4.2.6 Interface with BIU
Figure 4.15 – Interface between BIU and ODU
On the top of BIU, up to four ODUs can be stacked.
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.
