This letter presents a novel technique that enables simple provisioning of independent services in wavelength-division-multiplexed passive optical networks. The technique uses a single laser and modulator for generation and a periodic passive filter for separation of two closely separated baseband channels. We present experimental results of the bit-error-rate performance for the two 1.5-Gb/s independent service channels at a frequency separation of only 6 GHz. © 2007, IEEE. All rights reserved.
