The FTTR (Fiber to the Room) invisible fiber optic cable duct wiring solution is a key step in achieving whole-house Gigabit and 10-Gigabit connectivity, particularly for retrofitting in already decorated spaces. Its core lies in combining invisible fiber optic cables with ducts to balance high-speed performance, aesthetics, and ease of installation.
1. Invisible Fiber Optic Duct
Tape-type invisible fiber optic ducts are flexible channels used for concealed installation of invisible fiber optic cables. They feature a self-adhesive design, offering ultra-thin, transparent, and anti-aging properties. Suitable for walls, baseboards, ceilings, and other surfaces in homes, offices, and commercial spaces, they ensure both aesthetic appeal and physical protection for fiber optic wiring.
