Overview

So far, we talked about fiber optic splice closure, about its definition, usage, structures and classification. We know that the fiber optic splice closure is waterproof and dustproof, but this are just too blurry when introducing its standards, so in this article we are going to help you learn more about its standards.
 

What are the fiber optic splice closure standards?

The fiber optic splice closure standards are a serious of requirements that needs to be reached, otherwise it’s defective. For example, the fiber optic splice closure must be waterproof otherwise leaks will cause network disconnection.
 
First, let’s get start with general properties. the general properties are just basics standards that a fiber optic splice closure should be considered when they are designed:
  1. The fiber optic splice closure shall be able to restore the integrity of the cable sheath and the mechanical continuity of the cable reinforcement members.
  2. The fiber optic splice closure shall be able to provide the functions of electrical connection, grounding or disconnection of the metal components.
  3. The fiber optic splice closure shall be able to protect the inner components from environments.
  4. The fiber optic splice closure shall provide the space for remaining part of optical fiber.
  5. The fiber optic splice closure shall be able to resist termite when needed.
 
For both mechanical and sealing property standards, the actual sealing behavior can only be examining by tests:
 
Sealing property requirements. After a fiber optic splice closure mounted properly, and filled in (1005) kPa air pressure, submerge fiber optic splice closure in the water for 15min at room temperature, if no bubbles pop up or the barometer index remain unchanged for 24h, means it has passed.
 
Mechanical property requirements. The mechanical property refers to different mechanical characteristics of materials under different environments (such as temperature) and under various external effects (stretching, compression, bending, torsion, impact, etc.).
