Installing a Fiber Splice Closure efficiently and effectively requires attention to detail and adherence to specific procedures.

Here’s a structured guide to ensure optimal installation, protecting the integrity of your fiber optic network connections.

1. Fiber Preparation:

  • Remove the Cable Jacket: Begin by removing the outer jacket of the optical cable. If present, remove any shielding and armor, then peel back the layers to expose the loose tubes. Follow the cable manufacturer’s recommended procedures for this. Leave a 3-meter length of the cable for further preparation.
  • Clean and Abrade: Use a cleaning solution to clean the loose tubes and the strength member sheath. Remove any excess filling and abrade the outer cable jacket for about 150mm using provided sandpaper to ensure a clean surface for sealing.

2. Cable Installation in the Closure:

  • Select and Attach Sealing Rings: Choose sealing rings that match the cable’s outer diameter. Place two rings on the cable.
  • Insert the Cable: Position the cable into the designated entry hole of the closure.
  • Grounding: Connect and ground the cable’s shield layer.
  • Seal with Tape: Wrap self-adhesive sealing tape between the two sealing rings to align with the outer diameter of the rings, creating a sealed cable end.
  • Secure the Cable: Insert the sealed cable end into the closure and use a hose clamp to secure the cable to the base of the splice closure. Tighten the clamp to ensure stability.
  • Cable Identification: Secure a green nylon tie on the outgoing fiber cable and trim the excess. Use a blue nylon tie for the customer fiber cable, also trimming the excess.
  • Seal Unused Ports: For any ports not in use, seal them with provided plugs wrapped in sealing tape.

3. Fiber Splicing:

  • Fiber Management: Reserve 1.5 loops of fiber behind the tray, then wrap all remaining fibers within the closure.
  • Buffer Tubes: Use single-core buffer tubes for individual fibers and ribbon buffer tubes for ribbon fibers. Secure fibers at the tray entry with nylon ties, using different colors to distinguish between outgoing (green) and customer (blue) cables.
  • Fiber Splicing: Follow the specified method to splice fibers. Insert the splices into the slots of the splice tray, managing any excess length by coiling it within the tray.
  • Tray Closure: Place the lid over the splicing tray and press down to lock it into position.
  • Tray Stacking: Depending on the capacity required by the splice closure, stack the splice trays accordingly. Trays should be stacked in a way that adheres to fiber management, accessibility, and maintenance requirements. For instance, securely stack five trays by fastening the second and third, and third and fourth trays together as described. When maintenance is required, trays can be accessed like turning a page in a book.
