| Περίληψη: | The focus of this thesis is the Multi Parallel optical DAC component. The MPoDAC is
a component part of an optical transceiver. Optical transceivers are an integral part in
the function of a Data Center (DC). Today’s optical transceivers function based on an
electronic DAC accompanied by a DSP unit and drivers that increase the signals power
before it gets to the photodiodes. The problem with today’s DACs lies in the bandwidth
limitations of the DAC and the high energy consumption that the DSP unit introduces
to the component. oDACs are meant to replace the outdated electrical DACs, they offer
great bandwidth scalability and they do not require a DSP unit, thus making them much
more energy efficient. In this thesis the conventional architecture, the parallel oDAC
and the MPoDAC are directly compared in terms of energy efficiency and bit rate
scalability.
