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 Description Common Part Shelf RF Cable Signal Cable Including Main Board, 19,1U SMA(F) to SMA(F), 400mm 2Row(15P_F) to 2Row(15P_M),650mm Optional Part DOU Optical Module with 4 Optic Port Remark 1EA 2EA 1EA Up to 2EA to be inserted 5.2.1 ODU Shelf Installation ODU is a shelf in around 1U size. Its width is 19 and so this unit should be inserted into a 19 Standard Rack. ODU should be, in any case, put on the top of BIU. BIU should be distant around 1U when the unit is installed. 5.2.2 ODU Power Cabling ODU does not operate independently. The unit should get power from BIU. 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. Optionally, only optical port 4 can be connected with OEU. As WDM is installed in DOU, the unit can concurrently send and receive two pieces of wavelength (TX:1310nm, RX:1550nm) through one optical core. DOU has SC/APC of optical adaptor type. Confidential & Proprietary 61/87 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. You can be careful as the number is silk printed at the left. The following figure shows installation diagram of ODU with one DOU inserted in it. 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. Confidential & Proprietary 62/87 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 ODU_4 ODU_8 Unit DOU 1 EA DOU 2 EA Consumption Power Remark 13W 26W 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. The following shows dimension of the fixing point for the Wall Mount Bracket. Figure 5.5 How to install ROU Confidential & Proprietary 63/87 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. Confidential & Proprietary 64/87 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. Confidential & Proprietary 65/87 ROU component ROU has the following components:
No. Common Part Unit Enclosure RCPU R_OPTIC RPSU Multi-Plexer Power Cable Description Remark Including Rack & Wall cradle

It should have Power Cable for external rectifier or to supply required power. Confidential & Proprietary 66/87 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. The following figure shows configuration of RPSUs for DC -48V and AC 120V. Confidential & Proprietary 67/87 MC Connector numbering A B C Lug Naming RPSU Terminal naming AC AC_H AC_N GND DC

ROU has one optical module in it. As WDM is installed in the R_OPTIC module, two pieces of wavelength (TX:1310nm, RX:1550nm) can be sent/received with one optical core at the same time. ROU has SC/APC of optical adaptor type. For optical adaptor, SC/APC type can 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. Confidential & Proprietary 68/87 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 10 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. 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.
