1.4.10 Determine Site Equipment Location and Requirements
Site equipment can be installed in a free-standing rack or wall-mounted cabinet. Triton Network
Systems recommends a lockable cabinet for maximum physical security. A site equipment
cabinet typically contains the power source for an IFU and is the primary cable termination point
for the power, GPI, and fiber optic cables that are connected to an IFU.
It is possible to mount the site equipment indoors or outdoors. It is preferable to mount the site
equipment in a room (such as an electrical room or a telecommunications closet) close to the IFU
location.
When determining the location for a site equipment cabinet or rack, observe the following:
Identify the riser and the horizontal cable runs from the entry point to the site equipment
room.
Ensure that there is sufficient clearance to allow a technician to access the site equipment.
Ensure that the site equipment location meets the minimum environmental specifications for
all equipment to be located in the site equipment cabinet or rack.
1.4.11 Determine the Length of Fiber Cable Assemblies
The primary consideration for selecting an outdoor cabling option is the distance and route
between an IFU and the site equipment.
A single Triton Network Systems outdoor fiber cable assembly can connect an IFU directly to
the site equipment when the cable run required for this connection (see Figure 1-1). If the cabling
distance between the IFUs and the customer premise equipment (CPE) exceeds the maximum
length of the longest available Triton Network Systems outdoor fiber cable assembly, the
customer has the following options:
Order outdoor fiber cable assemblies from Triton Network Systems and acquire the
following additional items (see Figure 1-2):
ß
A demarcation box, which provides a connection point for two IFUs installed on the
same rooftop.
ß
An indoor fiber cable of sufficient length to connect the demarcation box to the site
equipment.
NOTE: Contact your Triton Network Systems sales representative for available lengths of
prefabricated outdoor fiber cable assemblies.
NOTE: For sites without a demarcation box, back-to-back connections between IFUs on the
same rooftop are made through a fiber patch panel located with the site equipment. Otherwise,
the demarcation box provides the back-to-back IFU connection.
