Why do you say that? Fiber optic cable splice box is a necessary equipment in the construction of fiber optic cable lines. It connects two or more optical cables together and provides complete protection for the fiber optic connection part. Once the box is damaged or leaks due to various weather conditions, the internal optical cable must also be inevitably damaged. For example, once there is a water leak, it is highly likely to cause internal freezing in low temperature weather, which will directly affect the use of fiber optic cables.
From the application situation on the market, if there is a malfunction in the communication line, it is mostly due to the poor quality of the fiber optic cable joint box, such as inability to resist adverse weather, box thermal expansion and contraction, poor sealing, and other reasons.
So, that's why the fiber optic cable splice box needs to be of very high quality. Note that "high quality" here does not mean hardness, but rather means it needs to have multiple durable qualities, such as being able to withstand extremely high or low temperature environments, having an impact resistance of IK10+, meeting the protection level of IP68 (the highest level of connector waterproof level standard), and also requiring strong sealing and insulation, Has good resistance to alkali salt corrosion and aging, as well as strong resistance to outdoor environments. At present, most of the boxes on the market are made of engineering plastic materials, which require performance to meet a service life of no less than 20 years.
