There are mainly three types of optical fiber jumpers according to the termination types: ST-ST, SC-SC, and ST-SC. According to the type of optical fiber, there are mainly two types: single-mode optical fiber and multimode optical fiber. The specifications of jumper length are 0.5m, 1m, 2m, 3m, 5m, 10m, etc. According to the material of cable outer sheath, it can be divided into ordinary type, ordinary flame retardant type, low smoke zero halogen type (LZSH), low smoke zero halogen flame retardant type, etc.
Corresponding measures shall be taken for the generic cabling system according to the building fire rating and fire resistance requirements for materials. Flame retardant cables and optical cables shall be used for laying cables or optical cables in flammable areas and building shafts; Flame retardant, low smoke and low toxic cables or optical cables should be used in large public places; Flame retardant wiring equipment shall be used in adjacent equipment rooms or handover rooms.
