Cleaning Regimen C – After both Regimen A and B are deemed insufficient
12.
At this point, if material of any type remains on either end face, proceed to the use of
a wet cleaning fluid such as Chemtronics Electro-Wash PX or equivalent.
a. Apply Electro-Wash PX cleaner – (F.I.S. part #F1ES810) - to a cleaning swab, as in step #9.
b.
Rub swab over the entire end face of the dirty connector with moderate pressure to
remove any remaining contaminants.
c. Immediately dry the end face with the dry cleaner, as in step #5.
13. Repeat steps 12a, 12b and 12c until all visual contaminants are removed.
14.
If upon inspection, the end faces prove to be free and clear of any contaminants, proceed to mate
the connectors.
15.
If after several attempts with cleaning regimen “C”, any end faces remain insufficiently free of
contaminants, (Per IEC 61300-3-35 document) consider replacing the offending connector(s).
NOTES:
•
For definition of acceptability based upon artifacts left on fiber end face, refer to section 6 of the IEC
61300-3-35 document (FO Interconnecting Devices – Basic Test and Measurement Procedures).
•
When incorporating the use of 99% IPA, keep bottle closed at all times when not in use. 99% IPA is
extremely volatile and prone to contamination from moisture in the air.
•
At operator’s discretion, regimen “B” can be skipped and regimen “C” can be implemented
immediately, once cleaning regimen “A” has proven to be insufficient.
9.0 Troubleshooting Unacceptable Interconnect Performance
Unacceptable interconnect performance due to cleanliness issues of the optical interfaces can be
localized to certain areas of the network and can be grouped into assignable causes/locations for the
degraded performance:
A. Permanent Link Related
These failures occur primarily in the patch field (permanent connector, patch cord or adapter). This
could be caused by improper dressing of the jumpers and cables, improper keying/seating of
connectors, contamination of the connection, or improper cable routing and localized damage (in
the enclosure).
B. Equipment Related
Over/under driving the optical transmission will cause either total or intermittent failure. This can
be caused by improper keying or seating of connectors into the transceivers, contamination of the
patch cord connector, or contamination of the OSA (Optical Sub-Assembly) of the transceiver. Do
not attempt to clean any equipment parts without consulting manufacturer’s specifications.
C. Installation Related
Installations occurring around previously installed fiber networks can also create failures due to
lack of attention in dressing, termination issues and cable routing. These can be assigned to
either the permanent link or the optics receptacles in the active equipment.
D. Construction/Maintenance Related
In local area networks; cuts through walls and ceilings, extensive pulling (resulting in tensile
faults), mistakenly cutting cables, improper clamping, and breaking fibers at the connectors are
examples of localized failures due to poor cable identification or lack of care by workers.
Inspection of connectivity for cleanliness and defects is the recommended place to start
troubleshooting the physical network. Guidelines for recommended actions based on
certain conditions are presented in Table 2 below.
