Abstract.  We propose and experimentally demonstrate a multicast-enabled survivable architecture for wavelength-division-multiplexed passive optical networks. By manipulating the sinusoidal control clock and the wavelength of the light source for each downstream wavelength channel at the optical line terminal, different optical subcarriers are generated to provide subscribers with not only multicast data transmission but also survivability against fiber failure in either distribution or feeder fibers. The simultaneous transmissions of 10-Gb/s unicast data and 10-Gb/s multicast data under normal working mode, as well as the 10-Gb/s transmissions for unicast data under protection mode, are experimentally demonstrated.
