You can use fiber repeaters for these tasks:
• Extend the total length of your segment (point-to-point or
trunk line topology)
• Create star and ring configurations (multiple directions from one point)
• Cross into hazardous areas
When you configure your network by using fiber repeaters, you can install them
in one of the following ways:
ATTENTION: In hazardous areas, you must use products
specifically designed for that purpose. You can use fiber repeaters
that are designed for hazardous areas as a link from your
non-hazardous area to your hazardous area.
For hazardous locations, consult the ControlNet EX Media Planning
and Installation Manual, publication
CNET-IN003 .
