This paper presents a solution for upgrading optical access networks by reusing existing electronics or optical equipment:
sliceable transponders using signal spectrum slicing and stitching back method after direct detection. This technique
allows transmission of wide bandwidth signals from the service provider (OLT - optical line terminal) to the end user
(ONU – optical network unit) over an optical distribution network (ODN) via low bandwidth equipment. We show
simulation and experimental results for duobinary signaling of 1 Gbit/s and 10 Gbit/s waveforms. The number of slices is
adjusted to match the lowest analog bandwidth of used electrical devices and scale from 2 slices to 10 slices. Results of
experimental transmission show error free signal recovery by using post forward error correction with 7% overhead.
