Fiber optic cable manufacturers remind you of the precautions when selecting fiber optic cables! In addition to the number of cores and type of optical fiber, the selection of optical fiber cables also depends on the use of the optical fiber. The following points should be paid attention to when selecting: 1. When the optical cable is directly buried outdoors, armored optical cables should be selected. , when overhead, you can use two or more reinforced black plastic outer sheathed optical cables.
2. When selecting optical cables used in buildings, attention should be paid to their flame retardant, toxic and smoke characteristics. Generally, in pipes and forced ventilation areas, flame retardant and smoke-containing types can be selected. Flame-retardant, smoke-free and non-toxic types should be used in the environment.
For vertical wiring in the third floor, layer-twisted optical cables can be used; for horizontal wiring, branch optical cables can be used.
4. Multi-mode optical cables can be used for transmission distances within 2km; relay or single-mode optical cables can be used for transmission distances exceeding 2km.
The above are just a few issues that should be considered from the perspective of application. They need to be flexibly grasped during implementation. In fact, the wiring environment is complex and diverse, and various problems may arise at any time, which requires us to be careful in planning and During construction, we must strictly follow the wiring standards. If we encounter problems, we can analyze them flexibly and solve them satisfactorily.
