2.1.3.3 Remote Optic(ROPTIC)
Remote Optic converts optical signals into RF signals and performs vice versa. It also has internal ATT for
optical compensation to compensate for optical cable loss. It provides two path in pairs(TX/RX) to
transport RF signal to ARUs.

2.1.3.4 Remote Central Processor Unit (RCPU)
RCPU can monitor and control each module of HROU. This unit receives and analyzes upper
communication data from Remote Optic and reports the unit's own value to upper devices. At the front
of the module, it has LED indicator to show system status, letting you check any abnormalities at a time.
