The offshore oil and gas exploration fixed facilities have long been working in a harsh and complex marine environment, and are affected by waves, corrosion, erosion, fatigue and other unfavorable factors. A stable and reliable system is needed to monitor its operating status in real time and continuously, and the network system is monitored. The basic communication facilities of the system need to provide stable data transmission services in the same environment. The network equipment should have the ability to work stably for a long time in a wide temperature, corrosion and vibration environment, and provide high performance for SCADA, video, voice and other multi-service systems. Performance communication support.
