3.5 Installation Conventions
Some of the basic installation conventions are listed below for the MA 2000 system:
• Base Units – are usually concentrated in the same location, most often in the main
communication room.
• Remote Cabinet (or 2000 Lite) – usually placed in the communication shaft or closet
of a corresponding floor so they can be easily located. Each cabinet (or 2000 Lite) can
typically cover a floor of up to 30,000 sq ft.
• Fiber optic cable - bundled fibers are terminated into the Base Units in the main
communication room. The fibers are then routed to each coverage locations where
individual fibers terminate into splice boxes. The splice box couples the installed fiber
into the remote units. Enough spare fibers should be installed to take into account
future expansion of the system.
For example, for three remote units, six fibers are required. However, to allow for future
upgrades, it is recommended to install additional optic fibers to be connected to additional
RUs.
