Technical Specications
This device emits invisible infrared electromagnetic
radiation which can be harmful to human eyes. The
radiation from this optical connector, if viewed at close
range with no ber optic cable connected to the optical
connector, may be sucient intensity to cause
instantaneous damage to the retina of the eye. Direct
viewing of this radiation should be avoided at all times!

Operating Pointers
Remember to check attenuation of the ber optic cable. The system will only operate
properly if these specications fall within the range of the system’s loss budget.
Troubleshooting
Multimode ber optic cable contains an optical ber with a light carrying “core” that is
only .0025 inches (62.5 microns) in diameter. Single mode ber 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 ber 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 rst clue as to the origin of any operational
failure. If these are o, 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 ber optic cable, and you have an optical power meter, please
take the appropriate measurements prior to contacting support.
Maintenance and Repairs
The Fiberlink® 6654 Series has been manufactured using the latest semiconductor devices
and techniques that electronic technology has to oer. They have been designed for long,
reliable and trouble-free service and are not normally eld repairable.
Should diculty be encountered, Communications Specialties maintains a complete
service facility to render accurate, timely and reliable service of all products.
The only maintenance that can be provided by the user is to ascertain that optical
connectors are free of dust or dirt that could interfere with light transmission and that
connections are secure and accurate.
All other questions or comments should be directed to our Customer Service Department.
It should be noted that many “problems” can easily be solved by a simple telephone call.
