Optical cable junction boxes come in various sizes, typically ranging from compact wall-mounted units to larger dome enclosures, with dimensions such as 510×218 mm and 415×340×122.5 mm depending on the model.

Common Models and Dimensions

• Dome Mechanical Fiber Optic Junction Box (GJS-2001): Designed for 48 cores, this dome-type box measures 510 mm × 218 mm. It features one large port for straight-through cables and smaller ports for branch or drop cables, supporting cable diameters from 8 mm to 40 mm .
• Steel Fiber Optic Junction Box (01 Model): Suitable for outdoor wall or pole mounting, this box has dimensions of 415 mm × 340 mm × 122.5 mm. It includes a cooling fan for temperature regulation and multiple ports for connecting several fiber optic cables .
• SJ-ODB-M14 Optical Fiber Junction Box: A 48-core wall-mounted box made of iron, compliant with IP-55 standards. While exact external dimensions are not specified, it is designed for outdoor use with space for splitters and up to 48 SC adapters .
• Communication Optical Cable Cross Connecting Cabinet (PW-GJX-X110): This cabinet integrates heat sealing, roll storage, and fiber distribution. It can be mounted on the floor or aerially, but specific dimensions are not listed in the source .

Key Considerations

• Material: Boxes are commonly made from steel, iron, or high-strength PC plastic, providing durability and weather resistance.
• Capacity: Models vary in core capacity (24–48 cores) and can accommodate PLC splitters and SC adapters.
• Mounting: Options include wall-mounted, pole-mounted, or floor-mounted installations.
• Environmental Protection: Many boxes comply with IP-55 or higher, ensuring protection against water and dust. When selecting a junction box, it is important to match the dimensions and port sizes to the intended installation site and the number of fiber cores to be managed.
