This standard builds upon the IEEE Std 802.3ca™-2020 Physical Layer Specifications and Management Parameters for 25 Gb/s and 50 Gb/s Passive Optical Networks standard and creates a system-level and a network-level specifications, thus allowing full "plug-and-play" interoperability of the transport, service, and control planes in a multi-vendor environment. This standard has the scope and the purpose similar to IEEE Std 1904.1™-2017 Standard for Service Interoperability in Ethernet Passive Optical Networks (SIEPON), but it extends to 25G-EPON and 50G-EPON architectures. In addition to increased data rates, it specifies system-level functions necessary to support multi-channel operation with channel bonding, new bandwidth allocation methods, and new logical link provisioning.
This standard describes the system-level requirements needed to provide service-level, multi-vendor interoperability of Ethernet Passive Optical Network (EPON) equipment. The specifications complement the existing IEEE 802.3™ and IEEE 802.1Q™ standards, which enable the interoperability at the Physical Layer and Data Link Layer. Specifically included in this specification are:
