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

Warning

Invisible laser radiation may be emitted from disconnected fibers or connectors. Do not stare into beams or view directly with optical instruments. Statement 1051

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

Warning

Ultimate disposal of this product should be handled according to all national laws and regulations. Statement 1040

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 mating bulkhead adapter on the front panel.

The LC/MPO bulkhead adapters on the optical modules are less likely to get dirty if they are capped when not in use. Because the procedure for a thorough cleaning of these adapters is complicated, we recommend that you use a commercially available cleaning kit and closely follow the instructions included with the kit.

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

When cleaning a paired cable connector (bulkhead mating adapter), always clean the mating adapter first.

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 multi-fiber cable assemblies, use specific cleaning tools or materials designed for the assembly type.
