Modem Unit (IDU)

Assembly

The indoor half: a modem ASIC modulates traffic at up to 4096-QAM with adaptive coding, an Ethernet switch aggregates the payload, and the unit feeds the ODU over a single coax carrying IF, management, and power. A full specification article for this item is being written. Meanwhile its bill of materials and connections are below.
