How to install a dome type fiber splice closure in manhole?

Fiber optic cables are becoming increasingly popular for telecommunication and networking purposes because of their superior performance in comparison to traditional copper wires. However, to ensure optimal signal transmission, it's essential to protect and manage the fiber cables, which is where fiber splice closures come in. In this article, we'll discuss how to install a dome type fiber splice closure in a manhole.

Step 1: Prepare the work area

Before you start working, ensure that the manhole is clean and free of debris. The closure should be installed on a flat surface, so make sure the area is level. Ensure that there is sufficient lighting, ventilation, and safety equipment such as gloves and safety glasses.

Step 2: Unpack the fiber splice closure kit

The dome type fiber splice closure kit typically contains the following components:

Dome type closure body

Splitter tray (optional)

Cable gland (for cable entry)

Cable tie

Sealing tape

Installation manual

Make sure all the components are present and in good condition before proceeding.

Step 3: Install the cable gland

Insert the cable gland through the pre-drilled hole in the closure body. Tighten the nut of the cable gland to secure it in place. Ensure that the cable gland is aligned with the cable entry point.

Step 4: Prepare the fiber cables

Strip off the outer jacket of the fiber cables and cut the strength members to the required length. Ensure that the fiber cables are clean and free of any debris or sharp edges.

Step 5: Splice the fiber cables

Place the splitter tray (if included) in the closure body. Follow the instructions provided in the manual to splice the fiber cables. Ensure that the fibers are properly cleaned and aligned before splicing.

Step 6: Organize the fibers

After splicing, organize the fibers and place them in the designated slots or trays. Ensure that there is no excess fiber slack and that the fibers are not tangled.

Step 7: Seal the closure

Place the closure body over the cable gland and ensure that it fits snugly. Use the sealing tape provided in the kit to seal any gaps between the closure body and the cable gland. Ensure that the sealing tape is applied evenly and covers the entire circumference of the closure.

Step 8: Secure the closure

Use the cable tie provided in the kit to secure the closure body to the manhole. Ensure that the closure is securely fastened and does not move.

Step 9: Test the fiber cables

Test the fiber cables using an OTDR (Optical Time Domain Reflectometer) or other suitable testing equipment to ensure that they are properly spliced and working correctly.

In conclusion, installing a dome type fiber splice closure in a manhole requires careful preparation and attention to detail. Following the steps outlined above will help ensure a successful installation, protecting and managing fiber optic cables for optimal performance.
