Operating Points

Prepare Cable:
- Select the appropriate cable.
- Strip and remove outer and inner protective layers and relax tubes.
- Clean and remove jelly filling.
- Reserve 1.1–1.6 m of fiber and 30–50 mm of steel core.
Secure Cable:
- Use cable clamps to fix the cable and core columns.
- For diameters < 10 mm, wrap the fixing area with self-adhesive rubber tape until the diameter reaches 12 mm.
Splice Preparation:
- Guide the fiber into the splice tray.
- Place heat shrink and hot-melt tubes on fiber pairs.
- After splicing, position the protective tubes and secure with stainless or quartz core columns.
- Heat the protective tubes to fuse them with the fiber.
- Snap the protective connector into the cable pathway (each tray supports up to 24 cores).
Organize Fibers:
- Distribute remaining fibers evenly in the splice tray.
- Secure fibers with nylon ties.
- Typically arrange splice trays from bottom to top.
- Place and secure the cover atop the splice tray post-splicing.
Ground Wire Installation:
- Install the ground wire per engineering specifications.
Seal the Closure:
- Wrap sealing tape around the entry ports.
- Insert sealing lines into grooves along the shell edge.
- Close the shell halves and tighten stainless steel bolts symmetrically.
Final Installation:
- Position and fix hangers based on laying requirements.
- Install the closure.
