[Abstract]:5G is moving towards higher rates, lower latency, lower power consumption, Fronthaul optical network has become one of the indispensable means to improve its comprehensive capability. This paper expounds the "three one" viewpoint of the future development trend of 5G pretransmission optical network (a key problem, an important feature, A development goal is to explore the multi-dimensional multiplexing technology of optical network resources for 5G large bandwidth and low delay transmission requirements. The high speed and low delay transmission of massive data is the key problem in 5G pretransmission optical network. The number of antennas and the deployment of virtualization technology are increasing rapidly. As a result, the topology of 5G forward optical network is no longer a fixed point-to-point connection form. Constructing a flexible and reconfigurable forward optical network is an important feature of implementing 5G resource efficient configuration. It is also another development goal of 5G pretransmission optical network in the future to build a deep intelligent control management system based on the combination of artificial intelligence and machine learning and the high quality data transmission under the diversified business access such as the Internet of things.
