Power:
ON: (GREEN) Indicates that correct power has been applied.
Video:
OFF: Indicates no video detected on the input.
BLINKING GREEN: Indicates either H or V sync detected at
the input but not both.
STEADY GREEN: Indicates both H and V sync detected on
the input.
Audio:
OFF: Indicates no audio detected on the transmitter unit.
BLINKING: Indicates audio detected on the transmitter unit.
Indicator LEDs:
The Pure Digital Fiberlink

7222, 7224 and 7226
transmitters each have three integral indicator LEDs that are used to
monitor the state of the unit.
The status of the LEDs are as follows:
OPERATING POINTERS AND TROUBLESHOOTING
Optical Fiber:
The 7222, 7224 and 7226 transmitters operate with most
multimode (MM) and single mode (SM) optical fibers. All models within
the 7220 Series use the same 1310 nm wavelength and optics for trans-
mitting over multimode or single mode fiber, but 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!
