Overhead optical cable splicing package
optical cable Connector The box is the connection part that connects two or more optical cables together and has protective parts. It must be used in the construction of optical cable lines and is one of the very important equipment. The quality of the optical cable junction box directly affects the quality of optical cable lines and the service life of optical cable lines. The optical cable splice box is a popular name, and its scientific name is optical cable splice box, also known as optical cable splice package, optical cable splice package and gun barrel. It belongs to mechanical pressure sealing joint system, and is a connection protection device that provides optical, sealing and mechanical strength continuity between adjacent optical cables. It is mainly applicable to overhead The Conduit , direct burial, etc Straight through And branch connections. The box body is made of imported reinforced plastic, with high strength and corrosion resistance. The terminal box is suitable for the connection in the terminal machine room of structural optical cables, with mature structure, reliable sealing and convenient construction. It is widely used in communication and network systems, CA TV cable TV, optical cable network system, etc. The right side is the two in and two out connector box;
It is used for protective connection and optical fiber distribution between two or more optical cables. It is one of the commonly used equipment at user access points. It mainly completes the outdoor connection between distribution optical cables and incoming line optical cables, and can be installed with box or simple optical splitters according to the needs of FTTX access [1]· The box body of the product is of high quality engineering plastic 。· The product adopts twice cable pressing technology to ensure that the optical fiber in the box has no additional attenuation· The product has multiple reuse and capacity expansion functions· Tensile tightness: 2000N axial tension, no air leakage· Voltage withstand strength: 15KV (DC)· Tension seal: after the product is inflated, it can withstand 2000N axial tension without air leakage· Impact sealing: after the product is inflated, it can withstand impact energy of 16N * m (* m) for three times, and the product is free of cracks and air leakage· Other performance requirements meet the requirements of YD/T814.1-2004 standard. According to the shape and structure, it can be divided into cap type optical cable splice box and horizontal optical cable splice box;
According to the laying method of optical cable, there are overhead, pipeline (tunnel), direct burial and other types; According to the optical cable connection mode, it can be divided into straight connection and branch connection; According to the sealing method, there are heat shrinkable seal type and mechanical seal type. According to YD/T814.1-2004, the model should reflect the professional code, main name code, use site code, optical cable connection mode code, sealing mode code and specification of the product. For example, the marking table of the three branch optical cable connector box of 24 core overhead optical cable sealed by mechanical sealing is GJSxx-JF3K24. It has the performance of restoring the integrity of the optical cable sheath and the mechanical continuity of the optical cable stiffener. Provide the function of electrical connection, grounding or disconnection of the metal components in the optical cable. It has the performance of protecting the optical fiber connector from environmental impact. Provide the placement of optical fiber connectors and the function of remaining optical fiber storage. When necessary, the optical cable joint box shall also be termite proof. The optical fiber connector shall be protected from moisture after being protected by the connector box.
