Traditional connecting devices provide users with several years of service assurance in a typical office environment. However, if the same copper cable or optical fiber connector is exposed to extreme conditions, its performance and reliability will decline, and the end user must pay high maintenance costs to troubleshoot and replace accessories. A new connector, which is specially designed to build a strong Ethernet connection in harsh environments, is stronger, stronger and more resistant than the previous connector. This new interface is generally considered as "industrial connector", and its application is not limited to manufacturing industry. This connector is designed to withstand the most severe industrial environment.
