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 com-
pounded because of multiple fibers and channels per cable.
This procedure outlines proper MTP cable cleaning procedures.
Procedure
Step 1
Using a 2.5 mm clean-room swab (See
Figure 94
), clean dust and
debris from the fiber termination area (See
Figure 95
) between the
MTP alignment pins.
