Description

Technical Field

[0001] This utility model relates to the field of protection device technology, specifically to an anti-EMP pole-mounted fiber optic communication line protection device. Background Technology

[0002] Electromagnetic pulse (EMP) resistant poles are facilities designed to defend against electromagnetic pulse attacks. An electromagnetic pulse (EMP) is a high-energy electromagnetic radiation that can originate from natural sources (such as solar storms) or man-made devices (such as EMP generated by a nuclear explosion). When an EMP reaches a certain intensity, it can damage electronic equipment and even cause large-scale power grid failures and communication outages.

[0003] Currently, in the actual construction and use of existing electromagnetic pulse (EMP) protection poles, it is necessary to lay pipeline communication lines. When laying the lines, it is often necessary to connect two fiber optic communication cables. The commonly used connection method is to use a plug-in connector. However, after connecting two fiber optic communication cables, the plug-in connector is directly exposed to the outside air. Under the influence of the external environment, dust and moisture in the air can easily penetrate into the interior of the connector, causing a short circuit at the connection point of the communication cables.
