indicated on the approved detail drawings
and in compliance with the IFS installation
manual.
Optical Fibers
1. Caution: NEVER look into the end of an

output. Eye damage can occur. Wear eye
protection when cleaving, terminating, and
splicing fiber.
2. The number and type (multimode or singlemode) of optical fiber shall meet the
requirements of the IFS model number in
article 2.06 used in the installation.
3. All optical fiber cables shall be properly
installed and terminated with the mating
optical connectors as submitted in article
2.08 (A).
4. The optical link shall be tested with either a
power meter, at a minimum, or OTDR to
ensure the link budget (overall path loss)
plus an added 3dB of optical safety margin
does not exceed the optical power budget as
submitted in article 2.06.
5. All optical connectors on cable shall be
cleaned in compliance to optical connector
manufactures specifications and covered
with dust caps until connection to the fiber
optic module.
INSTALLATION
General: Locate fiber optic modules as indicated
on the approved detail drawings and install
module in compliance with the IFS installation
and operations manual.
TESTING
Testing the Fiber Optic Video Link.
1. Verify that the coax and optic fibers are
properly connected.
2. Make sure that power is applied to all fiber
optic modules, camera, and video monitor or
other equipment used in the system.
3. The carrier detect indicator LED should be
lit confirming a presence of a video signal.
4. Successful video link operation should be
visible at this point as witnessed by a good
quality video picture on the monitor.
Testing the Fiber Optic Data Link.
1. Verify that the data leads and optical fibers
are properly connected.
2. Make sure that power is applied to all fiber
optic modules, controllers, and receiver
drivers or other equipment used in the
system.
3. Successful data link operation should be
confirmed at this point by using the
controller to pan, tilt, and zoom the camera
or communicate with other equipment.
CLEANING
Section Title
A. Follow all instructions for proper use of solvents
and adhesives used for termination and splicing.
