Purpose This layer serves to visualize and track the development and deployment of California's open-access middle-mile broadband network. It details the planned and constructed fiber optic infrastructure designed to extend high-speed internet connectivity to unserved and underserved areas across the state, supporting goals of equitable access for all Californians. Details This GIS layer contains polyline features representing the physical infrastructure of the statewide middle-mile broadband network. The data is derived from Senate Bill 156, which allocated $3.25 billion for the construction of this network. Technologies represented may include Fiber Network and Caltrans Network. The data's accuracy and completeness are subject to ongoing development and construction phases. The primary source of the data is the California Department of Technology (CDT) in collaboration with Caltrans and other stakeholders involved in the MMBI project. The geometry type is esriGeometryPolyline. Attributes Version by month and year. Process Updated last monday of each month History The data originates from Senate Bill 156, signed in July 2021, to establish an open-access middle-mile network. Initial data reflects the network's presence and updates based on its stages of Planning, Design, Construction, and Operation and Maintenance. Data Steward - MMBI GIS and Data

用途：本图层用于可视化并追踪加利福尼亚州开放访问式中程宽带网络（middle-mile broadband network）的建设与部署进程。该图层详细记录了为向全州未覆盖及服务不足地区提供高速互联网连接而规划、已建成的光纤基础设施，助力实现所有加州居民公平获取互联网接入的目标。
