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. However, the two paths for transmission to ARU are not used in MPROU.
