Cleaning Fiber-Optic Ports

For proper performance of PICs that use fiber-optic cable, you must clean the fiber-optic transceivers before inserting cable.

Because of the high sensitivity of fiber-optic PIC receivers, you must keep the PIC ports clean and free of dust. Small microdeposits of oil and dust in the canal of the port could cause loss of light, reducing signal power and possibly causing intermittent problems with the optical connection.

Keep the ports clean by using an appropriate fiber-cleaning device. Follow the directions for the cleaning kit you use. Some PICs may include fiber-cleaning swabs. See Figure 20 for the proper cleaning procedure.

After you have cleaned the optical transceiver area of the fiber-optic PIC, make sure that the connector tip of the fiber-optic cable is clean.

To clean the fiber-optic cable connectors, use only an approved alcohol-free fiber-optic cable cleaning kit. Follow the directions for the cleaning kit you use.
