A.usage of sleep mode:binary adaptation
An effective method to reduce the energy consumption in access networks is to implement sleep mode policies at the ONTs. Indeed, we estimated that the majority of the users is using their line connection for a limited amount of time during the day. This practice can significantly reduce the energy consumption at the user's side, but not at the operator's side. Indeed, since the OLT is shared between several ONTs, it is very unlikely that all the ONTs associated to a given OLT are idle.
