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.
