![]() ![]() The role of optical fiber splice closure in FTTx According to the sealing method, there are heat shrinkable sealing type and mechanical sealing type. According to the connection method of optical fiber cable, it is divided into two types, straight-through connection and split-fiber connection.Ĥ. According to the laying method of optical fiber cable, there are overhead, pipeline (tunnel) and direct buried types.ģ. According to the shape and structure, it can be divided into two types, vertical optical fiber splice closure and horizontal optical fiber splice closure.Ģ. Optical fiber splice closure classificationġ. At the cable entry point, use a blowtorch to heat slowly from the middle to the two ends, so that the entire heat shrinkable tube can be completely shrunk. Clean the polished area with detergent, paste it with aluminum foil, and then put the heat shrinkable tube on the optical fiber splice closure. Use abrasive cloth to polish the junction of the optical fiber splice closure and the optical fiber cable at the cable entry point of the base. Seal the optical fiber cable and the optical fiber splice closure. For the protection of optical fiber connectors, place the heat-shrinked protective sleeve on the fiber core fixing clip in the receiving tray, and the silica gel fixing method can also be used.ĥ. The storage tray can be multi-layered and has a larger capacity, and the storage tray can be adjusted according to the number of cores connected by the optical fiber cable.Ĥ. The length of the remaining optical fibers should not be less than 1 meter, and the labyrinth of the remaining optical fibers should not be less than 35mm. The optical fiber placement device can store the optical fiber connectors and the remaining optical fibers in order. The third is the sealing and fixing of the fiber optic cable and the inlet and outlet cables of the splice box with a heat-shrinkable sheath.ģ. The first is the internal fixation of the fiber optic cable strengthening core. The second is the clamping and fixing of the optical fiber cable and the support frame. Optical fiber cable fixing device, used for fixing the optical fiber cable and the base and fixing the reinforcing element of the optical fiber cable. The support frame is the main body of the internal components.Ģ. Internal structure of optical fiber splice closureġ. It mainly completes the connection between distribution optical fiber cables and household optical fiber cables outdoors, and can install box-type or simple optical splitters according to FTTX access needs.Įxample: 24 Cores Splice Tray 2 IN 2 OUT Mechenical Splicing ![]() Widely used in communications, network systems, CATV cable television, optical cable network systems and so on.It is a common equipment for protective connection and optical fiber distribution between two or more optical cables. The structure is mature, the sealing is reliable, and the construction is convenient. The optical fiber splice closure body is made of imported reinforced plastic, which has high strength and corrosion resistance. It is mainly used for straight-through and branch connections of overhead, pipeline, direct burial and other laying methods of optical cables of various structures. It belongs to the mechanical pressure sealing joint system and is a splicing protection device that provides continuity of optical, sealing and mechanical strength between adjacent optical cables. Optical fiber splice closure, also known as optical cable splice box and fiber joint box. It must be used in the construction of fiber optic network and is one of the very important equipment. The quality of the optical fiber splice closure directly affects the quality and service life of fiber optic network. Optical fiber splice closure is a connection part that connects two or more fiber optical cables together and has protective components. ![]()
