Revision 15-01
The Fiber-DAS system consists of two major parts; Master Unit and Remote Unit. The Master Unit
(MU) and one or more Remote Units (RU) are connected to each other using optical fiber link.
3.3 Master Unit
The Master Unit consists of a 19 inch frame rack with modules that are selected depending on the
system design. Generally all Master Units contains a power supply, at least one Base Station Interface
Unit (BIU), an RF splitter/combiner unit called the Point of Interconnect (POI) and minimum one
Fiber-Optic Interface card (FOI).
3.3.1 MFU – Master Frame Unit
The Master Frame Unit houses the other modules such as power supplies, fiber-optic interface cards
and base station interface units.
Figure 8: Master Unit
The frame in the picture shows a frame equipped with 3 base station interface units, 6 fiber-optic
interface cards and one power supply (as just an example).
Functional description
One frame supports several modules which can be placed anywhere in the frame as well as a
combination of several different types of units in a frame. There are 16U positions in the frame that
can be utilized. The modules have different widths which can be found in each module’s
specifications in the following sections of this manual.
This means that one shelf can house up to 4 power supplies or 8 base station interface cards or up to
16 fiber-optic interface cards. Each frame needs at least one power supply, but they do not
necessarily have to be placed in the frame that they power. Quite often a system has more than one
power supply and they are usually placed together in one frame for easy access.
Each frame has two Molex connectors that can be connected to a power supply. This allows for a
primary and a redundant power supply to be connected to it to ensure operation even if one power
supply should fail.
