| Passive optical networks (PONs) are a promising economic solution in delivering data to the end-user. We demonstrate experimentally the uplink of a spectral-amplitude-coded optical code division multiple access (SAC-OCDMA) and an optical time division multiple access (OTDMA) PON, with burst-mode reception. The receiver performs clock and data recovery (CDR), phase acquisition and forward-error-correction (FEC).;Using FEC we demonstrate an error-free 7x622 Mbps uplink of an incoherent SAC-OCDMA PON, while operating at a relatively low power of around -24 dBm. In going to from a back-to-back architecture to a local sources PON configuration the penalty introduced is less than 1 dB.;We show that the burst-mode functionality of the receiver enables instantaneous phase acquisition and zero packet loss. However, it introduces a power penalty of around 1dB, which is the price to pay to accommodate bursty traffic and achieve instantaneous phase acquisition using zero bits of preamble. |
