  Increasing capacity demands in the access networks require inventive concepts
for the transmission and distribution of digital as well as analog signals over
the same network. Here a new transceiver system, which is completely agnostic
for the signals to be transmitted is presented. Nyquist sampling and time
multiplexing of N phase and intensity modulated digital and analog channels
with one single modulator, as well as the transmission and demultiplexing with
another modulator have been demonstrated. The aggregate symbol rate corresponds
to the modulator bandwidth and can be further increased by a modification of
the setup. No high-speed electronic signal processing or high bandwidth
photonics is required. Apart from its simplicity and the possibility to process
high bandwidth signals with low bandwidth electronics and photonics, the method
has the potential to be easily integrated into any platform and thus, might be
a solution for the increasing data rates in future access networks.
