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.
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.
You can insert a RDU into any slot. It is not possible to provide services with a RDU module alone; you need to connect the module with Cavity BPF in any case.

You cannot insert the same module and band into MULTIPLEXER port at the same time. For example, you are not supposed to insert both of 800PS RDU and 800PS+900I+PA RDU into ROU at the same time. In the same way, you cannot concurrently insert both of 850C RDU , 850C+700PS RDU and 850C+700LTEC into ROU. Information of LED at the front RDU RDU has the structure of enabling a random RDU to be inserted into three slots. ROU can be equipped with a total of three RDUs.
and the other slots ramian reserved, you need to insert BLANK cards into the other slots. When RDU is inserted into ROU, LED of the front panel shows the following information: LED Description Power is not supplied ON Power is supplied.
Up to three RDUs can be inserted. If one or two units of them are used, then you need to terminate the unused slot of RDU with a BLANK card. 5.3.

Depending on the quantity of each RDU, you can add overall power consumption of ROU. Only, in case of Dual-Band signals, power consumption is calculated respectively when HPA of the other party is turned OFF and two HPA devices are turned ON.
5.4.2 OEU Power Cabling The input power of OEU is DC -48V. You need to connect DC cable with the Terminal Block seen at the rear of OEU. Terminal -48V NC GND Color of cable Blue color Description Remark Input range: -42 ~ -56Vdc Not Connected Black color 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.
Note that OEU does not operate if the “+” terminal and the “–“ terminal of the -48V power are not inserted into the accurate polarity. 5.4.3 OEU Optic Cabling OEU is connected with upper ODU. With DOU inserted in it, the unit is connected with ROU. As OEU has a shelf with EWDM in it, the unit makes electronic-optical conversion of TX signals from ODU and makes optical-electronic conversion of RX signals. In addition, OEU can be equipped with up to two DOUs.
marred with dirt, it should be covered with a cap during move. When devices are connected through optical cables, you need to clear them using alcohocol to remove dirt. 5.4.4 Insert DOU to OEU Into OEU Shelf, up to two DOUs can be inserted. DOU module is in Plug in Play type. When you insert DOU in OEU, insert the unit into the top DOU1 slot first. You can be careful as the number is silk printed at the left. The following figure shows installation diagram of OEU with one DOU inserted in it.
