3.2 Hardware Structure

The OptiX RTN 600 hardware consists of IDU and ODU. The ODU is connected to the
IDU through a coaxial cable. The cable is used to transmit IF signals, O&M signals,
and -48 V DC power.

3.2.1 IDU

The IDU is the indoor unit of an OptiX RTN 600 system. It accesses services, and
performs multiplexing/demultiplexing and IF processing of the services.
The IDU is designed with slots. You can install different types of boards into the slots
to realize different functions.
