To ODU Interface (N-Type Connector)
The
TO ODU
interface (N-type connector) is the IDU-side IF connection between the IDU and ODU. The
IDU transmits payload data to the ODU on a 280 MHz carrier and receives the ODU data on a 140 MHz
carrier. The IF connection also provides a full-duplex control and monitoring channel between the IDU and
ODU on a 4.5 MHz carrier. Additionally, this interface provides DC power to the ODU, taken directly
from the voltage supplied to the power connection on the rear of the IDU. The power supply is protected
from a short-circuit on the IDU/ODU connection via a thermal protection device.
