Effectiveness of SIEPON package B compliant ONU sleep technique and impact on latency and transmission efficiency from a theoretical point of view

We report the power-saving effectiveness of an optical network unit (ONU) sleep technique by performing numerical calculations using an ONU sleep simulator that we developed, which complies with the IEEE Std 1904.1 (SIEPON) Package B. We reveal that reducing the transmission interval of GATE messages to about 10 ms is effective in securing both power-efficiency and low-latency characteristics when an early wakeup function is implemented.
