Abstract :
Cost effectiveness and energy efficiency have recently become two practical issues during access networks construction and operation. In this paper, we extend our previous proposal of a remote channel combine/split module for long-reach wavelength division multiplexed and time division multiplexed passive optical network systems. Besides previously discussed benefits on investment cost and energy efficiency under take-up-rate-adaptive mode, this study shows that proposed systems help achieve higher energy saving by adopting traffic-adaptive power management. Simulation results show up to 35% power consumption saving at the time of minimum traffic demands. Moreover, in terms of energy consumption over periodic time, we find a typical 20% energy saving can be achieved compared to conventional systems in fully operated stage.
