“…In general, these schemes can be classified by the downstream data format such as differential phase shift keying (DPSK) [3,4], frequency shift keying (FSK) [5], optical carrier suppression and separation (OCSS) [6], and inverse-return-to-zero (IRZ) [7], and so on. Since all the schemes re-modulate the downstream signal that with the constant optical power [8].…”

A novel passive optical network (PON) over optical code division multiple access (OCDMA) uplink based on the differential quadrature reference phase shift keying (DQPSK)/ on-off Keying (OOK) orthogonal re-modulation and time domain phase coherent OCDMA en/decoder scheme has been proposed. The bit error rate and receiver sensitivity of the system have been investigated, and the security performance and MAI (Multi Access Interference) property of the OCDMA uplink data have also been investigated. The results show that the proposed PON system is more cost-effective with less power penalty, and the capacity and security of upstream data can be greatly improved .
