[Abstract] For 5G mobile services, the fronthaul, midhaul and backhaul services can be achieved by optical transport network (OTN). As the foundation of the bearing technology, OTN can provide large bandwidth, low latency, flexible fragment, high reliability, and open collaboration capabilities, and is suitable for the fronthaul and backhaul networking in 5G era. OTN can also support the development of other services, such as fixed network, so as to meet the needs of the continuous evolution of future networks.
