What are the advantages and design features of fiber optic splice closures?

The capacity of the splice tray of the optical cable splice box is 12 cores per tray in a single-core bundle, and 24 cores per tray in a double-core bundle.

The functional characteristics of the optical cable splice box are: it can protect the optical fiber and the optical fiber joint from vibration, punching, bending, etc. and avoid moisture. The difference between the splice box and the terminal box is: the splice box is fully sealed and can be waterproof, but it cannot fix the pigtail; the terminal box is not waterproof, but the internal structure can not only fix the optical cable, but also fix the pigtail.

The optical cable splice box also has good sealing performance. The transmission attenuation of the optical fiber is closely related to the waterproof function. Therefore, the splice box must have excellent air-tight and waterproof functions. The splice box must have a certain mechanical strength to ensure the joint. When the pressure applied at the box reaches 70% of its strength, the function of the fiber in between is not affected. At present, the shell of most joint boxes is made of plastic products, in addition to corrosion resistance, aging resistance and insulation functions of the material. The splice box should be easy to disassemble and the material can be reused. The splice box should be as simple as possible to reduce the labor intensity during connection and shorten the operation time.

The splice box should be composed of four parts: shell, internal components, sealing elements, and maintenance parts for fiber optic connectors. The effect of the casing should be specifically mentioned here: when required, a grounding lead-out device is installed on the casing to lead out the metal components in the splice box and the optical cable to the ground. Alternatively, a valve can be installed on the casing to inflate and measure the air pressure during sealing inspection in the joint box. Where necessary, the splice box should also be protected against damage (for example, termite resistance). Measure the transmission characteristics (program, end type) of the optical cable, check the insulation resistance joint of the sheath to the ground, and then mark and record the optical fiber in sequence. It is carried out in a vehicle or a joint tent, dust and harmful gas (Freon) pollution, and the ambient temperature is ≧ 0° to ensure the flexibility of the optical fiber and the normal operation of the welding equipment. Length ≧60cm, connect as much as possible, otherwise measure the connector loss after the optical fiber connection should be protected from moisture and safety. For qualified repackaged maintenance pipes, the joint pit of the direct buried optical cable should be located on the right side of the route A→B, otherwise the left side should be marked on the route construction drawing. The shell of the joint box is made of electrostatic spray, which is beautiful in appearance and easy to use. The splice box is equipped with optical cable fixing equipment, splicing trays, and wire loops.
