With the remote transmission system, a total of eight pipeline sub-stations with distances of up to 100 km can be served and monitored. The remote transmission system is based on Fast Ethernet industrial switches for the development of fault-tolerant fibre optic rings. The ring topology means that any failures can be absorbed and a network reconfiguration done in less than 100 ms, thus ensuring constant availability of all network participants.
远程传输系统一共有距离可达100公里八个管道分站，可以用于服务和监管。远程传输系统是基于快速以太网工业交换机为发展容错光纤环而设计的。环状拓扑意味着可以处理任何故障，并在少于100ms内进行网络重新配置，从而确保所有上网的人不断网。
The setting up of the fibre optic network was carried out under high strain and partial desert conditions. Nevertheless, it was possible to equip the gas extraction sites with high-availability connections for the remote control and monitoring of extraction systems.
光纤网络是在高应变和局部沙漠条件下建立的。然而，它可在瓦斯抽放地配置具有高可用性连接的遥控系统和天然气抽取监测系统。
Outlook
In order to be able to implement applications like these in an even more flexible manner in the future, increasing use is being made of modular fibre optic connections in the form of SFP (Small Form-factor Pluggable) ports. Switches thus acquire a particular flexibility.
展望
为了能在将来更加灵活的使用此类应用，更多使用SFP（小型可插拔）端口模式的光纤连接。这样交换机需有更好的扩展性。

Some manufacturers offer both the Gigabit Ethernet standard (1000Base-X) as well as Fast Ethernet (100Base FX) for SFP slots. This means that, in addition to the media copper and fibre optic, different transmission speeds can be freely combined with one another at the same time. With the selection of pluggable SFP modules, care needs to be taken that these are also designed for the operating conditions of industrial networks.
一些厂商提供适合SFP插槽的千兆位以太网（100 Base FX）和快速以太网（100 Base FX）。这意味着，除了媒体铜和光纤，不同的数据传输速度可以在同一时间自由结合。除选择可插拔的SFP模块，还需注意这些也是为工业网络的操作条件特别设计。
In addition, a current topic is the implementation of Power-over-Ethernet pursuant to IEEE 802.3af. This standard offers the norm-compliant power supply of terminals such as VoIP telephones, wireless access points or IP cameras via the data connection. Firstly, the installation effort is considerably minimised, as no separate lines for the power supply need to be installed. Secondly, redundant design or protection via UPS is substantially simplified.
此外，当前流行的是根据IEEE 802.3af，来实现以太网供电。这个标准提供了规范兼容电源终端如VoIP电话，无线接入点或IP相机通过数据连接。首先，它很容易安装，因为供电设施不需安装单独线路。其次，多余设计或via UPS保护大大简化。
This example from practical experience shows that industrial Ethernet is in the process of taking over all other areas of application, beyond traditional industrial applications. Not for nothing is Ethernet the standard protocol for office, industrial and home networks.
从实际经验来看，这个例子说明工业以太网在其他领域应用的过程中，超越了传统工业应用。以太网标准不仅仅是办公室，工业和家庭网络的标准协议。
