4.3.2 Cleaning Optical Ports
These instructions are recommended only when there is evidence of contamination or when reduced
performance has been detected. Clean the optical ports as follows:
1. If required, remove the fiber optic connector from the optical port and clean the connector as
described in “Cleaning Connectors” on page 4-3.
2. Insert the extension tube, supplied with the canned air, into the canned air nozzle and blow out the
optical port. Use care not to touch the bottom of the optical port.
3. Reconnect the fiber optic connector removed in step 1.
If degraded performance persists, perform the following additional steps:
4. Remove the fiber optic connector and place a dust cap on the end.
5. Using a small head swab gently wipe out the optical port. Repeat steps 2 and 3.
LASER WARNING: Laser output can cause serious damage to the eye. The lasers used in
the
DS2000-IFR produce light that is invisible to the naked eye. It must be assumed at all
times that the fiber optic cables and optical ports are radiating light energy. When
connecting or handling the fiber cables or connectors, it is imperative that the technician
avoid looking into the tip of the fiber or the optical port.
