Taihan’s loose tube jelly-filled type optical cables for duct are ideal for duct installation by minimizing the outer radius while improving tensile strength and flexibility. The cables manufactured with jelly-compound anti-humidity layer and sheath take into account external environmental change so that it can withstand extreme weather conditions. In addition, its excellent mechanical properties enable the cables to maintain integrity and last longer.
