Storing optical connectors

All switch cards are shipped with dust caps in place covering all optical connectors. Opti-
cal connectors should remain covered at all times when the card is not in use.

Cleaning optical connectors

Clean any exposed connector using a cleaning kit supplied by the connector manufacturer
or high-grade isopropyl alcohol and a cotton swab. To clean with alcohol and a swab, dab
the tip of a cotton swab in alcohol and then shake off any excess alcohol. The tip should be
moist, not dripping wet. Stroke the swab tip gently across the surface of the connector and
around the connector ferrule. Either allow the connector a minute to dry, or blow-dry the
connector using clean compressed air. Be careful when using compressed air because
improper use may deposit a spray residue.
Do not pull on the bare fiber. Doing so can break the fiber inside the component.
Avoid using soldering irons near optical cable. Accidental damage can easily occur
when a soldering iron is used near an optical cable. In addition, solder splatter can
contaminate and permanently damage optical fiber connectors.
In order to obtain the most stable, repeatable optical performance, immobilize opti-
cal cables using wide pieces of tape or some form of mechanical cushion after the
optical cables have been connected.
