Chapter 2 Cleaning the Optical Array Cable Connectors

How to Clean the Optical Array Cable Connectors

Each optical array cable connector contains six optical ferrules. To access all ferrules, you must clean

three ferrules and then rotate the adapter 180 degrees to clean the remaining three ferrules. This section

describes the process to clean all ferrules in an optical array cable.

Warning

Because invisible radiation may be emitted from the aperture of the port when no fiber cable is

connected, avoid exposure to radiation and do not stare into open apertures.

Statement 125

Warning

Class 1M laser radiation when open. Do not view directly with optical instruments.

Statement 281

Caution Before you begin, review the “General Reminders and Warnings” section on page 1-2.

To clean the optical array cable connectors, follow these steps:

Step 1 Attach an ESD-preventive wrist strap to your wrist and connect its leash to an ESD connection socket or

a bare metal surface on the chassis.

Step 2 Attach the adapter, as shown in Figure 2-2. Be sure to align the pins on the cable with the pin holes on

the adapter.
