Abstract
The utility model provides a self-supporting round leading-in cable. The self-supporting round leading-in cable comprises a cable body and a supporting part. The cable body comprises an optical fiber, and the outside of the optical fiber is sequentially coated with a coating layer, a tightly-sleeving layer and a reinforcing layer. The supporting part is a suspension steel wire. An integrated sheath wraps the reinforcing layer and the suspension steel wire. By adopting the self-supporting round leading-in cable with the structure, strength of the cable can be guaranteed, meanwhile, erection of the cable in the air is achieved and use is convenient.
Description
Technical field
The utility model relates to the communications optical cable field, specifically, relates to a kind of circular leading in cable of the built on stilts self-bearing type that lays that is used for.
Background technology
FTTH (Fiber To The Home) is as the term suggests be exactly that an optical fiber is directly to family.Specifically, FTTH is meant optical network unit is installed in household user or enterprise customer place.The remarkable technical characterstic of FTTH is the bandwidth that not only provides bigger, and has strengthened the transparency of network to data form, speed, wavelength and agreement, has relaxed requirements such as environmental baseline and power supplies, has simplified and has safeguarded and installation.
At present, the system of laying of optical cable mainly contain in the pipeline lay, ground Yan Qiang lays and lay several kinds of modes in the air.Development along with optical fiber is registered one's residence also increases for the optical cable demand fast.For adapting to the different use occasions of optical cable, can reach the performance of each side to guarantee optical cable, select self-support cable when laying for use built on stilts usually, but existing self-support cable intensity is not high.
The utility model content
The technical matters that the utility model will solve is, to the deficiency that existing optical cable exists, provides a kind of self-bearing type circular leading in cable, and it can set up and can guarantee the intensity of optical cable in the air.
For solving the problems of the technologies described above; The technical scheme that the utility model adopts is: the circular leading in cable of a kind of self-bearing type; Comprise optical cable and support member, wherein said optical cable comprises optical fiber, and optical fiber is enclosed with coat, tight sleeve layer and enhancement Layer outward successively; Said support member is the messenger wire steel wire, and said enhancement Layer and messenger wire steel wire are wrapped with the integral type sheath.
Preferably, said sheath is the low smoke and zero halogen sheath.
Preferably, said optical fiber is the G657A bend insensitive optical fiber.
Preferably, said messenger wire steel wire is a sub-thread stainless steel steel wire.
Preferably, said sheath is the figure of eight.
Implement the circular leading in cable of self-bearing type of the utility model; Has following beneficial effect: adopt the integral type jacket structure; Optical cable partly is provided with coat and tight sleeve layer etc. simultaneously; Can guarantee that the circular leading in cable of this self-bearing type realizes setting up in the air when satisfying the optical cable requirement of strength, greatly facilitate and use and be convenient to carrying.The sheath of low smoke and zero halogen material, the fire-retardant requirement of optical cable in the time of can guaranteeing to register one's residence.The G657A bend insensitive optical fiber, bending strength is high.
Description of drawings
To combine accompanying drawing and embodiment that the utility model is described further below, in the accompanying drawing:
Fig. 1 is the cross section structure synoptic diagram of the utility model.
Among the figure, 1, optical fiber; 2, coat; 3, tight sleeve layer; 4, enhancement layer; 5, messenger wire steel wire; 6, sheath.
Embodiment
For the purpose, technical scheme and the advantage that make the utility model is clearer, below in conjunction with embodiment and accompanying drawing, to the utility model further explain.
As can be seen from Figure 1, the circular leading in cable of the self-bearing type of the utility model comprises optical cable and support member, and optical cable comprises optical fiber 1, and optical fiber 1 is coated with coat 2, and coat 2 is coated with tight sleeve layer 3, the tight sleeve layer 3 outer enhancement layers 4 that coat.Support member is a messenger wire steel wire 5, and messenger wire steel wire 5 is a sub-thread stainless steel steel wire.Support member is connected through the integral type sheath 6 of enhancement layer 4 with messenger wire steel wire 5 outsides parcel with optical cable, and this sheath 6 can be the figure of eight.Sheath 6 adopts the sheath of low smoke and zero halogen materials, can satisfy fire resistance preferably, satisfies outdoor fire-retardant requirement of going into when indoor optical cable.The G657A bend insensitive optical fiber, bending loss is insensitive, can guarantee the bending strength requirement of optical fiber.
More than show and described ultimate principle of the utility model and the advantage of principal character and the utility model.The technician of the industry should understand; The utility model is not restricted to the described embodiments; The principle of describing in the foregoing description and the instructions that the utility model just is described; Under the prerequisite that does not break away from the utility model spirit and scope, the utility model also has various changes and modifications, and these variations and improvement all fall in the utility model scope that requires protection.The utility model requires protection domain to be defined by appending claims and equivalent thereof.
Claims (5)
1. the circular leading in cable of a self-bearing type; Comprise optical cable and support member, it is characterized in that: said optical cable comprises optical fiber, and optical fiber is enclosed with coat, tight sleeve layer and enhancement Layer outward successively; Said support member is the messenger wire steel wire, and said enhancement Layer and messenger wire steel wire are wrapped with the integral type sheath.
