This chapter describes how to install each unit and optical cables, along with power cabling method. In detail, the chapter describes how to install shelves or enclosuers of each unit, Power Cabling method and Optic Cabling and RF Interface. Furthermore, by showing power consumption of modules to be installed in each unit, it presents Power Cabling budget in a simple way. Then, it describes the quantity of components of modules to be installed in each unit and expansion method. 5.1 BIU Installation 5.1.
to combine and divide TX/RX signals, MPSU to supply devices with power, MCPU to inquire and control state of each module and Power Cable to supply power from external rectifiers. In addition, MDBU can be inserted and removed to provide services for desired band (Optional). 5.1.2 BIU Power Cabling BIU has -48V of input power. This unit should connect DC cable with the Terminal Block seen at the rear of BIU.
Note that BIU does not operate if the "+" terminal and the "–" terminal of the -48V power are not inserted into the accurate polarity. When you connect -48V power with BIU, use the ON/OFF switch of MPSU located at the front of BIU to check the power.

The name of all the ports are silk printed as "#1, #2, #3 and #4.
Through spectrum, you need to check signals sent from BTS TX. If the signals exceed input range (-20dBm~+10dBm), you can connect an attenuator ahead of the input port to put the signals in the input range. BIU interface with Bi-Directional Amplifier Basically, BIU is in Simplexer type; when you use BDA, you need to separate BDA signals from TX and RX type. Using a duplexer or a circulator, you can separate TX/RX signals of an external device from each other. Figure 5.
Figure 5.3 – 800PS BDA Interface using Duplexer BIU interfaces with BDA in either of the methods above. In this case, you need to check TX input range as well. Given the TX input range (-20dBm~+10dBm/Total per port), make sure to see if the value is in the input range, using Spectrum Analyzer, when you connect input ports.
5.1.4 MDBU insertion MDBU is designed to let a MDBU be inserted into any slot. BIU can be equipped with a total of four MDBUs. If only one MDBU is inserted into a slot with the other slots reserved, you need to insert BLANK cards into the other slots. If you do not terminate input and output ports of MCDU, which combines TX signals and divides RX signals, it will cause loss and generation of spurious signals at the other party's band. Given this, make sure to insert MDBU BLANK into slots of MDBU.
level of TX input and RX output signals in current service without affecting main signals. TX MON is -20dB compared with TX Input power and RX MON is -20dB as well compared with RX Output power. 5.1.5 ODU Interface BIU supports up to four ODUs. At the rear of BIU, eight RF input and output ports for ODU and four power ports for power supply and communication are provided. At BIU, you can check installation information of ODU.
If ODU is not connected in the right order, related devices may fail to communicate with each other or the unit may read wrong information. Given this, you need to connect the unit with accurate RF Port and Signal Port in a corresponding number. For unused RF Ports for ODU expansion, make sure to terminate them using SMA Term. When you put ODU on the top of BIU, it is recommended to install the unit at least 1U apart from BIU. Heat from BIU climbes up to reach ODU. 5.1.

Therefore, when you want to calculate total power consumption of BIU, you need to add power consumption of ODU to the total value. Power consumption of ODU is given in the later paragraph describing ODU. 5.
When you connect 2-column, 15-pin D-SUB Signal cable from BIU and install DOU, LED on the front panel is lit. Through this LED, you can check state values of LD and PD of DOU. 5.2.3 ODU Optic Cabling As optical module shelf, ODU makes electronic-optical conversion of TX signals and then makes optical-electronic conversion of RX signals. ODU can be equipped with up to two DOUs. One DOU supports four optical ports and one optical port can be connected with ROU.
The following figure shows installation diagram of ODU with two DOUs inserted in it. When you insert DOU into ODU, insert the unit into the left DOU1 slot first. Into unused slot, you need to insert BLANK UNIT in any case. 5.2.5 Consumption Power of ODU ODU gets power from BIU. One ODU can be equipped with up to two DOUs. Depending on how many DOUs are installed, power consumption varies.
5.3 ROU Installation 5.3.1 ROU Enclosure installation ROU is designed to be water- and dirt-proof. The unit has the structure of One-Body enclosure. It satisfies water-proof and quake-proof standards equivalent of NEMA4. ROU can be mounted into either of a 19” Standard Rack or on a Wall. Basically, ROU has both of a Wall Mount Bracket and a Rack Mount Bracket. Depending on the use of the Rack Mount Bracket, the bracket can be removed.
Figure 5.6 – Dimension used to install ROU on the WALL ROU Wall Mount Installation Turn M12 Fixing Screws by half on the wall and fully fix the screw with a Wall Mount Bracket on it. For convenience, the Wall Mount Bracket has fixing holes to let you easily mount an enclosure. Turn the M5 Wrench Bolt by half at each side of the Heatsink of the enclosure.
Put the enclosure with the M5 Wrench Bolt fixed on the fixing groove and fix the M5 Wrench Bolts into the remaining fixing holes. In this case, you will use 12 M5 Wrench Bolts in total except bolts used for the fixing groove. ROU Rack Mount Installation Like other units, ROU is designed to be inserted into a rack. The unit occupies around 13U of space except cable connection.
ROU component ROU has the following components: No.
to supply required power. In addition, RDU can be inserted and removed to provide service for desired band (Optional). 5.3.2 ROU Power Cabling ROU supports both of DC-48V and AC120V of input power. As RPSU for DC-48 and RPSU for AC120V are separated from each other, you need to select one of them in case of purchase order. RPSU for DC -48V and RSPU for AC 120V have the same configuration and capacity while each of the units uses different input voltage from each other.

ROU has one optical module in it.
Optical cables should be inserted into Optic Port outside of ROU. Using an optical slack devices in ROU, you need to coil around one or two roll of cables to be connected with the optical adaptor of ROPTIC. At this time, curvature of the optical cable should be at least 10Ø to prevent insertion loss from being increased. Through GUI, check if PD value of ROPTIC is in a tolerable range (+4~-1dBm). 5.3.
5.3.5 Coaxial cable and Antenna Connection - The coaxial cables which are connected to antenna distribued network connect to antenna port of ROU. Before connection, check the VSWR value of coaxial cable whether it is within specification using SITEMASTER . - At this time, check if the Return loss have above 15Db or VSWR have below 1.
