Fiber-Optic Connectors
Visual inspection of fiber ends
Visual inspection of fiber ends can be helpful. Con ta min atio n or i mpe rf ect ion s
on the cable end face can be detected as well as cracks or chips in th e fi b er
itself. Use a microscope (100X to 200X magnification) to inspect the entire
end face for contamination, raised metal, or dents in the metal as we ll a s a ny
other imperfections. Inspect the fiber for cracks and chips. Visible imperfec-
tions not touching the fiber core may not affect performance (unless the
imperfections keep the fibers from contacting ).
WARNING Always remove both ends of fiber-optic cables from any instrument,
system, or device before visually inspecting the fiber ends. Disable all
optical sources before disconnecting fiber-optic cables. Failure to do
so may result in permanent injury to your eyes.
Cleaning Connectors
The procedures in this section provide the proper steps for cleaning fiber-
optic cables and Agilent Technologies universal adapters. The initial cleaning,
using the alcohol as a solvent, gently remo ves any grit and oil. If a caked-on
layer of material is still present, (this can happen if the beryllium-copper sides
of the ferrule retainer get scraped and deposited on the end of the fiber during
insertion of the cable), a second cleaning sho uld be performed. It is not
uncommon for a cable or connector to require more than one cleaning.
CAUTION Agilent Technologies strongly recommends that index matching compounds
not be applied to their instruments and accessories. Some compounds, such as
gels, may be difficult to remove and can con tain damaging particulates. If you
think the use of such compounds is necessary, refer to the compound
manufacturer for information on application and cleaning procedures.
