Special Optical Cables

Special communication optical cable is purpose-built for special operating conditions. Unlike ordinary indoor/outdoor cable, its structure is customized to the application environment. Types include flame-retardant, armored, rodent-resistant, submarine, tactical (field) and low-temperature aerial cable. Through metal armoring, water-blocking compounds and special jackets, it delivers enhanced resistance to pressure, water, gnawing by animals and extreme temperatures. With low-loss fiber units, it can adapt to harsh scenarios such as tunnels, mines, underwater and battlefield conditions. It is mostly used in rail transit, mining, offshore platforms, emergency communications and power engineering, ensuring stable optical signal transmission under extreme conditions.
