Abstract
High data rates applications are the current demand of data communication networks which uses optical fibers as a backbone network. This demand has raised the power consumption of optical network units in passive optical networks (PONs). So cyclic sleep techniques in PONs can save the energy consumption during idle slots and low traffic conditions. In the proposed paper cyclic sleep is implemented at the ONU with the help of a single-drive MZM placed after Gaussian filter in every channel because of less energy feature and high bandwidth objective. MZM is being driven by a low-frequency NRZ/PRBS control signal. The results shown in this paper well represents less power consumption using cyclic sleep which results in more energy efficiency to improve the power savings. In the proposed paper cyclic sleep is implemented at the ONU with the help of a single-drive MZM placed after Gaussian filter in every channel. With taking the assumed values of power, the estimated average ONU electrical power is 1.1 W, corresponding to ∼45 % electrical energy saving.
