Cleaning and Inspecting Fibers and Ports
Step 4 If the adapter is dirty, select the appropriate lint-free swab according to the
connector ferrule size.
Step 5 Inspect the connector in the adapter again by using a fiber scope probe.
Step 6 Insert the clean lint-free swab into the adapter.
Step 7 Turn the swab several complete revolutions in the same direction.
Step 8 Properly dispose of the swab.
Never
reuse a swab.
Step 9 Repeat the cleaning process as necessary.
Vendor-Specific Cleaning Techniques
Due to the proprietary nature of many cleaning techniques the supplier should be
contacted for detailed information.
Cleaning MTP Fiber Cable Ends
One of the most important aspects of fiber cabling is ensuring the cleanliness of the cable
ends. One speck of dust or a fingerprint can severely compromise cable transmission
capability. With MTP cables, this possible hazard is compounded because of multiple
fibers and channels per cable.
Note
• Possible loss of service
• Before inserting MTP connectors into OADM or breakout panel
ports, you must clean them with the procedure below. Failure to
follow this procedure may result in loss of service.
This procedure outlines proper MTP cable cleaning procedures.
Step 1 Using a 2.5 mm clean-room swab (See Figure 6), clean dust and debris from
the fiber termination area (See Figure 7 on p.45) between the MTP alignment
pins.
Note
Swabs as shown can be purchased from clean-room and optical
communications equipment suppliers.
