5. Troubleshooting
Multimode fiber optic cable contains an optical fiber with a light carrying "core"
that is only .0025 inches (62.5 microns) in diameter. Single-mode fiber optic cable
has an even smaller "core," only 00032 to .0004 inches (8-10 microns). This is
smaller than a human hair. As a result, any minute particles of dirt or dust can
easily block the fiber from accepting or radiating light. Therefore, the key word is
cleanliness. Always use the dust caps provided with all optical connectors when-
ever they are exposed to air. Also, it is a good idea to gently clean the tip of an
optical connector with a lint-free cloth moistened with alcohol whenever dust is
suspected.
The status of any of the indicator LEDs should provide the first clue as to the
cause of any operation failure. Be certain that the input and output signal
connections are correct. Because of the number of positions, there may be wrong
connections.
Finally, although multimode and single-mode devices may look the same, they will
not operate properly if used together. Using the wrong device or fiber can easily
add more attenuation than specified, resulting in poor overall performance.
If, after reviewing the above possibilities, the system is still not operating, please
contact Black Box Technical Support at 724-746-5500 or info@blackbox.com for
further assistance.
The only maintenance that can be provided by the user is to make sure that
optical connectors are free of dust or dirt that could interfere with light
transmission and that electrical connections are secure and accurate.
