FiberLink 7250 Series
Welcome
The FiberLink 7250 Series is a transmitter/receiver pair that transmits a single channel of
RGBHV video (up to WUXGA) and two audio channels over two single mode or multimode
bers. It is available as a free-standing box unit or as a card version for use in the rackmount-
able 6000A card cage.
The system’s all digital encoding delivers noise-free transmissions that retain all of their ini-
tial parameters, regardless of ber optic cable attenuation. System operation may be easily
monitored using integral indicator LEDs on each unit that continuously signify the presence
of baseband video and audio signals.
Features
• Supports VGA, SVGA, XGA, WXGA, SXGA, SXGA+, UXGA and WUXGA (640 x 480 up to
1920 x 1200)
• Supports HDTV resolutions of 480p, 720p, 1080i and 1080p (RGBHV format only)

Installation Instructions
The FiberLink 7250 Series transmission system is ready for immediate use. There are indica-
tor LEDs on the units for monitoring purposes. The following instructions describe the
typical installation procedure and the function of the LED indicators.
1. Connect the video source to the video input HD-15F connector on the transmitter unit.
2. Connect the video output on the receiver unit to the HD-15F connector.
3. Connect the ber optic cables between the two FiberLink units. Each ber may be con-
nected to either Optical 1 or Optical 2 on the receiver, regardless of which output (1or
2) each one is connected to on the transmitter. The system will still operate properly
if the bers are cross-connected. However, please note that any dierence in length
between the two bers must not exceed 20 meters.
4. Connect the audio input signals to the transmitter stereo jack and the audio output to
the receiver stereo jack.
5. Apply power to both FiberLink units. For box versions using DC power connections,
refer to Figure 1.
6. When power is applied, the green POWER LED will
light, indicating the presence of operating power.
The VIDEO LED will give an indication as described
on page 7.
7. The green AUDIO LED will give an indication as
stated on page 7.
8. The system should now be operational.
Note that the rack card version has an additional red LED for indicating the presence of an
alarm condition (loss of signal). Refer to the table on the following page for alarm enables.
Installation Instructions
The transmitting element in the FiberLink 7240 and 7241
transmitter unit contains a solid state Laser Diode located
in the optical connector. 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 sucient intensity to cause
instantaneous damage to the retina of the eye. Direct
viewing of this radiation should be avoided at all times!

Indicator LEDs
The stand-alone box versions of the FiberLink 7250 and 7251 units have three integral
indicator LEDs that are used to monitor the state of the units.
The rack card versions of these products have an additional red indicator LED that lights
when an alarm condition exists. The rack card unit also provides an output to drive a model
6020A Alarm Sensing Module which provides an audible tone and activates a set of contacts
for external signaling purposes.
The status of the LEDs are as follows:

Optical Fiber
The 7250 Series operates with most multimode (MM) and single mode (SM) optical fibers.
However, be aware that the type of fiber you use will aect 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 o, 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.
