2. Introduction

2.1 General

The FiberPath is a high-quality, cost-effective fiberoptic
video transmission system designed to transmit color
and black-and-white signals over distances of more than
a mile. The system is easy to install and is designed for
long, trouble-free operation in most indoor or outdoor
protected environments. The FiberPath is compatible
with all standard analog video formats, including NTSC,
PAL, and SECAM, and will operate with all standard

62.5 micron fiberoptic cables and industry-standard ST
type connectors.

3. Installation

Figure 3-1 on page 12 may provide assistance during
installation. Follow these steps:

1. Mount the FiberPath Transmitter at the camera
or source of video to be transmitted. Use the
mounting tabs on the housing or the enclosed
self-adhesive mounting pad.

2. Connect one of the plug-in power supplies to the
input connector on the FiberPath Transmitter. If
you plan to use an external power source, make
sure that it provides regulated 12-VDC ±10%.
Current from this source will not exceed 250 ma.
When power is applied, the red PWR LED
indicator will glow.

NOTE

The negative (-) side of the power input is connected to the
enclosure.

3. Connect the video signal to be transmitted to the
BNC connector on the FiberPath Transmitter, and
the ST fiberoptic cable plug to the transmitter’s
optical connector.

4. Mount the FiberPath Receiver at the monitor or
device where the video will be received. Use the
mounting tabs on the housing or the enclosed
self-adhesive mounting pad.

5. Connect the remaining plug-in power supply to
the FiberPath Receiver’s input connector. If you
plan to use an external power source, make sure
it provides regulated 12-VDC ±10%. Current from
this source will not exceed 250 ma. When power
is applied, the red PWR LED indicator will glow.

NOTE

The negative (-) side of the power input is connected to the
enclosure.

6. Connect the video monitor or other video
receiving device to the BNC connector on the
FiberPath Receiver and the fiberoptic cable plug
to the optical connector on the Receiver.

7. For a pleasing picture, slowly adjust the LEVEL
control on the FiberPath Receiver. If you require
high accuracy, set this level to 1 volt pp with a
75-ohm load.

8. Your FiberPath video transmission system is now
installed.

4. Troubleshooting

If your FiberPath transmission system does not
immediately operate, follow this checklist:

1. Is the correct operating power present and
connected to the proper pins on the power
connector? If so, the red PWR LED should glow.

2. If you’re using an external power source, does
it matter that the signal and power ground are
connected to the enclosure?

3. Is a video signal present at the FiberPath
Transmitter input?

4. Are you using the proper 62.5 micron fiberoptic
cable?

5. Is the fiberoptic cable more than 1.5 miles
(2.4 km) long? If so, a weak, snowy picture
may result.

6. Are the fiberoptic connector ends free of any
minute dust or dirt particles? If not, use a lint-free
cloth moistened with a drop of alcohol to gently
clean the optical surface.

If all of the troubleshooting items on the checklist are
correct and the system still will not operate correctly, call
