6. Maintenance and Troubleshooting

6.1 Cleaning Fiber Optic Connectors

DANGER: The fiber optic connector carries invisible laser radiation
while working, so should avoid charged operation.
Dirty optical connectors are the leading source of poor performance in a broadband
optical fiber network. Dirty optical connectors lead to optical signal loss and
reflections, which in turn can seriously degrade signal-to-noise (SNR) performance
and, in some cases, distortion performance. We recommend that you clean all mating
fiber connectors before connecting them to an optical transmitter.
In addition, if you suspect that the optical connector of WT-1550-EM10 may have
been exposed to contamination (by a dirty fiber cable connector, for example), you
should properly clean the WT-1550-EM10 optical connector before connecting the
optical fiber.
CAUTION: Improper cleaning of an optical connector can do more harm than
good. Never spray a clean-air product onto the surface of an
optical connector. Spraying air onto an optical connector can
cause condensation on the connector surface, leaving water spots
and trapping dust. Failing to wipe a connector on dry lens paper
immediately after wiping on paper wet with isopropyl alcohol
can also lead to condensation on the connector. Using low-grade
cleaning paper or other cloth to wipe an optical connector can
leave microscopic fibers on the optical connector Surface.

6.1.1 Cleaning Patch Cord or Pigtail Fiber Optical Connectors

To clean optical connectors, we recommend using a fiber optic connector cleaning
cartridge (such as NTT Cletop). If a cleaning cartridge is not available, follow these
steps.
To clean the optical connector of a patch cord or pigtail:
1. Fold a piece of unused dry lens cleaning paper twice, for a four-ply thickness.
2. Use a drop of high-grade isopropyl alcohol to wet part of the paper.
3. Lay the connector on the lens cleaning paper with the tip touching the paper.
4. In one continuous motion, pull the connector from the wet part of the paper to the
dry part.
