Features

The transfer box has the functions of wiring, fusion splicing, fiber storage, and fiber adjustment. It has strong resistance to the field environment, and can withstand severe climate changes and harsh working environments. The box has good sealing performance and the protection level reaches IP65 requirements. .
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.
Modular design, reasonable layout, multiple functions and high density.
It adopts a six-position adapter card strip structure; FC or SC adapters can be used according to user needs.
It has good sealing performance, strong resistance to the field environment, and can withstand severe climate changes and harsh working environments. The cabinet has good sealing performance and the protection level reaches IP65 requirements.
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.
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.
The radius of curvature of the optical fiber is ≥30mm (internally controlled 40mm).
The rack has a good grounding system.
The plastic parts inside the machine are made of flame-retardant materials.
