Abstract :
Optical CDMA is proposed to implement a PON that supports downstream native optical multicasting. Common wavelengths within provisioned 2D codes may uniquely represent a multicast group. We introduce a simple architecture enabling native 2D-OCDMA multicasting without resorting to code tunability. We outline the associated code-provisioning problem and demonstrate clear SIR advantages compared to 2D-OCDMA.
