Improve the durability of fiber optic connectors

The horizontal fiber optic splice connector is an indispensable part of the optical fiber communication line. Its main function is to realize the connection of the optical fiber cable. At the same time, in order to ensure the grounding function of the optical fiber connector, the internal grounding device and the grounding portion of the optical cable should be electrically connected, and the optical fiber. The metal parts of the connector and the grounding device should be electrically connected. In order to avoid adverse effects on the cable joint closures, it is important that they are insulated from one another and that the pressure resistance of the fiber connector joints is improved.

In order to prevent lightning strikes or other factors, the fiber splice connector must meet the standard application of 15 VDC for 1 minute without breakdown and no arcing. Therefore, high requirements are placed on the fixing and grounding of the fiber splice connector and the design of the insulating material used. Reasonable and sturdy insulation is the fundamental guarantee for high voltage DC breakdown. There are many insulating materials on the market today, but we need to make appropriate choices based on the standard requirements, combined with the dielectric properties and plasticity of the material itself.

Therefore, the structure and material of the insulation as well as the surface condition also have a great influence on the withstand voltage strength performance of the fiber splice case. If you want to improve the withstand voltage performance of fiber splice connectors, you must use a better insulating material, such as Teflon, to increase the surface finish and reduce the curvature between the insulators and between the poles. Insulating gaskets commonly used in fiber optic splice closures typically consist of two upper and lower spacers, the upper washer being a recessed washer and the lower washer being a male washer.
