All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to fall within the scope of the utility model.
FIG. 1 is a schematic view of a flat light-emitting fiber identification fiber cable according to a preferred embodiment of the present utility model, comprising a fiber optic ribbon 1, and a flat reinforced inner protection component 2 and a flat light-emitting outer protection component 3 sequentially disposed outside the fiber optic ribbon 1; the flat reinforced inner protection component 2 comprises a flexible reinforcing layer 21 and a flame-retardant inner sheath 22 which are sequentially wrapped outside the optical fiber ribbon 1; the flat light-emitting outer protective component 3 comprises a transparent outer protective sleeve 31 and a plurality of light-emitting optical fiber units 32 uniformly distributed in the transparent outer protective sleeve 31.
The number of optical fibers of the conventional flat optical cable is small due to the self structure, and a plurality of optical cables are often required to be used simultaneously in construction requiring high-capacity transmission performance. The flat luminous optical fiber identification optical cable of the embodiment has the integral structure that an inner layer and an outer layer are arranged on the optical fiber ribbon 1, and firstly, the optical fiber ribbon 1 has high capacity communication capability and can meet the increasing use demands. Secondly, as the flat reinforced inner protection component 2 with an inner layer structure, a reinforced and flame-retardant protection effect is formed outside the optical fiber ribbon 1 by virtue of the flexible reinforcing layer 21 and the flame-retardant inner sheath 22 respectively, and certain flexible tensile property is maintained. The flat luminous outer protective component 3 serving as an outer layer structure is characterized in that the transparent outer sheath 31 with the luminous optical fiber units 32 is used for continuously constructing more excellent mechanical properties for the optical fiber ribbon 1 on the basis of the flame-retardant inner sheath 22, and the luminous performance is realized on the other hand, so that the problems of dark environment, large construction operation difficulty caused by disordered construction environment of a circuit and high maintenance cost of an optical cable can be solved.
In a further alternative implementation of the present embodiment, the light emitting optical fiber unit 32 includes a light emitting optical fiber 321 and a transparent tight-buffered layer 322 outside thereof.
In specific implementation, the light-emitting optical fiber unit 32 can use a single ytterbium-doped double-clad optical fiber, and the optical fiber adopts the MCVD rod making process and the drawing process which are the same as those of the active optical fiber, so that extremely low welding loss can be realized with the active optical fiber, and the application requirement of industrial-grade optical fiber laser astigmatism can be met.
In a further alternative implementation manner of this embodiment, the number of the light emitting fiber units 32 is four, and the light emitting fiber units are respectively arranged at four positions of up, down, left and right and close to the outer edge of the transparent outer sheath 31. Thus, the luminous identification can be ensured in four directions.
In a further alternative implementation manner of this embodiment, the transparent tight-sleeve layer 322 is a tight-sleeve layer made of TPU and having an outer diameter of 0.9 mm. The transparent TPU has a diffusing effect on the light of the luminescent fiber 321.
In a further alternative implementation manner of the present embodiment, a tear rope is further provided at the interface between the flexible reinforcing layer 21 and the flame retardant inner sheath 22.
In a further alternative of the present example, the tear cord is a 3000D tear cord.
In a further alternative implementation manner of this embodiment, the flexible reinforcing layer 21 is a structural layer wrapped by five pieces of 1420dtex aramid yarn. The structural layer can effectively protect the optical fiber ribbon 1 and can increase the tensile resistance of the optical cable.
In a further alternative of this embodiment, the optical fiber ribbon 1 comprises a glass fiber having a core count of 4, 6, 8, or 12. Compared with the plastic optical fiber commonly used in the prior art, the glass optical fiber has better stability and light transmission property, and the glass optical fiber which uses silicon dioxide as a main raw material can continuously emit light for a long distance after light is transmitted, so that the light-emitting effect is more excellent, and the later maintenance difficulty of construction cost can be further reduced. More specifically, the glass fiber may be a G657A2 fiber, and the G657A2 fiber is stronger than other types of fibers in terms of tensile properties and red bend loss.
In a further alternative of the present example, the flame retardant inner sheath 22 is a low smoke, halogen free inner sheath. The sheath has extremely strong environment-friendly flame retardant property.
