ODU Specifications
The ODU mounts in a standard 19-inch rack frame and occupies one rack unit (1U). The ODU is
generally co-located with the BIU from which it receives power and RF communication. Two coax cables
and a power supply cable connect the two units. Up to eight ODUs can be connected with the BIU, four
for the SISO and four for the MIMO paths. Each ODU can hold two Donor Optic Units, and each DOU
supports four optical ports. Therefore, each ODU can provide connections to eight MRUs (or six MRUs
and two OEUs).
