Cable transfer box is installed in outdoor connection device, it is the most fundamental requirements and can withstand drastic changes in climate and poor working conditions. It must have water
condensation, water-proof and dust-proof, anti-insect and rodent infestation, and strong resistance to impact damage characteristics. It must be able to withstand the outside environment bad.
Therefore, the outside box of waterproof, moisture-proof, dust-proof, anti-collision damage, anti-rodent pests, such as relatively high demand; the inside temperature and humidity control
requirements are very high. In accordance with international standards, these projects for the highest standards of IP66. However, to achieve the standard does not cover the box. At present, the
use of the cable transfer box box are: KRONE original box, Germany, the use of unsaturated polyester cabinet glass fiber reinforced materials (SMC), in the waterproof, moisture-proof,
anti-collision damage have better performance. KRONE internal reference imitation box is iron-based metal box (usually to meet IP65 standard). The metal box, due to water condensation in the
inferior aspects of the performance of large-scale use will not be doomed, and will gradually be eliminated.
Cable transfer box is a fiber optic backbone layer, wiring layer to provide fiber optic cable into a client
