A Deep Understanding of Fiber PLC Splitter


The cables are physically attached to the Fiber PLC Splitter to provide strain relief. The cables normally enter the tray on one side only to facilitate moving the tray/joint enclosure to a more accessible jointing location. The fibers are looped completely around the tray to provide slack, which may be required to accommodate any changes in the future, and also to provide tension relief on the splices. Each splice joint is encased in a splice protector (plastic tube) or in heat shrink before it is clipped into the holder. In addition, fiber splice trays are available with patching facilities. This allows different fibers to be cross-connected and to be looped back for testing purposes.

When using fiber splice tray, skill is needed in order to guarantee a good performance. Here are some tips on it.

1. Ensure the color, loose tube and the fiber number following in the exact sequence specified by the manufacturer.

2. The proper length of fiber is needed to allow splicing and then neatly storing fiber in the fiber splice tray.

3. Cables with metallic shielding or strength members must be properly grounded and bonded.

4. Care should be taken when arranging fibers and splices in splice trays and buffer tubes in the splice closure to prevent stress on the fibers.

5. Arranging fibers inside fiber splice trays may require twisting the fiber but following the manufacturer’s instructions will minimize the stress on the fiber.

6. Cables must be secured to the splice closure and sealed properly.

7. Loose tube cables will have the tubes extending from the entrance of the closure to the tray, where they are secured, then approximately 1 meter of bare fibers are organized in the tray after splicing.

8. Care must be taken to properly bond electrical conductors such as the armor on some cables or center metallic strength members to the closure and at each end.

9. All closures must be sealed to prevent moisture entry.
