“Only qualified personnel should handle the DAS equipment. Any person involved in installation or service of the DAS should understand and follow these safety guidelines.” -The head end unit must always be connected to the Base Station using a direct cabled connection. This system has not been approved for use with a wireless connection via server antenna to the base station.
users. This power reduction is to be by means of input power or gain reduction and not by an attenuator at the output of the device." - The power of this system shall be supplied through wiring installed in a normal building. If powered directly from the mains distribution system, it shall be used additional protection, such as overvoltage protection device - Only 50 ohm rated antennas, cables and passive equipment shall be used with this remote.

bands through one antenna. The system covers public and private venues such as: Shopping malls Hotels Campus areas Airports Clinics Subways Multi-use stadiums, convention centers, etc. The system enhances in-building radio environments that lack signal quality by improving the RSSI and Ec/Io. By providing communication services throughout the building, the system enables users to make a calls anywhere in the coverage area.
Compact design Upgradable design Easy installation and maintenance Adopts auto ID scheme The SC-DAS platform will serve two primary segments; first as a carrier deployed coverage enhancement product for their specific frequencies and second as a low cost, public safety / single carrier product.

Section3 ROU Installation This chapter describes how to install each unit and corresponding fiber cables, along with power cabling method. In detail, the chapter describes how to install shelves or enclosures of each unit, Power Cabling method , Optic Cabling and RF Interface. Furthermore, by showing power consumption of modules installed in each unit, a the Power Cabling budget is easily determined.
3.1 ROU Installation 3.1.1 ROU Enclosure installation The ROU enclosure has two options. One meets NEMA4 standard and the other is not waterproof or dirtproof. The ROU can be mounted on a Wall easily. Rack mounting is also possibleusing special frame. There are 3 different types and they will be explained later in this chapter. The ROU consists of anMRU and anARU. Their dimensions are thesame. The following shows the dimension of the mounting holes for the Wall Mount Bracket. Figure 3.
Figure 3.2 – ROU installation procedure side by side Place the enclosure with the M6 Bolt on the mounting groove and mount the M6 Wrench Bolts into the remaining mounting holes. In this case, you will use 4 M6 Wrench Bolts.
Figure 3.3 – ROU installation diagram side by side For connecting cables between MRU and ARU easily, the MRU should install on left side of ARU. Type2 : stacked installation If space prohibits the MRU and ARU from being mounted side by side, the units can be installed in a stacked configuration. Stacking the unit requires a special baracket for stacked installation First, install the MRU on the wall , then install the bracket for stacked installation on the MRU. Finally install the ARU on the bracket.
The following shows dimension of the mounting point for the stacked bracket. Figure 3.
ROU Rack Mount Installation There are two ways to install rack mount. One is to install ROUs on the rack vertically: the other is to install ROUs on the rack horizontally Type1 : Vertical installation on the rack For vertcal installation, a vertical bracket is needed. First, install bracket for vertical installation on the rack Second, mount MRU on the left side of the installed bracket Third, mount ARU on the right side of the installed bracket Completed installation diagram is as follows Figure 3.
Figure 3.7 – ROU installation diagram for vertical rack Type2 : Horizontal installation on the rack For Horizontal installation, horizontal bracket is needed.
Figure 3.8 – ROU installation procedure for horizontal rack The following shows dimensions of the mounting point for horizontal installation Figure 3.
3.1.2 ROU Power Cabling The ROU supports both of DC-48V and AC120V input power. The type of input power for the ROU is already determined at the factory. The ROU is shipped with the correct power cable in the package box. See the UL name plate of the ROU to determine the input power type of the ROU or see the power connector in the below picture. You should order the type of input power as your application. (a)AC/DC (b)DC/DC Figure 3.
3.1.3 Optical Cabling The MRU makes the optical-RF conversion of TX signals from upper the ODU and OEU as well as the RF- optical conversion of RX signals. The MRU has one optical module in it. As WDM is used in the R_OPT module, two separate wavelengths (TX:1310nm, RX:1550nm) can be sent/received with one fiber strand at the same time. The MRU has SC/APC connectors. To prevent the fiber interface from being marred with dirt, it should be covered with a cap when not installed.
Figure 3.12 – ROU GND Port view - Take off the GND terminal port from the enclosure and connect to the ground cable. Then reconnect it to the enclosure - The opposite end of the ground cable should connect to the communication GND of building - The ground lug is designed meeting the SQ5.5 standard 3.1.5 Coaxial cable and Antenna Connection - The coaxial cables which are connected to DAS connect to antenna port of the ROU.
