The optical cable cross-connect box is a connection device installed outdoors. The most fundamental requirement for it is to be able to withstand drastic climate changes and harsh working environments. It must be resistant to condensation, water and dust, insect and rodent damage, and strong impact damage resistance. It must be able to withstand relatively harsh external environments. Therefore, the outside of the box has relatively high requirements for waterproofing, moisture-proofing, dust-proofing, impact damage, and insect and rodent damage; the inside has very high requirements for temperature and humidity control. According to international standards, the highest standard for these projects is IP66. However, there are not many box shells that can meet this standard. At present, the main optical cable cross-connect box boxes used in China are: original German KRONE boxes, which are made of unsaturated polyester glass fiber reinforced material (SMC), and have good performance in waterproofing, moisture-proofing, and impact damage. Domestic imitations of KRONE boxes are mainly metal boxes made of iron (generally meeting IP65 standards). Due to their poor performance in waterproofing and condensation, metal boxes are destined not to be used in large quantities and will gradually be eliminated. Due to material performance problems, some domestic imitations have great differences in waterproofing and impact resistance compared with the KRONE imported from Germany. In addition, due to the poor anti-aging performance of the sealing strip, the performance in waterproofing and dustproofing is also average. Of course, when the external environment of the optical cable junction box is relatively good, it is acceptable to reduce performance requirements and reduce investment.
