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.
5.2 ODU Installation ODU should be, in any case, put on the top of BIU. This unit gets required power and RF signals from BIU. The following table shows components of ODU: No. Unit Common Part Optional Part 5.2.1 Description Remark Shelf Including Main Board, 19”,1U 1EA RF Cable SMA(F) to SMA(F), 400mm 2EA Signal Cable 2Row(15P_F) to 2Row(15P_M),650mm 1EA DOU Optical Module with 4 Optic Port Up to 2EA to be inserted ODU Shelf Installation ODU is a shelf in around 1U size.
Figure 5.4 – Optical cable of SC/ACP Type For optical adaptor, SC/APC type should be used. To prevent the optical access part from being 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. 5.2.4 Insert DOU to ODU In an ODU Shelf, up to two DOUs can be installed. DOU module is in Plug in Play type. When you insert DOU in ODU, insert the unit into the left DOU1 slot first.
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. The table below shows power consumption of ODU: Part Unit Consumption Power ODU_4 DOU 1 EA 13W ODU_8 DOU 2 EA 26W Remark 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.
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). 5.3.4 Insertion of RDU ROU has slots to enable up to three RDU modules to be inserted into the unit.
