Waterproof fiber optic junction box, also known as waterproof fiber optic junction box or waterproof fiber optic cable splice box, is a type of wiring equipment designed specifically for outdoor and humid environments. It not only effectively protects the fiber optic connection from moisture and dampness, but also has characteristics such as corrosion resistance and dust prevention, ensuring the stability and reliability of the fiber optic communication network.

Fiber optic junction box, commonly known as fiber optic junction box or fiber optic distribution box, is a key component in fiber optic communication systems, mainly used for fiber optic access, fusion splicing, distribution, wiring, and protection. Fiber optic junction boxes also have excellent mechanical strength, can withstand harsh environmental changes, and play a role in flame retardancy and waterproofing, protecting optical fibers from physical damage such as vibration, impact, tension, and distortion.
