Confidential & Proprietary 44/99 4.4 ROU (Remote Optic Unit) ROU receives TX optical signals from ODU or OEU and converts them into RF signals. The converted RF signals are amplified through High Power Amp in a corresponding RDU, combined with Multiplexer module and then radiated to the antenna port. When receiving RX signals through the antenna port, this unit filters out-of-band signals in a corresponding RDU and sends the results to Remote Optic Module to make electronic-optical conversion of them. After converted, the signals are sent to a upper device of ODU or OEU. ROU can be equipped with up to three RDUs (Remote Drive Unit) and the module is composed of maximal Dual Band. Figure 4.25 – ROU Outer Look ROU is designed in a cabinet, and provides the following functions and features. 4.4.1 Specifications of ROU Item Spec.

This unit is divided into DC/DC type to output +6V, +9V and +27V of DC power and AC/DC type to receive 120V of AC input and to output +6V, +9V and +27V of DC power. Upon order, either of the two types should be decided. MS Connector, which uses ports to receive inputs, is designed to accept any of AC and DC. Only in this case, the input cable is different.RPSU has a circuit brake to turn the power ON/OFF and has LED indicator at the top to check if input power is normally supplied. 850C850C+700PS 1900P+AWS-1VHF+UHF
Confidential & Proprietary 49/99 3) Remote Optic(R OPTIC) Remote Optic converts optical signals into RF signals and performs vice versa. With an FSK modem in it, the unit communicates with upper devices. It also has internal ATT for optical compensation to compensate for optical cable loss, if any. Figure 4.28 – R OPTIC Outer Look 4) Remote Central Processor Unit (RCPU) RCPU can monitor and control each module of ROU. This unit receives and analyzes upper communication data from Remote Optic and reports the unit's own value to upper devices. At the front of the module, it has LED indicator to show system status, letting you check any abnormalities at a time. At the same front, it also has communication LED Indicators to show communication status with upper devices. Through RS-232C Serial Port, the unit enables you to

Confidential & Proprietary 54/99 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 5.1.1 BIU Shelf Installation Generally, BIU is inserted into a 19” Standard Rack. As this unit has handles at each side for easy move. With two fixing holes at each side, you can tightly fix the unit into a 19” rack. Figure 5.1 – RACK Installation BIU has the following components: No. Unit Description Remark Shelf Including Main Board, 19”,5U 1EA MCDU - 1EA MCPU With Ethernet Port and RS-232 Port 1EAMPSU Operate -48Vdc Input 1EA Common Part Power Cable -48Vdc Input with two lug terminal 1EA Optional Part MDBU 800PS,800PS+900I+Paging,850C,850C+700PS, 1900P, AWS-1 MDBU Up to 4EA to be inserted Basically, the common part of BIU should have shelves and it should be equipped with MCDU
Confidential & Proprietary 55/99 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. Terminal Color of cable Description Remark -48V Blue color - GND Black color - NC Not Connected - Before connecting the power terminal, you need to connect "+" terminal of Multi Voltage Meter probe with the GND terminal and then connect "–" terminal with -48V to see if “-48Vdc” voltage is measured. After the check, you need to connect the power terminal with the terminal of the terminal block seen below.
Confidential & Proprietary 56/99 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. 5.1.3 RF Interface at BIU BIU can be connected with Bi-Directional Amplifier and Base Station Tranceiver. To connect BIU with BDA, you need to use a duplexer or a circulator to separate TX/RX signals from each other. BIU can feed external TX/RX signals from the Back Plane. Using MDBU separated from each carrier band, BIU can easily expand and interface with bands. As seen in the table below, MDBU is divided into Single and Dual Bands. The unit can be connected with two to four carrier signals per band. At the rear, #1~4 marks are seen in order per MDBU. The following table shows signals to be fed to corresponding ports: No Unit naming Description In/out RF Port Power Switch LED Description Abnormal, Not supply Power -48Vdc ON Normal supply power -48Vdc Normal Status ODC ALM Failure of output Power ON IDC ALM Normal Status

The name of all the ports are silk printed as "#1, #2, #3 and #4." Referring to the table above, you need to feed right signals to input and output ports of corresponding MDBU. For each port, TX signals and RX signals are separated from each other. You don't have to terminate unused ports unless you want to. BIU interface with Base station Transceiver Basically, BIU has different TX and RX ports, and so, you have only to connect input and output ports.
Confidential & Proprietary 59/99 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 5.2 – 800PS BDA Interface using Circulator
Confidential & Proprietary 60/99 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 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. When MDBU is inserted into BIU, LED at the front panel will show the following information:
Confidential & Proprietary 61/99 MONITOR SMA port seen at the front panel of MDBU enables you to check current 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. LED Description Power is not supplied. ON Power is supplied. Normal Operation ALMAbnormal Operation
Confidential & Proprietary 62/99 At the rear part of ODU, the number of RF Ports and Signal Ports are printed in order. Therefore, you need to be careful in case of expansion of ODU. RF Port ODU Numbering TX RXSignal Port ODU 1 #1 ODU-1 ODU 2 #2 ODU-2 ODU 3 #3 ODU-3 ODU 4 #4 ODU-4
