Abstract

We simulated and investigated the performance of optical overlay of two multicast and a unicast data on a wavelength division multiplexed passive optical network using intensity and minimum shift keying modulation. In an optical line terminal (OLT), three optical subcarriers are generated from a single sinusoidal clock to carry two independent 10-Gbps multicast data and one 10-Gbps unicast data through dispersion-shifted fiber. At the same time, another 10-Gbps data are remodulated and transmitted back to the OLT. Error-free transmission is achieved and almost the same power penalty is observed for the downstream unicast as well as the remodulated upstream data irrespective of whether either one or both of the multicast data are enabled or disabled.
