2. to make optical cable have an external diameter little for unique design, the characteristics of intensity height, good bending property, and have good environmental performance.
3. steel pipe extrudes double-deck PE sheath outward, and internal layer adopts special physical blowing technology to make optical cable have excellent anti-seismic performance, and oversheath adopts high-quality HDPE material to extrude, and the waterproof mildew-resistant has good resisting environmental stress and cracking ability.
Description of drawings
The utility model will be further described below in conjunction with drawings and Examples:
Fig. 1 is a structural representation of the present utility model.
Wherein: 1 sheath; 2 polyethylene foamed enhancement Layers; 3 steel pipes; 4 optical fiber.
Embodiment
Embodiment: as shown in Figure 1, a kind of road surface microflute metal optical cable comprises sheath (1), and the optical fiber (4) in the steel pipe (3) in the sheath (1), steel pipe (3) is provided with polyethylene foamed enhancement Layer (2) between described sheath (1) and the steel pipe (3).
It is little that the utility model unique design makes optical cable have an external diameter, the characteristics of intensity height, good bending property, and have good environmental performance.
The utility model is introduced advanced foreign technology, adopts the plasma welding connection technology to produce the high-strength stainless steel fiber unit, and the stainless steel tube wall can guarantee that the light unit radial blocks water.
In stainless steel band after-combustion drawing forming process, adopt accurately advanced surplus long control technology to make the optical fiber in the steel pipe have rational surplus length, guarantee that optical cable has good temperature performance.
Steel pipe of the present utility model extrudes double-deck PE sheath outward, and internal layer adopts special physical blowing technology to make optical cable have excellent anti-seismic performance, and oversheath adopts high-quality HDPE material to extrude, and the waterproof mildew-resistant has good resisting environmental stress and cracking ability.
The utility model also can be placed fibre ribbon as required in beam tube, make the optical cable of bigger core number.
The pipe inner fiber adopts whole chromatogram identification when fiber count is no more than 12 cores, and its color meets Mang Saier international standard chromatogram; When fiber count surpasses 12 cores, dose colour circle on the colored optical fiber surface, be convenient to carry out the identification and the termination of optical fiber.
The utility model is a kind of novel central beam tube type metal optical cable, adopts unique design, makes optical cable have good shockproof properties, favorable mechanical performance, environmental performance, and compact conformation, external diameter little, can cut microflute in road surface and lay use.This optical cable is totally with low cost, and is easy to use, for each telecom operators provides a kind of brand-new solution.
