We propose a novel and simple coding device for centralized monitoring of passive optical networks. Encoders have dual Bragg gratings forming a cavity producing periodic codes. These encoders reduce the cost of manufacturing, installation, inventory, and operation, while maintaining good performance and high capacity. We evaluate monitoring efficiency in terms of signal-to-noise ratio.
