Have you noticed a black box on the roadside cable? Do you know what it is? Why install a black box?In fact, its name is: Cable Joint Box, which is mainly used for the connection, branching and switching of cables or wires. It can connect multiple cables together to form a continuous optical signal transmission channel, while protecting the optical cable from damage from the external environment.
Structure of Cable Joint Box:
The outer shell of the cable joint box is usually made of engineering plastics or metal materials (such as aluminum alloy, stainless steel, etc.), which are corrosion-resistant and wear-resistant. The cable joint box can generally be opened to facilitate internal operation and maintenance. Common structural forms include cap type, horizontal type, vertical type, etc. The interior of the cable joint box is divided into optical fiber splicing tray, optical fiber receiving area, sealing element and grounding device. The optical fiber splicing tray is provided with optical fiber fixing groove, fusion splicing tray, etc., Cable joint box are used to fix and retain optical fiber. The optical fiber receiving area can retain and store excess optical fiber, usually with wiring grooves and fixing devices to avoid signal loss caused by optical fiber clutter. Sealing elements include sealing strips, sealants, etc., which are used to seal the various interfaces of the joint box to prevent water, dust, etc. from entering the box. The grounding device is used to ground the splice box to prevent damage to the optical fiber network caused by accidents such as lightning strikes.
Features of the Optical Cable Junction Box:
Optical cable junction box is highly flexible and can adapt to different application scenarios and optical cable types. Whether it is a single-core cable or a multi-core cable, Optical cable junction box can be quickly connected, reducing the difficulty and time of construction. Cable joint box can maintain its inherent thermal expansion and contraction properties according to the climate environment, and can still maintain good sealing in an environment with a large temperature difference. It is suitable for use in deserts, mountainous areas and other areas to ensure stable operation of the equipment. Optical cable junction box is made of environmentally friendly materials, non-toxic and harmless, recyclable and reusable, in line with the requirements of sustainable development, and reduces pollution to the environment. Optical cable junction box is easy to install and has sufficient operating space for later maintenance and overhaul.
