In an RN configuration for providing a new service in a PON according to the present invention, it is possible to configure the RN remotely by instantaneous powering from a remote site only when necessary, while the RN being operated as a PON at ordinary times. More specifically, an RN configuration for providing a new service in a PON according to the present invention includes a power generation block capable of providing energy necessary for activating the RN by instantaneously supplied power from the remote site. Further, an RN according to the present invention further includes either one or both of a control agent block capable of controlling and managing optical paths of the RN by using power generated from the power generation block; and a reconfigurable switching block capable of configuring and switching the optical path of the RN through the power being provided from the power generation block and a control by the control agent block.
