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
opt
ical 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.
