How can I ensure proper sealing and protection of the spliced fibers?

To ensure proper sealing and protection of spliced fibers in a cable splice closure, the following steps can be taken:

Preparations: Make sure the working environment is dry and tidy, and use cleaning tools to remove dust and dirt from splice boxes and optical fibers.
Verify Fiber Length: Make sure that the fiber length is sufficient to allow a fusion splice connection to be made within the splice closure without excessive strain or excessive bending.
Using the fusion splicer: According to the operating instructions of the fusion splicer, preheat the fusion splicer to an appropriate temperature, and place the end face of the optical fiber in the fusion splicing area.
Splicing optical fibers: Place the two optical fibers that need to be connected on the fiber holder of the fusion splicer, and start the fusion splicer for fiber splicing. Make sure that the fusion splicer completes the splicing program, and control the splicing time and splicing arc as needed.
Heat-shrinkable tube protection: After the fusion splicing is completed, put the heat-shrinkable tube on the splicing point, and heat it with a heat gun or a heat source, so that the heat-shrinkable tube tightly wraps the fiber connection. Make sure the heat shrink tubing is fully shrunk and provides adequate protection and sealing.
Verify Connection: Verify the quality and transmission performance of the fiber optic connection using a fiber optic tester or test equipment. Perform the necessary tests and measurements to ensure a reliable connection.
Sealed splice box: put the spliced optical fiber connection into the cable splice box, and ensure the sealing performance of the splice box. According to the design of the joint box, use corresponding seals, clips, or bolts for fixing to ensure the sealing and protection performance of the joint box.

What is the expected lifespan of the splice closure?

Generally speaking, high-quality optical cable splice closures can have a long and reliable lifespan, usually up to 10 years or longer.

The expected lifespan of an optical cable splice closure can be influenced by several factors, including quality, material, installation method, environmental condition, and maintenance.

However, the following factors may affect the lifespan of a fiber optic splice closure:

Material quality: Using high-quality materials (such as adding anti-UV materials) can enhance the durability, anti-aging and corrosion resistance of the splice box, so as to better extend its lifespan.

Installation environment: Harsh environmental conditions such as high temperature, humidity, dust, chemicals, etc. may have a negative impact on the performance and life of the splice box.

Maintenance: Regular cleaning, inspection and maintenance will prolong the life of the splice closure. Regular inspection and replacement of damaged seals, heat-shrinkable tubes and other components, as well as checking whether the shell is cracked or damaged, and whether water has entered is also the key to maintaining the performance of the joint box.

Operation and use: Correct operation and use, avoiding excessive brutal construction operations, can prolong the life of the joint box.
