4.2 ODU (Optic distribution Unit)
ODU receives TX RF signals from upper BIU and converts them into optical signals. The optical
signals are sent to ROU through optical cables. This unit converts optical signals from ROU into
RF signals and sends the converted signals to BIU.
For each shelf of the ODU, up to two DOUs (Donor Optic Unit) can be installed in it.
One DOU is supported with four optical ports. Therefore, one ODU can be connected with eight
ROUs.
Up to four ODUs can be connected with BIU.
