It adopts a loose tube structure, and the internal optical fibers are generally arranged in a loose packing manner, which is convenient for maintenance and repair. In most cases, non-metallic materials, such as polyethylene (PE), are used. This design helps to reduce weight and improve corrosion resistance.
Troubleshooting assistance and system compatibility solutions, available whenever you need them.
