Abstract :
We propose an asynchronous gigabit-symmetric OCDMA-PON architecture in which ONUs are source-free. We also demonstrate a duplex OCDMA system with 50 km 10 Gbit/s/user 4-user DPSK-OCDMA downstream and 50 km 10 Gbit/s/user 4-user OOK-OCDMA upstream links. Error-free transmissions are achieved in the experiment.
