A flexible Optical Service Unit (OSU) path layer is specified by this standard for optical networks, providing services ranging from 2 Mb/s to 100 Gb/s. The main features of the OSU path layer are being offered in the form of massive OSU connections that carry packet and Constant Bit Rate (CBR) services with guaranteed performance, enabling the flexible hitless bandwidth adjustment (e.g. n × 10 Mb/s) for each OSU connection, along with capabilities such as high bandwidth efficiency, large capacity, and low latency. The OSU path layer can be carried on different server layers, for instance, OTN, PON, among others. The standard supports high-quality leased line services and video services, with guaranteed performance, that are utilized in telecom operator’s optical networks and other industry transport networks.
