Guidelines for Connecting Outdoor Fiber Cable Assemblies
Providers can either directly connect outdoor cables to the site equipment or interface to the site
equipment through an intermediary connection point such as a demarcation box. The following
subparagraphs provide guidelines for choosing the appropriate option.
Direct Fiber Connection (Options 1 and 2)
Use a single outdoor fiber cable assembly when the cable run between the IFU and the site
equipment interface (switch, ADM, or fiber patch panel) is less than the maximum length of the
longest available Triton Network Systems outdoor fiber cable assembly. The two single fiber
connection options are as follows:
• Riser-rated cable (Option 1). This option uses a single riser-rated plenum fiber cable to
connect directly to the site equipment interface without the use of conduit or a demarcation
box. Use Option 1 when the site engineering plan specifies that the IFU fiber cable will be
installed within building riser assemblies (see Figure 1-1 A).
