Details Of The Internal Configuration Of The Vertical Fiber Opt

  •  

    The vertical optical cable connection box, also called the Fiber Optic Splice Closure and the barrel, is the place where the end of the optical cable is connected, and then accesses the optical switch through the optical fiber jumper. Prevents the aging of materials caused by heat, cold, light, oxygen and microorganisms in nature, and has excellent mechanical strength. The sturdy cable joint box casing and main structural components can withstand the worst environmental changes, and at the same time, it is flame retardant and waterproof. The function is to protect the vibration, impact, cable tension, distortion and the like.

    Internal structure:

    1. Support frame: It is the main body of internal components.

    2. Optical cable fixing device: used for fixing the optical cable and the base and fixing the optical cable reinforcing component. The first is the fixing of the cable reinforcing core inside; the second is the fixing of the cable and the support frame; the third is that the cable and the connector box are sealed and fixed by the heat shrinkable jacket.

    3. Fiber-optic placement device: The fiber-optic connector and the remaining fiber can be stored in sequence, the length of the remaining fiber should be no less than 1 meter, and the remaining fiber-optic disk should have a mean diameter of not less than 35 mm. The storage tray can be four layers, the capacity is large, and the storage tray can be adjusted according to the number of cores connected by the optical cable.

    4. Optical fiber joint protection: The heat-shrinkable protective sleeve can also be placed on the core fixing clip in the receiving tray.

    5. Cable and connector box sealing: sand the interface between the connector box and the optical cable with the abrasive cloth on the cable and the base cable. Wipe the sanding area with the cleaning agent, attach the aluminum foil, and place the heat shrinkable tube in the joint box. At the entrance of the cable, the burner is slowly heated according to the middle and rear ends, so that the entire heat-shrinkable tube can be completely contracted.

    use:

    1. It is suitable for straight-through and branch connection of overhead, pipeline, direct burial and other laying methods of various structural optical cables.

    2. Connection in the terminal room of the structural cable.

    3. The fiber optic cable connection box is generally suitable for indoor or non-open outdoor use, and is not suitable for outdoor use. If it is to be used, protective measures should be taken. Working temperature: indoor type: -5 ° C ~ +40 ° C; outdoor type: -20 ° C - + 60 ° C.

    classification:

    1. According to the shape structure classification, it can be divided into hat type and horizontal type.

    2. According to the classification of the outer casing material, it can be divided into a plastic outer casing and a metal outer casing.

    3. According to the cable connection method, it is divided into straight-through connection and divergent connection.

    4. Classified according to the sealing method, divided into heat shrinkable seal type and mechanical seal type.

    5. There are overhead, pipeline (tunnel) and direct burial types according to the way the cable is laid.

    6. According to whether the adapter classification can be assembled, it can be divided into an adaptable adapter type and a non-assemblable adapter type.

    Features and features:

    1. The optical cable connection box can be used for welding part of the main optical cable and the divergent optical cable at the same time, and the partial trunk optical cable is welded to the pigtail or the tail cable, and is connected to the optical switching device through the fiber jumper. The welding unit, the wiring unit, the part of the material of the network box casing, the optical cable of the cable connection box to the network box, and the entire operation process can be omitted.

    2. The fiber fusion splicing unit increases or decreases the fiber accommodating disk to save time and time. The flip angle of the fiber condensing disk reaches 90°C or above, which is convenient for future expansion and maintenance.

    3. Optical fiber distribution unit, can install FC, SC, ST, LC adapter fixed module, installation is very convenient, can be configured according to user needs, each module size and mounting holes are the same.

    4. Innovative structural design, convenient and reliable installation, the whole set of plastic parts adopts scientifically formulated high-strength PC engineering plastics, and the injection molding can be used for a long time in the natural environment of -40 °C ~ +65 °C.

    5. Patented product - the elastomeric sealing member can be repeatedly opened and reused repeatedly to maintain good sealing performance.

    6. Multi-function optical cable connection box, which can be installed by hanging wall or pole. Realizing FTTH access for fiber network construction reduces costs and improves communication quality.
