Types and Installation of Fiber Optic Splice Closures

Type of fiber optic splice closures

Horizontal fiber optic splice closures

  • 432-core horizontal fiber optic splice closures

Can be used for straight and branch (one in two, one in three) connection of various types and structures of optical cables within a diameter of 22mm (φ), whether they are aerial, pipeline, underground, or well-laid. It is also suitable for connection of full plastic city power cables.

  • Features of 432-core horizontal fiber optic splice closures

The junction box is made of high-strength imported engineering plastic (ABS) and molded with modeling material under high pressure.

The body is sealed with silicone rubber and the cable inlet is made of silicone block, which is reliable and easy to open and maintain.

4 in and 4 out, maximum capacity of 432-core (single fiber).

The external metal parts and fixing devices are made of stainless steel, so they can be reused in different environments.

Dome fiber optic splice closures

  • 216-core dome fiber optic splice closures

Used to protect the fiber optic joints between two or more optical cables, for direct or branching connections, to prevent aging caused by heat, cold, light, oxygen, and microorganisms in nature.

  • Features of 216-core dome fiber optic splice closures

Antenna and wall mounted.

Protection level: IP68.

In-line or cup type.

Optional 2 in and 2 out, 3 in and 3 out, 4 in and 4 out, etc.

Withstand earthquake or pressure.

Installation instructions of fiber optic splice closures

1. Ensure that the cable length inside the housing and the lead-out length are sufficient.

a——Cable fixed length;

B——Cable length with sheath inside the housing;

c——Length enclosed in the closed body;

d—Length of branch cable.

2. Use a pipe cutter and longitudinal stripping pliers to strip off the cable sheath outside. The length depends on the above instructions or usage conditions.

3. Cut the cable port with a hacksaw (the recommended position for hacksaw cutting is about 10.0 to 20.0mm from the tip of the cable port), and then open the cable port.

4. Thread the stripped optical cable through the heat shrink tubing and close the optical cable port as required.

5. Use a cable fixing column to fix the cable strengthening core.

6. Place the stripped optical fiber into the optical fiber splicing tray for splicing and storage.

Factors to consider when choosing fiber optic splice closures

  • According to the use environment, choose aerial, direct burial, pipeline or underwater optical cable joint box.

  • According to the structure of the optical cable used, process the corresponding optical cable joint box.

  • According to the network structure, whether the installation function with splitter is needed.

  • According to the type of optical fiber, choose single-core or ribbon splicing tray.
