Abstract
The utility model relates to an easily-recognized tight tube optical fiber used in the fields of communication and information transmission. The easily-recognized tight tube optical fiber comprises an optical fiber and a tight tube layer clad out of the optical fiber, and is characterized in that the optical fiber tight tube layer is provided with one or two color strips integrated with the tight tube layer in a co-extrusion manner, the color of the color strip is different form the color of the tight tube layer, and the color strip is arranged along the vertical direction of the tight tube optical fiber. Beneficial effects comprise that 1. a plurality of tight tube optical fibers with different color strips are arranged in the same optical cable, the tight tube optical fibers are easy to recognize and distinguish while in use, branching connection is more convenient, and the tight tube optical fiber core number of the optical cable can be further improved when the tight tube optical fibers with the color strips and without the color strips are used together; and 2. the employment of a color strip structure can reduce the using amount of some pigments, thereby reducing the manufacturing cost of the tight tube optical fiber and the optical cable.
Description
Technical field
The utility model relates to a kind of tight tube fiber of being convenient to discern that is used to communicate by letter with field of information transmission.
Background technology
In recent years because the widespread adoption of FTTx engineering, tight sleeve optic cable is owing to have excellent mechanical property and house wiring that the dry type structure is used for the FTTx engineering in a large number or the connection between the terminal device.Existing tight tube fiber is outside an optical fiber, to extrude the tight sleeve layer of one deck macromolecular material and constitute; The tight sleeve layer appearance color of a tight tube fiber is same color; When many tight tube fibers are processed multicore especially the core number is greater than the tight tube fiber optical cable of 12 cores, only depend on the tight sleeve layer solid color to be difficult to distinguish many tight tube fibers.Existing solution is on the optical fiber tight sleeve layer, to spray different markers; But because the diameter of tight tube fiber own is less; The clear and legible marking of recognizing of spray printing on so thin footpath ink jet numbering machine is had relatively high expectations, and printing ink is also relatively poor at the surface adhesion of tight sleeve layer; Come off easily in the use, give and to use and identification has brought inconvenience.
The utility model content
The utility model technical matters to be solved is the deficiency that exists to above-mentioned prior art and proposes a kind of tight tube fiber of being convenient to discern.
The utility model is that the technical scheme that problem adopted of the above-mentioned proposition of solution is: include the optical fiber tight sleeve layer outer with being coated on optical fiber; It is characterized in that described optical fiber tight sleeve layer be provided with 1～2 with tight sleeve layer co-extrusion all-in-one-piece vitta, described vitta color and tight sleeve layer color are different and prolong tight tube fiber and vertically lay.
Press such scheme, described tight tube fiber external diameter is 0.6mm～1.2mm.
Press such scheme, described vitta is shape or shaped form linearly.
Press such scheme, described vitta width is 0.2mm～0.6mm.
Press such scheme, described tight sleeve layer and vitta are processed by PVC, LSZH or Hytrel material.
Press such scheme, the described optical fiber that is coated in the tight sleeve layer is quartz glass optical fiber.
Press such scheme, it is different with the tight sleeve layer color that 12 above vittas are varied in color, or the tight sleeve layer tight tube fiber different with the vitta colour match be coated in the oversheath, constitutes the tight tube fiber optical cable more than 12 cores.
The beneficial effect of the utility model is: many 1, that vitta is different tight tube fibers are installed in the optical cable; Make each bar tight tube fiber be easy to identification and differentiation during use; Difference continues more convenient, can further improve the tight tube fiber core number of optical cable when the band vitta with when not using jointly with the tight tube fiber of vitta; 2, adopt the vitta structure can reduce the consumption of some colorants, and therefore reduce the cost of manufacture of tight tube fiber and optical cable.
Description of drawings
The radial structure sectional view of an embodiment of Fig. 1 the utility model.
Fig. 2 the utility model is processed the radial structure sectional view of an embodiment of optical cable.
Embodiment
Further specify the embodiment of the utility model below in conjunction with accompanying drawing.
An embodiment of the utility model is as shown in Figure 1, includes quartz glass optical fiber 1, and the diameter of quartz glass optical fiber is 250um; Optical fiber coats tight sleeve layer 3 outward; Have 1 and tight sleeve layer co-extrusion all-in-one-piece vitta 2 on the described optical fiber tight sleeve layer, described vitta color is different with the tight sleeve layer color and prolong vertically laying continuously of tight tube fiber, and vitta is shape linearly; The width of vitta is 0.5mm, and the diameter of whole tight tube fiber is φ 0.9mm.
It is as shown in Figure 2 that the utility model is processed an embodiment of optical cable; This embodiment is a kind of 18 core multi-usage branched cables; Optical fiber 1 outer co-extrusion tight sleeve layer 3 and 1 continuous vitta 2 are processed the tight tube fiber of φ 0.9mm, and the color of tight sleeve layer can be 2～3 kinds in 18 tight tube fibers, and the color of vitta can be 5～12 kinds; Constitute the tight sleeve layer tight tube fiber different thus with the vitta colour match; 18 such tight tube fibers are stranded to together, put some aramid yarn 4 outward as reinforcement, extrude one deck sheath 5 at last and process branched cable.
