NE820 是一款适用于恶劣环境的工业开关。由于我们的多速率 SFP 解决方案，该交换机可用于 100 Mbit 或千兆网络。我们独特的 FRNT（网络拓扑快速恢复）技术是市场上最快的协议，可在任何链路或硬件故障的情况下重新配置网络。因此，NE820 还用于隧道、交通信号控制和铁路系统等安全关键型应用。

在恶劣环境和电气干扰严重的地方进行安装需要使用可靠的介质。NE820提供了许多使用光纤收发器的解决方案。多模或单模收发器可用于构建点对点或冗余环形网络，每个开关之间的范围可达 120 km。我们的 BIDI 收发器在单根光纤上发送和接收数据，可用于光纤芯数有限的应用。

在交换机中实现实时属性，以实现实时关键应用的确定性。NE820支持QoS（Quality of Service），具有四个优先级队列和严格的优先级调度以及HoL（Head of Line Blocking Prevention）。所有这些都是为了确保数据网络是确定性的。

The NE820 is an industrial switch for harsh environments. Thanks to our multi-rate SFP solution, the switch can be used on 100 Mbit or Gigabit networks. Our unique FRNT (Network Topology Fast Recovery) technology is the fastest protocol on the market to reconfigure the network in the event of any link or hardware failure. As a result, the NE820 is also used in safety-critical applications such as tunnels, traffic signal control and railway systems.

Installation in harsh environments and places with high electrical interference requires the use of reliable media. The NE820 offers a number of solutions using fiber optic transceivers. Multimode or single-mode transceivers can be used to build point-to-point or redundant ring networks with a range of up to 120 km between each switch. Our BIDI transceivers send and receive data on a single fiber for applications where the fiber core number is limited.

Implement real-time properties in switches to achieve certainty for real-time critical applications. The NE820 supports Quality of Service (QoS), four priority queues, strict priority scheduling, and Head of Line Blocking Prevention (HoL). All of this is to ensure that the data network is deterministic.
