Caution
Bending an optical fiber to a radius of less than 30mm, can cause the fiber
to break or produce micro defects in the fiber. Micro defects can affect product safety,
increase fiber attenuation, and reduce long term stability. Ensure that the bending
radius of the fiber is not less than 30mm.
Splicing
Only trained personnel are allowed to cut and splice optical fibers. Always read and
be sure that you understand all the instructions in the documentation related to
splicing and cutting equipment. Before splicing, verify the fiber is disconnected from
the optical component.
After completion, check every splice according to the instructions in the
documentation related to splicing and cutting equipment.
Cleaning optical connectors and couplings
Before cleaning optical connectors, verify that the optical source is switched off.
Never look into the end of an exposed fiber or optical connector when the optical
source is switched on. Always observe the laser warning instructions.
Optical connectors should be cleaned if problems are encountered that indicate the
connectors have an impurity. (For example, attenuation is beyond the maximum
value permitted.)
To check for impurities (dust particles or other contamination), examine the
connector face with a microscope that has an enlargement factor of 200.The physical
geometry of the coupling does not allow it to be checked under a microscope.
Visually check a coupling for residual impurities by holding it to light.
Prior to connection, verify that the optical connectors and couplings are free of
impurities. You can clean the coupling with a pipe cleaner and isopropanol. Let the
isopropanol on the connector coupling face evaporate completely by air-drying, or
with the use of purified compressed air.
