The cable transfer box is a transfer equipment that provides the optical cable for the main layer optical fiber cable and the wire layer optical fiber cable and jumps. After the fiber optic cable is introduced into the cable transfer box, after the fiber cable is fixed, terminated, and equipped with fiber, the optical fiber cable of the trunk layer and the optical fiber of the wiring layer are connected by using a fiber jumper.
Performance <br> <br> cable transfer box is connected to equipment installed outdoors, its most fundamental requirement is the ability to withstand drastic changes in climate and poor working conditions. It must have the characteristics of waterproof condensation, waterproof and dustproof, pest and rodent damage, and strong resistance to impact damage. It must be able to withstand the harsh external environment. Therefore, the outside of the box is required to be relatively waterproof, moisture-proof, dust-proof, impact-proof, pest-resistant, and the like; the inner side has a very high temperature and humidity control requirement. According to international standards, the highest standard for these projects is IP66. However, there are not many case shells that can meet this standard. At present, the domestic optical fiber cable transfer cabinets mainly include: original German KRONE cabinets. The cabinet is made of unsaturated polyester glass fiber reinforced material (SMC), which has good performance in waterproof, moisture-proof and anti-collision damage. Domestic reference to the KRONE box is an iron-based metal box (usually IP65 standard). For the metal box, because of its poor performance in the condensation of water vapor, destined to not be used in large quantities, and gradually eliminated. Some of the domestic imitations due to material performance problems caused the box in the water vapor condensation and impact resistance of the two properties with the introduction of Germany's KRONE there is a big difference, in addition to the anti-aging properties of the sealing strip is poor, in the waterproof, dustproof two The performance of the item is also general. Of course, when the external environment of the installation position of the cable transfer box is relatively good, it is acceptable to reduce the performance requirements and reduce the investment.
Structure <br> <br> by a general cable transfer boxes: box, integrated splice tray, cable fixing plate, hanging fiber column composed of several parts. Fiber optic cable transfer boxes are mainly 48 core, 96 core, 144 core, 288 core, 576 core several. The common box material is the SMC box. (SMC is an acronym for Sheetmolding compound, which is a sheet molding compound. The main raw material consists of SMC special yarn, unsaturated resin, low shrinkage additive, filler and various additives. It first appeared in Europe in the early 1960s. Around the United States and Japan, this technology was developed around 1965. In the late 1980s, China introduced advanced SMC production lines and production processes abroad, and SMC has superior electrical properties, corrosion resistance, light weight, and easy engineering design. Due to its flexibility and other advantages, its mechanical properties are comparable to those of some metal materials, making it widely used in transportation vehicles, construction, and electronics/electrical industries.)
The main features (1) fully enclosed chassis, dust, waterproof, beautiful appearance.
(2) Straight fiber specifications, to meet the optical fiber bending radius greater than 40mm.
(3) It can meet the needs of the use of both ribbon and non-ribbon optical cables.
(4) It has safe and reliable optical fiber storage and protection functions.
(5) The identification is clear, and there is a clear identification of the connection and distribution of each core fiber.
(6) The fully modularized transfer box can be assembled flexibly according to customer requirements, facilitating construction and maintenance.
(7) Optical cable fixation, stripping, and grounding can be easily performed.
