspection microscope to inspect each fiber connector for dirt, cracks, or scratches. If the connector is not clean, repeat the above substeps.

  5. Insert the fiber connector into the applicable adapter or attach a dust cap to the fiber connector.

    Note

     
    If you must replace a dust cap on a connector, first verify that the dust cap is clean. To clean the dust cap, wipe the outside of the cap using a dry lint-free wipe and the inside it using a CLETOP stick swab (14100400).

Customer-supplied Cleaning Materials

The Type A fiber optic connector cleaners (for example, CLETOP reel) are recommended to clean the cable connectors, but are not supplied with the device.

If properly maintained (only used with clean, defect-free fiber connectors and capped when not in use), the mating adapter would not require cleaning. However, if you suspect the adapter is dirty, clean it by using the CLETOP stick swab.


Note

For multifiber cable assemblies, use specific cleaning tools or materials designed for the assembly type.

Cleaning the Optical Mating Adapter

This task describes the steps to clean the optical mating adapters.

Procedure

Step 1

Read the cartridge cleaning instructions (provided by the manufacturer) to insert the cartridge cleaning tip into the optical mating adapter.

Step 2

Slide the lever on the cartridge to swipe the mating surface.

Note

 

Always keep unused adapter ports and fiber connectors capped with a clean dust cap. The optical mating adapters that have shutter need not be capped.
