The box body is made of high-quality stainless steel plate, which not only has good corrosion resistance and aging resistance, but also has a beautiful appearance.
The box body can be opened from the front or back. There is ample space for cloth fiber and fiber storage, enough winding reels and hooks for user operation.
Modular design, reasonable layout, multiple functions and high density.
It adopts anti-theft door lock shape, which is safe and reliable, and has good anti-vandalism function. The box body has a flexible fiber optic cable structure and a flexible internal connection structure.
Using flying saucer type direct melting plate, small volume, large direct melting capacity.
It adopts a six-position adapter card strip structure; FC or SC adapters can be used according to user needs.
The cabinet is compact, light and easy to install.
FC or SC adapters can be used. The adapter has a 40° bevel to avoid direct arc light to human eyes.
According to the needs of users, the fiber optic cable reinforcement core can also be in the form of a fixed cover for the fiber optic cable, which is suitable for ordinary and ribbon fiber optic cables.
Grounding method: The box body has two layers of ground, the first layer is a protective ground, and the fiber optic cable reinforcement core is connected to the protective ground. The other layer is the rack ground. The grounds of the two layers are not connected to each other, and they lead to the ground of the machine room through their respective ground wires.
There is a special fiber optic cable through welding area in the box, and the two ends of the fiber optic cable are connected in the through welding area
