Abstract
The present utility model relates to a rubber-covered optical cable. The cable is composed of an optical fiber, and reinforcing cores which are arranged on the two sides of the optical fiber and are parallel with the optical fiber. The optical fiber and the reinforcing cores are all wrapped by a sheath, a sleeve-tightening layer for protecting the optical fiber is arranged between the optical fiber and the sheath, and the optical fiber is tightly wrapped by the sleeve-tightening layer. In the cable, the sleeve-tightening layer which is tightly covered on the optical fiber and used for protecting the optical fiber is arranged between the optical fiber and the sheath, thus the optical fiber can be well protected after the sheath is stripped or abraded, and the optical fiber is not easily broken or damaged.
Description
Technical field
The utility model relates to a kind of covered wire cable.
Background technology
Along with the FTTH development of internet technology; The butterfly leading in cable of existing standard YD/T1997-2009 standard is mainly used in user's section of introducing of FTTH lightguide cable link; In at present domestic FTTH engineering, paid close attention to, be commonly called as " covered wire cable " on the market, because the FTTH development rapidly; This cable configuration is perfect not to the utmost; Granted publication day be on February 18th, 2009 Granted publication number for the patent document of CN201196693Y discloses a kind of 8 font covered wire cables, comprise optical fiber, be positioned at the strengthening core that optical fiber both sides and optical fiber laterally arrange, said optical fiber and said strengthening core are wrapped in the sheath together.In use, after sheath is peeled off or worn and torn,, very easily fracture and damage because optical fiber is very crisp.
Summary of the invention
The purpose of the utility model is to provide a kind of covered wire cable, to solve the problem that optical fiber fractures easily and damages after sheath is peeled off or worn and torn in the prior art.
In order to address the above problem; A kind of covered wire cable of the utility model; The strengthening core that comprises optical fiber, is positioned at the optical fiber both sides and laterally arranges with optical fiber; Said optical fiber and strengthening core all are wrapped in the sheath, between optical fiber and sheath, also are provided with the tight sleeve layer that is used to protect optical fiber, and this tight sleeve layer closely is coated on the optical fiber.
Said fibre diameter is 250 μ m, and described tight sleeve layer external diameter is 500-600 μ m.
Described optical fiber is quartz glass optical fiber.
This covered wire cable is 8 font structures, and its contour structure size meets the regulation of table 2 among the YD/T 1997-2009 " Access Network is used the butterfly leading in cable ".
The utility model closely is coated on the tight sleeve layer that is used to protect optical fiber on the optical fiber through between optical fiber and sheath, being provided with, and makes after sheath is peeled off or worn and torn, also can protect optical fiber well, makes optical fiber not frangible and damage.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
Embodiment
Below in conjunction with accompanying drawing present embodiment is described in detail:
As shown in Figure 1, a kind of covered wire cable, this covered wire cable are 8 font structures; Comprise that diameter is the optical fiber 1 of 250 μ m, the strengthening core 2 that is positioned at optical fiber 1 both sides and laterally arranges with optical fiber 1; Said optical fiber 1 is quartz glass optical fiber, and said optical fiber 1 all is wrapped in the said sheath 3 with strengthening core 2, between optical fiber 1 and sheath 3, also is provided with the tight sleeve layer 4 that is used to protect optical fiber 1; Described tight sleeve layer 4 external diameters are for being 500-600 μ m; This tight sleeve layer 4 closely is coated on the optical fiber 1, and wide in the cross-sectional shape size of this covered wire cable is 2.0mm, and long is 3.0mm.
