With an optic splitter in it, this unit divides optical signals from Laser Diode into four and then distributes them to each optical port. With a total of four Photo Diodes in RX, DOU makes optical-electronic conversion of signals received from each optical port. In addition, the unit is equipped with ATT for optical compensation made in case of optical cable loss. With internal WDM, it uses only one optical cable to be connected with ROU. Figure 4.11 β MDBU Outer Look 2) 2Way Divider (2W) 2W is equipped with two 2-way splitters in a one-module form and the splitters work for TX/RX signals, respectively. Designed in broadband type, the divider combines and divides 2GHz or higher of signals from FSK modem signals.

In this case, it is recommended to stack the units at least 1U of an interval between BIU, for heat from BIU may climb up to ODU, which may cause flame. As seen in the figure below, connect the coaxial cable for TX and another coaxial cable for RX with corresponding ports at the rear of BIU. For power supply and communication, connect 15Pin D-Sub Connector cable with a corresponding port. Confidential & Proprietary 37/99 4.3 OEU (Optic Expansion Unit) OEU is mainly used to remotely deliver signals for Campus clusters. At the upper part, this unit combines with ODU and receives TX optical signals to convert them into RF signals. Then, it regenerates the signals to secure S/N feature and converts them into optical signals. The signals are sent to ROU through optical cables. When it receives RX optical signals from ROU, the unit converts them into RF signals to regenerate the signals and then converts them into optical signals to send them to ODU. In OEU, one shelf can be equipped with up to two DOUs. The DOU is the same as the module used for ODU. Up to two OEUs can be connected with ODU.

Confidential & Proprietary 63/99 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. 5.1.6 Consumption Power of BIU The table below shows power consumption of BIU: PartUnitConsumption PowerRemark Shelf MCDU MCPU Common Part MPSU 7.5 W MDBU 800PS 12W MDBU 800PS+900I+Paging 20W MDBU 850C 12W MDBU 850C+700PS 19W MDBU 1900P 20W MDBU MDBU AWS-1 12W BIU supplies power for ODU. 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. Confidential & Proprietary 64/99 5.2 ODU Installation ODU should be, in any case, put on the top of BIU.
