Fiber Optic Cleaning Guidelines
Fiber Optic transmitters and receivers are extremely susceptible to contamination by particles
of dirt or dust, which can obstruct the optic path and cause performance degradation. Good
system performance requires clean optics and connector ferrules.
1.
Use fiber patch cords (or connectors, if you terminate your own fiber) only from a
reputable supplier; low-quality components can cause many hard-to-diagnose problems
in an installation.
2.
Dust caps are installed at Black Box to ensure factory-clean optical devices. These
protective caps should not be removed until the moment of connecting the fiber cable to
the device. Should it be necessary to disconnect the fiber device, reinstall the protective
dust caps.
3.
Store spare caps in a dust-free environment such as a sealed plastic bag or box so that
when reinstalled they do not introduce any contamination to the optics.
4.
If it is suspected that the optics have been contaminated, alternate between blasting with
clean, dry, compressed air and flushing with methanol to remove particles of dirt.
Electrostatic Discharge Precautions
Electrostatic discharge (ESD) can cause damage to any product, add-in modules or stand
alone units, containing electronic components. Always observe the following precautions
when installing or handling these kinds of products
1.
Do not remove unit from its protective packaging until ready to install.
2.
Wear an ESD wrist grounding strap before handling any module or component. If the
wrist strap is not available, maintain grounded contact with the system unit throughout
any procedure requiring ESD protection.
3.
Hold the units by the edges; do not touch the electronic components or gold connectors.
4.
After removal, always place the boards on a grounded, static-free surface, ESD pad or in
a proper ESD bag. Do not slide the modules or stand alone units over any surface.
WARNING!
Integrated circuits and fiber optic components are
extremely susceptible to electrostatic discharge damage. Do not
handle these components directly unless you are a qualified service
technician and use tools and techniques that conform to accepted
industry practices.
