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 B&B Electronics 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 you suspect 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.
