Abstract
The utility model relates to a telecommunication optical cable, in particular to a flexible optical cable. The cable is provided with optical fibers and an external sheath as well as a spiral metal hose wound by sheet stainless steel, at least two optical fibers penetrate through the metal hose, and are tightly coated with buffer layers, a woven layer woven through steel wires or glass yarn is arranged outside of the metal hose, and the woven layer is coated with the external sheath. The cable has good bending and fire resistance properties, and is suitable for occasions such as houses, machine rooms and connection between equipment where a small bending radius is required.
Description
Technical field
The utility model relates to a kind of communications optical cable, relates in particular to a kind of flexible optical cable.
Background technology
Along with the development of FTTH technology and industry, various forms of inside cables have obtained developing rapidly.Compare with the communications optical cable of outdoor laid, the environmental suitability of inside cable requires not high, but because of its laying installation limited space, thereby require very high to the bending property of inside cable.With regard to optical fiber, for adapting to indoor service condition, specially develop the G.657 optical fiber of loss bend-insensitive in recent years, it can still can keep low-loss under very little bending radius.And the design of various inside cables is also had it invariably in mind good bending property must be arranged.But take a broad view of in the various inside cable structures of present existence,, no matter be nonmetal all kinds of FRP, or be the metal steel wire, all influenced the bending property of optical cable as long as the anti-element of opening of rigidity is arranged.
The utility model content
The technical problems to be solved in the utility model is: in order to overcome above-mentioned technical matters, a kind of flexible optical cable is provided, it has good bending property and fire resistance, is fit to be applied to wait the especially little occasion of various requirement bending radius in succession in indoor, machine room, the equipment.
The technical scheme that its technical matters that solves the utility model adopts is: a kind of flexible optical cable, have optical fiber and oversheath, also has the spirality metal flexible pipe that turns to by stainless steel sheet|, penetrate at least two optical fiber in the metal hose, and the outer hard-pressed bale of optical fiber has cushion, metal hose is outside equipped with the braid that is formed by steel wire or organdy braiding, and braid coats oversheath outward.
Further, the described number of fibers that penetrates in the metal hose is 2～8, and fibre diameter is 0.9mm.
Described oversheath is to be made by tygon or PVC or low-smoke halide-free fireproof composite polyolefine material, therefore has good flame retardancy, is more suitable for being installed on indoor.
The beneficial effects of the utility model are; This flexible optical cable is without any the anti-element of opening of longitudinal stiffness, and metal hose not only has good bending property by the moulding of stainless steel sheet| helically coiling, and provides the favorable mechanical protective effect to optical fiber, has particularly strengthened the compressive property of optical cable; Optical cable adopts resistant to bending G.657 optical cable, and whole optical cable presents flexible characteristic; Metal hose, steel wire or organdy braid and oversheath all have good flame retardancy; Be fit to be applied to connect in indoor, machine room, the equipment etc. and require the especially little occasion of bending radius.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a structural representation of the present utility model.
Wherein: 1. optical fiber, 2. cushion, 3. metal hose, 4. braid, 5. oversheath.
Embodiment
As shown in Figure 1, a kind of flexible optical cable, have optical fiber 1 and oversheath 5, also has the spirality metal flexible pipe 3 that turns to by stainless steel sheet|, penetrate at least two optical fiber 1 in the metal hose 3, and optical fiber 1 outer hard-pressed bale has cushion 2, and metal hose 3 is outside equipped with the braid 4 that is formed by steel wire or organdy braiding, the braid 4 outer oversheaths 5 that coat.
G.657 optical fiber 1 adopt optical fiber to make, and G.657 optical fiber is a kind of optical fiber of loss bend-insensitive, can still keep low-loss under very little bending radius.Optical fiber 1 number that penetrates in the metal hose 3 can be 2～8, and optical fiber 1 diameter is 0.9mm, and this optical fiber 1 can be directly equipped mutually with the joints of optical fibre.Cushion 2 can be made by materials such as elasticity PVC, vibrin or fire retardant polyolefins.Optical fiber 1 is placed in the metal hose 3, is subjected to the favorable mechanical protection, particularly resistance to compression protection.Braid 4 can be formed by the braiding of zinc plated mild carbon steel silk, also can adopt nonmetallic organdy to work out.Organization level 4 as the anti-element of opening, carries out on high-speed knitter in this cable configuration usually.Oversheath 5 is made by tygon or PVC or low-smoke halide-free fireproof composite polyolefine material, therefore has good flame retardancy, is more suitable for being installed on indoor.
The methods that optical fiber 1 penetrates in the metal hose 3 have two classes: the one, according to the different mining of optical fiber 1 core number, metal hose 3 internal diameters and length with methods such as vibratory drilling method, plunging, vacuum suctions; The 2nd, the stainless steel sheet| corrugated hose outside hard-pressed bale has the optical fiber 1 of cushion 2 directly coiling carry out.
Claims (3)
1. flexible optical cable, have optical fiber (1) and oversheath (5), it is characterized in that: also have the spirality metal flexible pipe (3) that turns to by stainless steel sheet|, penetrate at least two optical fiber (1) in the metal hose (3), and the outer hard-pressed bale of optical fiber (1) has cushion (2), metal hose (3) is outside equipped with the braid (4) that is formed by steel wire or organdy braiding, the outer oversheath (5) that coats of braid (4).
2. flexible optical cable according to claim 1 is characterized in that: described optical fiber (1) number that penetrates in the metal hose (3) is 2～8, and optical fiber (1) diameter is 0.9mm.
3. flexible optical cable according to claim 1 is characterized in that: described oversheath (5) is to be made by tygon or PVC or low-smoke halide-free fireproof composite polyolefine material.
