As we all know, on October 31, 2019, the three major operators announced 5G business package, and officially launched 5G business package on November 1. It marks that China has officially entered the 5G commercial era.

The fifth generation mobile communication technology (English: 5th generation mobile networks or 5th generation wireless systems, 5th generation, referred to as 5G or 5G Technology) is the latest generation of cellular mobile communication technology, which is also the extension of 4G (LTE-A, WiMAX), 3G (UMTS, LTE) and 2G (GSM) systems. 5G's performance objectives are high data rate, reduced latency, energy saving, cost reduction, increased system capacity and large-scale device connectivity. The first phase of the 5G specification in release-15 was to accommodate early commercial deployments. The second phase of release-16 will be completed in April 2020 and submitted to the International Telecommunication Union (ITU) as a candidate for imt-2020 technology. ITU imt-2020 requires a speed of up to 20 Gbit / s, which can realize wide channel bandwidth and large capacity MIMO.

With a long-term investment in the research and development of optical transmission products, the new generation OTN-2800 series of large bandwidth optical intelligent transmission platform emerged after the previous generation of DWDM XYT-1600 series transmission products.

OTN-2800 series products carry NMS-3000 network element management software. Based on the B/S architecture, the software can create the topology of subnets, network elements and fiber cables, configure the network element data, check or modify the board parameters, and then manage the subnets, network elements or cables through NMS-3000.

The network element management software of SharetopNMS-3000 has four functions: performance management, fault management, configuration management and security management. It also adopts graphical user interface, which is flexible in operation and perfect in function. Through NMS-3000 network management system, network service quality can be improved, maintenance cost can be reduced, and reasonable use of network resources can be guaranteed.
