As you known, greentelftth is a professional Dome Fiber Closure manufacturer, we offer high-quality closure for you, the material of greentel DOME Fiber Closure should meet the condition.

According to statistics, most of the failures of the optical cable lines are caused by poor quality of fiber optic splice closure. The factors influencing the quality of the fiber optic splice closures include the sealing of the housing and the end of the optical cable, the strength of the body, and the resistance to environmental conditions, among which the sealing performance of the fiber optic splice closure is a key factor.

As we all know, the lack of sealing performance of fiber optic splice closure will lead to water vapor flooding, long-term existence of water will lead to attenuation of fiber attenuation or even broken fiber failure; in the cold winter, the water in the fiber optic splice closure is very easy to freeze and directly freeze the fiber .

Fiber optic splice closure sealing material selection:

Under normal circumstances, in order to achieve the sealing performance, the sealing material is soft and flexible, and the housing of the fiber optic splice closure is made of hard glue, and the linear expansion coefficients of the two are largely different. In the long-term use of hot and cold environment, the sealing material is easy to produce cross-linked aging, which leads to the failure of airtightness caused by the bonding force with the shell. At high temperatures, the pressure in the fiber optic splice closure becomes larger, and the seals soften to varying degrees. In the high-pressure softening state, the weak parts of the seals are easily broken; at minus 40 degrees Celsius, the sealant materials are hardened and lose their elasticity. The amount of deformation far exceeds the amount of deformation of the shell, creating a slight gap between the shell and the seal.

Therefore, to ensure the gas sealing reliability of the fiber optic splice closure, the sealing material should meet the following requirements: good thermal stability, appropriate mechanical properties, and adequate anti-aging properties.
