IEEE/ICACT20210174 Question.4 Questioner: Yiile@outlook.com 2021-02-10 오전 10:50:19	IEEE/ICACT20210174 Answer.4 Answer by Auhor nurazmina.lingas@utb.edu.bn 2021-02-10 오전 10:50:19
Hello, what are the characteristics of the sleep mode optical network unit?	ONU sleep mechanisms periodically turn ONU transmitter components off to reduce unnecessary energy consumption. Although ONU sleep mechanisms can greatly improve the situation in that aspect, they also introduce additional delay and enlarge the latency of the connection. When the ONU has traffic to send or receive, it is in active mode, otherwise, it is in sleep mode. When the ONU is an active mode, it can send or receive data traffic but consumes more energy. Whilst the ONU is in sleep mode, it consumes much less energy but cannot receive any downstream traffic transmitted by OLT. Therefore, the sleep period should be carefully assigned in order to avoid missing any incoming packets.
