FIB industry applications require extremely high network reliability Corning plc splitter

Industrial applications such as intelligent manufacturing and telemedicine rely on precise control and require the relevant transmission network to have extremely high reliability. According to the 3GPP TS 22.261 protocol, the network reliability needs to reach more than 99.999%. Usually, network reliability usually needs to be considered from three aspects: mean time between failures, mean time to recover from failure, and system availability. From the perspective of mean time between failures, passive distributed antenna systems are mainly composed of a large number of passive components and a small number of active devices. It consists of two parts. Under normal conditions, the failure probability of a single passive component with reliable connection is relatively low, but the indoor passive system consists of multiple passive nodes (modules) connected in series and parallel. When a passive node fails, the entire series system cannot be used. Work. The status of these passive nodes cannot be seen, and the faults cannot be monitored, and the mean time between failures of the system cannot be managed. From the point of view of the average fault recovery time, when a part of the traditional indoor network fails, engineers can only rely on the indoor passive system to analyze branch by branch and component by component, which is difficult to locate and rectify, and the fault recovery time is very long. Then, the availability of passive distributed antenna systems is relatively low. In general, the reliability of passive distributed antenna systems is low. Therefore, in order to meet the extremely high reliability requirements of 5G networks, while improving the robustness of the system, it is more important to realize the controllability of the network. corning plc splitter corning plc splitter corning plc splitter
Four generations of coexisting networks and the development of new services require the network to have efficient operation and maintenance and intelligent operation capabilities The passive distributed antenna system has a huge number of passive nodes, 100% of which cannot be monitored or managed. Routine inspection of a large number of passive network nodes requires a huge investment of human and material resources. Since the annual budget of the operator’s network maintenance department for indoor network maintenance is limited, only a few sites can be selected for routine testing, inspection, and rectification, which is difficult and time-consuming. This is a maintenance problem that has plagued the network maintenance department for a long time. In the 5G era, operators need to maintain four coexisting networks of 2/3/4/5G. The network architecture is more complex and maintenance is more difficult. In the 5G era, using network slicing to quickly open new services or enterprise services in certain areas is an important direction for operators to increase revenue. When activating services, it is necessary to evaluate network resource utilization in advance, predict the capacity requirements of new services and the satisfaction of service levels, so that service provisioning can be completed quickly. At present, the digitalization of indoor networks is not high enough to support refined evaluation and network resource prediction, and it is impossible to rapidly increase capacity in local areas. Instead, it is necessary to build an indoor system for enterprise business, which requires a long construction period and a large investment. For example, for the wireless medical office network requirements of a hospital, the operator cannot use the passive distributed antenna system already deployed by the operator, but must add a separate set of indoor wireless access network to activate services, which results in slow service provisioning and investment. low efficiency. At present, the passive distributed antenna system cannot meet the requirements in terms of head-end visibility and flexible expansion. How to build a digital network that can flexibly open new services, efficient operation and maintenance, and intelligent operation is an indoor 5G network construction.
