本项目的范围是修改IEEE标准802.3，为支持下行方向25Gb/s或50Gb/s MAC数据速率，上行方向10Gb/s、25Gb/s或50Gb/s MAC数据速率的点对多点无源光网络添加物理层规范和管理参数，距离和分裂比与IEEE标准802.3中定义的一致。它还扩展了以太网无源光网络（EPON）协议的操作，如多点控制协议（MPCP）和操作管理（OAM）。

The scope of this project is to amend IEEE Std 802.3 to add physical layer specifications and management parameters for point-to-multipoint passive optical networks supporting MAC data rates of 25 Gb/s or 50 Gb/s in the downstream direction and 10 Gb/s, 25 Gb/s, or 50 Gb/s in the upstream direction, with distance and split ratios consistent with those defined in IEEE Std 802.3. It also extends the operation of Ethernet Passive Optical Networks (EPON) protocols, such as MultiPoint Control Protocol (MPCP) and Operation Administration and Management (OAM).
