Abstract
The invention provides a transparent cable which is difficult to discern and is easy for indoor wiring. The cable comprises a cable core. The outer ring of the cable core is coated from inside to outside with a cladding layer, a coating layer and a protecting layer successively. The coating layer and the protecting layer are made of transparent material. The coating layer is made of UV-curable acrylate resin. The protecting layer is made of transparent thermoplastic elastomer. The number of the cable core is one. Due to the light self-weight, wiring can be performed by bonding with glue. The wiring is quick and easy and produces little noise disturbance. The influence on wall body by the wiring method is reduced to the minimum so that the disturbance on users is reduced to the minimum. The user acceptance level is high. Thus, the resistance and difficulty of indoor wiring of service providers are greatly reduced and a multi-win effect is achieved.
Description
Technical field
The present invention relates to a kind of cable, particularly a kind of transparent invisible cable being easy to house wiring.
Background technology
Along with the development of Fibre Optical Communication Technology, and optical fiber, the continuous maturation of communication periphery industrial chain and perfect, the scale of fiber optic communication network constantly expands, in recent years, telecom operators build FTTH network on a large scale, meanwhile, there is a large amount of group customer and normal client access problem.Tradition leading in cable, when indoor undercut wiring, has showed good advantage; If but user does not reserve tube seat or hidden pipe in advance, then when house wiring, how the effectively attractive in appearance indoor environment that incorporates does not destroy the attractive in appearance of the overall decoration of user or group customer office space to optical cable, becomes a difficult point, in work progress, the very possible construction speed affecting entirety because of obstructing of user, or take this mode and bring no small impact to the security of cable.Traditional indoor leading in cable is used on a large scale by user in the construction of FTTH broadband, and test proves that it can introduce section and indoor use really, if but fiber entering household, the drawback that traditional indoor leading in cable also exists.
First, traditional indoor leading-in optical cable diameter is comparatively thick, and conventional inside cable radius is about about 2mm-3mm.Secondly, mainly use pe sheath or low-smoke non-halogen flame-retardant polyene through sheath with cable outer sheath in conventional chamber, sheath is thicker, sheath color is also comparatively obvious, main with black or yellow, particularly obvious in house wiring, and, after optical cable is opened and dialled sheath, the painted coating layer of optical fiber can destroy indoor overall appearance for the user that reserved undercut does not connect up in advance.Again, traditional inside cable is due to the restriction of structure and shape, and itself also exists stiffener, and its bending radius is relatively little, and bending resistance is bad, and anti-torsion and the ability that deflects also poor.In addition, traditional indoor optical cable due to own wt larger, when indoor are laid, need to adopt and follow closely solid traditional system of laying along wall, difficulty of construction is relatively large, for user, adopt the solid mode of nail also to destroy the integrality of indoor wall, this is the thing perplexed very much concerning many users, and this also becomes in Operator Specific Service evolution, there is a link of contradiction between Construction Party and user, also become the key factor that restriction Operator Specific Service is expanded.Therefore, be badly in need of a kind of new indoor wiring optical cable of research and development, put the puzzlement of dress cable to effectively solving or alleviating old community user transformation and government and enterprises' building in FTTH builds to a certain extent.
Summary of the invention
Goal of the invention: technical matters to be solved by this invention is for the deficiencies in the prior art, provides a kind of transparent invisible cable being easy to house wiring.
In order to solve the problems of the technologies described above; the invention provides a kind of transparent invisible cable being easy to house wiring; comprise cable core, the outer ring of described cable core is coated with covering, coat and protective seam from inside to outside successively, and described coat and protective seam are transparent material and make.
In the present invention, described coat is ultraviolet curing acrylic ester resin.
In the present invention, described protective seam is the protective seam that transparent thermoplastic elastic body is made.
In the present invention, described cable core number is a core.
In the present invention, the thick 125um of described covering.
In the present invention, described coating thickness 250um.
In the present invention, described protection thickness 900um.
Beneficial effect: 1, diameter of the present invention is little, the thin about 1.6mm-2.1mm compared to traditional inside cable cable footpath, and optical cable entire body is close to transparent, the good concealment when house wiring;
2, because cable jacket adopts transparent thermoplastic elastic body, cable bend radii is little, is very applicable to indoor inner corner trim or the wiring of external corner place;
3, optical cable deadweight is lighter, glue can be adopted to cohere can connect up, connect up efficient and convenient, basic noiselessness interference, and wire laying mode is also decreased to minimum to wall influence, thus minimally can bother user, user's acceptance is high, thus resistance and the difficulty of operator's house wiring can be reduced to a great extent, reach the effect of multi-win.
