Fiber jumper types are divided into three types: St-St, SC, St-Sc. According to the types of optical fiber mainly have single-mode fiber and multimode fiber two types. Jumper length specifications are 0.5m, 1m, 2m, 3m, 5m, 10m and so on. According to the cable outer layer material can be divided into common type, ordinary flame-retardant type, low smoke halogen-free (Lzsh), low smoke halogen-free flame-retardant type.
According to the building fire protection grade and the fire resistance requirement of the material, the integrated wiring system should take corresponding measures. The use of flame-retardant cables and optical cables should be used in the flammable area and in the shaft of the building, and the flame-retardant, low smoke and low toxicity cable or cable should be used in large public places, and the flame-retardant wiring equipment should be used in adjacent equipment or between interfaces.
