As a key component in the optical cable line, the junction box has many significant technical features.
First, in terms of structural design, the box body is usually injection molded by high-quality materials, such as high-engineering plastics, with good resistance to alkali and salt corrosion and aging, smooth and beautiful surface, and firm mechanical structure. Box bodies made of aluminum alloy have strong corrosion resistance and aging resistance, can withstand drastic climate changes and harsh working environments, and provide reliable protection for optical cables.
In terms of function, the junction box has excellent protection performance. It has good sealing and moisture-proof performance, and is equipped with a sealing ring inside, which can be opened repeatedly without air leakage, without special tools, and is easy to operate. At the same time, it can effectively avoid the loss of light power transmission and ensure the stability of optical cable connection.
The junction box also does a good job in fixing and protecting the optical cable. It can provide a fixed and reinforced core grounding protection device for the optical cable, and has a unique reinforced core fixing component and rubber strip sealing technology. The internal space is reasonably designed, leaving enough fiber winding curvature radius and space to ensure that the fiber curvature radius meets the standard and reduce light attenuation.
In terms of tolerance, the junction box can withstand large axial tensile forces, has a wide operating temperature range, and can work normally in an environment of -40℃~+60℃.
In addition, in terms of technical parameters, the junction box has high insulation resistance, strong pressure resistance, and clear and high standards for fiber winding curvature radius and stretching. These technical features jointly ensure that the junction box can operate long-term, stably and efficiently in the optical fiber communication system.
