Abstract :
A hybrid analog and digital passive optical network based on optical code division multiple access is presented, and a code generation method is proposed to increase the number of codes for existing code families with fixed and ideal in-phase cross correlations. When code families with cyclic properties are used by this code generation method, compact encoders based on arrayed waveguide gratings can be used. The corresponding performance for this hybrid network is also analyzed.
