OPERATING POINTERS & TROUBLESHOOTING
Optical Cable:
The AC1037A operates with most single mode (SM) optical fibers. However, be aware
that the type of fiber you use will affect the system's loss budget and the maximum
transmission distance that it can support.

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
whenever 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 VIDEO and AUDIO indicator LEDs should provide the first clue as to the
origin of an operational failure. If these are off, it usually means that the fiber is broken or
has too much attenuation. Next, be certain that the input and output signal connections are
correct.
If, after reviewing the above possibilities, the system is still not operating, please contact
the Customer Service Department for further assistance.
Maintenance:
The only maintenance of the AC1037A system that can be provided by the user is to
ascertain that the optical connectors are free of dust or dirt that could interfere with light
transmission and that electrical connections are secure and accurate. DANGER! Always
disconnect the transmitter power before removing the optical fiber from the unit! For as-
sistance with all other repairs, please contact Black Box technical support.
