Pre-connectorized patchcord (GJXH) is designed for harsh industrial environments and FTTx/FTTH applications. It has corrosion-resistant, waterproof, and dustproof protection and easy FTTx installation and termination using existing hardware and installation methods for drops to homes and businesses. This article provides some knowledge about pre-connectorized patchcord (GJXH). What is a Pre-Connectorized Patchcord (GJXH)? Pre-connectorized patchcord (GJXH) is a small waterproof SC/APC connector. Built-in SC connector core, its plastic enclosure is resistant to high and low temperatures, acid and alkali corrosion, and anti-UV. A waterproof rubber gasket enables it to deliver IP68 waterproof performance. It applies to 2×3/ 3.0/5.0mm FTTH drop and round cables. Cable Construction FTTH drop cable(GJXH) uses a butterfly flat structure, and the optical fiber unit is positioned in the center. Two parallel fiber-reinforced plastic (FRP) or steel wire strength members are placed at the tw
