2025-10-01

Tools Needed for Installation

Invisible FTTH fiber optic cable
Handheld hot melt glue gun or adhesive tool
Specialized hot melt glue sticks
Corner protectors (for bends)
Cleaning cloth
Fiber optic connectors or quick connectors
Wire strippers and scissors

Step-by-Step Installation ProcessRoute Planning

Plan the cable route

along wall corners, skirting boards, door and window frames—places that are visually discreet. Avoid areas prone to damage or high temperatures.

Surface Cleaning

Clean the wall surface or skirting boards along the planned route thoroughly to remove dust, grease, or moisture that could affect adhesion.

Cable Preparation

If necessary, strip the outer protective layer to expose the invisible micro-cable inside. Some invisible cables, such as butterfly-type ones, may require removing their protective layers beforehand.

Tool Preparation

Insert the invisible cable into the designated slot of the hot melt glue gun or adhesive tool. Insert glue sticks and preheat the tool to the proper temperature.

Cable Adhesion and Fixing

Slowly and evenly advance the tool to apply the cable along the planned route. Use corner protectors on bends to maintain a minimum bending radius of about 5mm. Press the cable firmly to ensure close adhesion.

Cable Termination

After finishing the laying, connect the cable end to the terminal device using quick connectors or cold connectors. Alternatively, fusion splicing can be performed on site if equipment is available.

Inspection and Testing

Check the cable for firmness, neatness, and quality of adhesion along the wall. Test the fiber optic link to ensure signal transmission is stable and meets standards.
