Abstract
A spectral amplitude coded-optical code division multiplexing time division
multiplexing (SAC-OCDM/TDM) passive optical network (PON) for upgrading the
traditional TDM PON is proposed. To the best of our knowledge, our work is the first
to report on the use of both spectral and orthogonal code domains, which are
transparent to optical network unit (ONU) for hybrid PON, in order to upgrade TDM
PON seamlessly. The fewer encoder/decoders and cheaper optical source under the
conditions of high bite rate and large ONU accommodation make the system
cost-effective. A downstream experiment is demonstrated, and the results demonstrate
that the proposed system is feasible.
