Abstract
The utility model discloses a self-supporting micro optical cable used in a sewage pipe, comprising an optical cable main body made of the optical fiber bundles and a stainless steel tube with fiber ointment filling inside which holds the optical fiber bundles. The utility model also comprises a bearing carrier axially extending along the optical cable main body and an 8-shaped Polyethylene sheath coating the optical cable main body and the bearing carrier. The utility model can solve the problems of waterproof, anticorrosion, rodent resistance and other problems and effectively protect the inner optical fiber when bearing the side pressure and bending deformation. All the optical fiber units of the optical cable are not easily affected by the longitudinal tension after being laid so that the optical cable has the long service life. The utility model also avoids the installation mode of the traditional non self-support optical cable that clamps must be arranged in every certain distance, thereby greatly lowering the laying difficulty.
Description
Technical field
The utility model relates to a kind of product that is used for the optical communication transmission field, relates in particular to a kind of self-bearing type micro optical cable.
Background technology
Along with the arrival of information age, the conveying capacity of information becomes explosion type ground to increase.As the effective means of high capacity, long Distance Transmission, optical fiber cable has obtained a large amount of application.The application of optical cable is also developed to Metropolitan Area Network (MAN), Access Network direction by long distance line gradually.The development of industry is promoting development of technology, and new cable configuration is constantly released, and new technology constantly is applied.
Following water/storm sewer is to improve the most in the world at present and intensive urban pipeline network, provides the wide space that utilizes for building the communication network.Its environmental baseline of laying optical cable is comparatively abominable in Xia Shui/storm sewer, and, lay by the needs of pipe dredging because must hanging, this just requires to use the optical cable product in this occasion must can bear bigger pulling force than common little cable on the one hand, on the other hand, also require optical cable that waterproof, corrosion-resistant and intensive properties are preferably arranged, and the still difficult above-mentioned requirements that adapts to of the various optical cables of existing structure.If use traditional non-self-support cable, then need to adopt the Installation Modes that must add clip every a determining deviation in addition, it is higher to lay difficulty
Summary of the invention
For overcoming the defective of above-mentioned prior art, technical problem to be solved in the utility model is intended to provide a kind of waterproof, corrosion resistant, intensity higher, and can reduce the self-bearing type micro optical cable that lays difficulty and be applicable to sewer pipe.
For solving the problems of the technologies described above, the utility model proposes a kind of self-bearing type micro optical cable that is used for sewer pipe, comprise the optical cable main body that constitutes by the stainless-steel tube that is filled with fine ointment in fibre bundle, the described fibre bundle of containing, also be provided with and prolong the axially extended supporting body of described optical cable main body, coat " 8 " font PE sheath of described optical cable main body and described supporting body.
Described supporting body is the steel strand wires with high elastic modulus, says further, can be the galvanized strand wires with high elastic modulus.On this basis, can also extrude on the PE sheath top layer that coats optical cable main body outer rim and be useful on the colored indicators vitta that the quick identification optical cable is used.
After adopting said structure, because the optical cable main body is by the supporting body supporting of the figure of eight, thereby the tension force bearing part of optical cable and optical cable main part are kept apart, and under cable body vacant state, each fiber unit in the optical cable main body is subjected to any pulling force longitudinally hardly; What adopt outside optical fiber simultaneously is the fabulous stainless-steel tube of high strength and sealing, can effectively protect inner optical fiber when optical cable bears side pressure and flexural deformation, for the high quality optical fiber transmission provides guarantee; In addition, the setting of the supporting body of this figure of eight has also avoided traditional non-self-support cable must add the Installation Modes of clip every a determining deviation, lays difficulty thereby reduce greatly.
To and be elaborated to the utility model in conjunction with the accompanying drawings by embodiment below.
Description of drawings
Fig. 1 is the cross-sectional structure synoptic diagram of self-bearing type micro optical cable described in the utility model.
Embodiment
With reference to Fig. 1, the self-bearing type micro optical cable that is used for sewage or storm sewer described in the utility model, comprise by fibre bundle 11, contain this bundle optical fiber in be filled with the optical cable main body 1 that the stainless-steel tube 13 of fine ointment 12 constitutes, for having improved the tensile strength of optical cable, make the utility model can be applicable to the laying in urban sewage/storm sewer preferably, the utility model also is provided with and prolongs described optical cable main body 1 axially extended supporting body 2, and optical cable main body 1 and supporting body 2 coat, link together by " 8 " font PE sheath 3.Supporting body 2 the problems such as waterproof, anticorrosion and protection against rodents that can solve on the one hand optical cable preferably are set, on the other hand, also make product can bear bigger pulling force than common little cable, avoided traditional non-self-support cable must add the Installation Modes of clip simultaneously, laid difficulty thereby reduce greatly every a determining deviation.
Above-mentioned supporting body 2 can adopt the steel strand wires with high elastic modulus shown in Figure 1, says further, can be the galvanized strand wires with high elastic modulus.
On this basis, can also extrude on the PE sheath top layer that coats optical cable main body outer rim and be useful on the colored indicators vitta 4 that the quick identification optical cable is used.This colored indicators vitta can extrude simultaneously in the manufacturing process of PE (tygon) sheath according to user's specific requirement and form.
The utility model is adapted in the pipeline, especially directly hangs in sewage or the storm sewer to lay and need not to set up in addition messenger wire and swing pipe, and once construction can be finished, and the system engineering cost is low; The application of stainless-steel tube 13 can guarantee serviceable life of optical cable, has satisfied the various abominable working condition of laying optical cable in storm sewer or sewer line preferably.Because storm sewer or sewer line network extend in all direction, optical cable described in the utility model can be used as the effective solution of " last kilometer " communication network development.
