Proper mounting is essential for the longevity and reliability of the fiber optic network.

Installation Process

Tools and equipment needed

Installing a horizontal fiber optic splice closure requires specific tools and equipment. Technicians need fiber optic splicing tools, such as cleavers and fusion splicers. They also require sealing materials, like heat-shrink tubes or mechanical seals. Additionally, mounting brackets and screws are necessary for securing the closure. Having the right tools ensures a smooth installation process.

Step-by-step guide

1. Preparation: Gather all necessary tools and materials. Ensure the work area is clean and organized.
2. Cable Preparation: Strip the outer jacket of the fiber optic cable. Clean the fibers to remove any debris.
3. Splicing: Use a fusion splicer to join the fiber ends. Ensure the splices are secure and free from defects.
4. Sealing: Place the spliced fibers inside the closure. Use sealing materials to protect against moisture and dust.
5. Mounting: Secure the closure using appropriate mounting techniques. Ensure it is stable and accessible for future maintenance.
6. Testing: Perform tests to verify the integrity of the splices. Ensure the network operates efficiently.

“Consider how easy it is to install and if it allows re-entry for future maintenance,” advises a Technician deploying fiber optic for Swisscom. This insight highlights the importance of choosing closures that facilitate both initial installation and future access.
