Component of HERCULES Remote Unit
Remote Unit receives TX optical signals from Head-End and converts them into RF signals. The converted
RF signals are amplified through High Power Amp in a corresponding RDU, combined with Multiplexer
module and then radiated to the antenna port.
When receiving RX signals through the antenna port, this unit filters out-of-band signals in a corresponding
RDU and sends the results to Remote Optic Module to make electronic-optical conversion of them. After
converted, the signals are sent to a upper device of ODU. ROU can be equipped with up to six RDUs
(Remote Drive Unit). The following table describes components on Remote Unit
