Duct Fiber Optic Cables
Duct Fiber Optic Cables used in urban areas, the pipeline laying environment is relatively good, so there is no special requirement for fiber optic cable sheathing, no armoring. The length of the laying section and the location of the splice point must be selected before the pipeline is laid. When laying can be used mechanical side guide or manual traction. The traction force of one traction should not exceed the allowable tension of the fiber optic cable. The material for making the pipeline can be selected according to the geography of concrete, asbestos cement, steel pipe, plastic pipe, etc.
