When routing optic fibers, be careful to avoid bending the fibers beyond the
manufacturer recommended bend radius. Exceeding the 1” (2.54 cm) bend radius can
cause excess attenuation and possibly break the fiber. The use of vendor specified
radius clips is highly recommended. Refer to the list of vendors inside the front cover
for information.
y
Verify all optical power levels before connections are made. If excessive loss is noted,
the use of an optical time domain reflectometer (OTDR) may be required. Tests
should be performed using the 1550 nm setting connected to the RF Video Port on
the CWDM.
Installation Considerations
Note: It is assumed that the ONT has been unpacked and checked against the packing list to
ensure all parts are present prior to beginning the installation.
CAUTION! It is critical that you maintain the proper airflow around the ONT
in it's final mounted location. Only surface mount the enclosure. Do not
install siding or other building material around the outside of the enclosure.
Doing so could create excessive heat and product failure.
Various access points are available within the housing which may or may not be used. Prior
to mounting the ONT unit, you need to consider the following variables. Refer to the section
on
ONT Mounting, Access Points, and Clearances (see "ONT Mounting, Access Points and
Clearances" on page 15) covered previously in this guide.
y
Outgoing Services exit the ONT on the bottom of the unit. Do you have sufficient
conduit and/or cable management equipment to properly route the cables?
y
Is there an earth ground connection available near the ONT? If not, you will need to
install the earth ground rod prior to putting the unit into service. Refer to the
Reference
Section (see "Grounding Method" on page 50) for specific information on proper
grounding techniques.
y
What type of building material is used? Make sure you have the appropriate drills,
drill bits and fasteners for dealing with a multitude of materials.
