摘要： It is necessary to completely remove overlapping of signals between plural PONs in order to make the PONs coexist. Accordingly, it is required to share or intensively manage bandwidth use conditions over an optical fiber that serves as a common band between plural systems. Therefore, transmission clocks should be synchronized with high accuracy between plural systems. A reference clock is provided from an external device or a representative OLT to the entire systems to perform clock synchronization between plural systems, so that the overall systems are synchronized by synchronizing each OLT with the reference clock. A hierarchical management method is selected that manages ONUs under the control of each OLT by managing band use information arranged for each OLT with respect to an external device or a representative OLT for sharing of bandwidth use conditions between plural systems.
摘要翻译：为了使PON共存，必须完全消除多个PON之间的信号重叠。因此，需要在用作多个系统之间的公共频带的光纤上共享或集中管理带宽使用条件。因此，传输时钟应该在多个系统之间以高精度同步。从外部设备或代表性OLT向整个系统提供参考时钟以在多个系统之间执行时钟同步，使得通过使每个OLT与参考时钟同步来使整个系统同步。选择分级管理方法，通过管理针对每个OLT针对外部设备或代表性的OLT布置的用于共享多个系统之间的带宽使用条件的代表性OLT来管理在每个OLT的控制下的ONU。

摘要： Provided is an ONU that suppresses transmission of a useless multicast control message to a PON section and enables a communication bandwidth of the PON section to be effectively used. The ONU of the PON system has a multicast group management table that shows a correspondence between a multicast group identifier and an address of a user terminal participating in a multicast group. When the ONU receives a request message of participation in the multicast group from the user terminal, the ONU registers the correspondence between the multicast group identifier indicated by the received message and the user terminal address. A new received message is deleted without being sent to the OLT if another user terminal address is registered already, along with a correspondence with the same multicast group identifier, in the multicast group management table.
