Fiberlink® 6654 Series
Operating Pointers
Remember to check attenuation of the fiber optic cable. The system will only operate
properly if these specifications fall within the range of the system’s loss budget.
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!
Therefore, any minute particles of dirt or dust can easily block the fiber from accepting or
radiating light. To prevent this from happening, always use the provided dust caps when
ever optical connectors are exposed to air. It is also 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 the LED’s should provide the first clue as to the origin of any operational
failure. If these are off, it usually means that the battery has failed in the unit.
If, after reviewing the above possibilities, the system is still not operating, please contact
the Customer Service Department for further assistance. If you suspect your problem is
caused by the optics or the fiber optic cable, and you have an optical power meter, please
take the appropriate measurements prior to contacting support.
