ODU Power Consumption
Because the BIU provides power to the ODU(s), power requirements for the DOUs are included in the
BIU power budget. The power supply provided for the BIU has factored in the max load for the system,
but for your information, the each Donor Optic Unit (DOU) in the ODU consumes 14 Watts, meaning a
fully loaded DOU consumes 28 Watts.

Installing DOUs
A maximum of two DOUs can be installed in each ODU chassis. The required number of DOUs for each
ODU is installed at the SOLiD facility based on the configuration you ordered. SOLiD also installs blank
cards in unused DOU slots. You can expand or upgrade the DAS system at any time by installing
additional DOUs or removing existing units.
For proper operation, the first DOU in the ODU should occupy the “DOU 1” slot, while a blank plate
should cover the unused slot. The following figure shows the ODU with both configurations.
