This standard specifies a communication layer denoted as Flexible Optical Service Unit (OSUFlex). OSUFlex provides point-to-multipoint service channels in optical transport networks. This layer features support for a large number of OSUFlex connections, enabling direct transmission of power industry services such as Internet of Things (IoT) data, surveillance camera video streams and industrial bus data across optical transport networks. For each point-to-multipoint connection, OSUFlex supports flexible bandwidth allocation in the form of n × 2 Mb/s as well as hitless bandwidth adjustment. This standard enables highly efficient direct service mapping onto OSUFlex, and delivers physically isolated service channels to meet the application requirements of power systems.
