Donor Optic Unit (DOU)
DOU makes electronic-
optical conversion of TX signals and makes optical
of RX signals.
With an optic splitter in it, this unit divides optical signals from Laser Diode into four and then
distributes them to each optical port. With a total of four Photo Diodes in RX, DOU makes
optical-
electronic conversion of signals received from ea
equipped with ATT for optical compensation made in case of optical cable loss.
With internal WDM, it uses only one optical cable to be connected with ROU.
