Abstract

The utility model relates to an indoor optical cable, comprising an optical fiber, reinforcing members arranged in parallel at two sides of the optical fiber, and a cable core protecting sheath for covering the optical fiber and the reinforcing members; an external reinforcing and protecting layer is covered outside the cable core protecting sheath. Compared with the prior art, the external reinforcing and protecting layer with smooth surface, small friction coefficient and high mechanical strength is additionally arranged; the utility model solves the problems that the protecting sheath of the indoor optical cable in the prior art has low mechanical strength and large friction coefficient and the actual wiring capability is not utilized sufficiently; and the construction laying difficulty is reduced.

Description

A kind of optical cable of registering one's residence

Technical field

The utility model relates to a kind of optical cable of registering one's residence.

Background technology

Along with the continuous growth of Fiber to the home (FTTH) continuous advancement in technology and bandwidth demand, how optical fiber being incorporated into user side from the Optical Distribution Point of Access Network has become the hot technology that people pay close attention to.Usually we are called leading in cable with this section optical cable.

Granted publication number comprises optical fiber, reinforcement and cable jacket for CN201765360U Granted publication day is the structure that the flexible covered wire cable of 2011.03.16 discloses a kind of optical cable, and optical fiber is between reinforcement, and cable jacket coats reinforcement and optical fiber.Consider the demand of environmental protection, cable jacket generally adopts low-smoke halogen-free polyolefin at present, this material is owing to filled a large amount of inorganic combustion inhibitors for satisfying fire resistance, so the physical strength of material is low, and breaking elongation is little, jacket surface is coarse, friction factor is big, therefore requires to adopt initiatively unwrapping wire in construction is laid, simultaneously because friction factor is big, physical strength is hanged down conduit resource same when connecting up, and the practical wiring capacity can't make full use of.

Summary of the invention

The purpose of this utility model is to provide a kind of optical cable of registering one's residence, to solve the problem that cable machinery intensity is low, friction factor big and the practical wiring capacity can't make full use of of registering one's residence in the prior art.

In order to address the above problem, a kind of optical cable of registering one's residence of the utility model comprises optical fiber, the reinforcement that be arranged in parallel in the optical fiber both sides and the cable core sheath that wraps up optical fiber and reinforcement, also is enclosed with the enhancing outer jacket outside described cable core sheath.

The profile of described enhancing outer jacket is " 8 " font.

Described optical fiber is an optical fiber or two or four optical fiber be arrangeding in parallel.

Described reinforcement is made by fibre-reinforced plastics or steel wire.

Described inner sheath is the low-smoke non-halogen flame-retardant inner sheath.

Compare in the utility model and the prior art, increased one deck smooth in appearance, friction factor is little, the enhancing outer jacket that physical strength is high, solved the problem that cable machinery intensity is low, friction factor big and the practical wiring capacity can't make full use of of registering one's residence in the prior art, reduced construction and laid difficulty.

Fig. 1 is the structural representation of the utility model embodiment.

Embodiment

Below in conjunction with accompanying drawing the utility model embodiment is described in detail:

The register one's residence embodiment of optical cable of a reinforced non-metallic stiffener low-smoke halogen-free flame-retardant sheath of the present utility model, as shown in Figure 1, comprise an optical fiber 1, the cable core sheath 3 of the reinforcement 2 that be arranged in parallel in these optical fiber 1 both sides and parcel optical fiber and reinforcement, described optical fiber 1 is for meeting the G.657.A2 optical fiber of standard, described reinforcement 2 is by fibre-reinforced plastics, particularly fiberglass reinforcement in the fibre-reinforced plastics or aramid fiber fortifying fibre are made, perhaps make by steel wire, feasible register one's residence optical cable softness and good bending property, described cable core sheath 3 has the low bright bittern-free flame-proof material that meets environmental protection RoHS standard to make, safety is fire-retardant, and when fire, do not produce toxic gas, the smog transparency reaches more than 50%, in addition, in the physical dimension in these cable core sheath 3 cross sections, length is 〉=2.0mm, wide is 1.6mm, and this physical dimension can guarantee the satisfied needs of processing once more of the enough physical strengths of subelement user; Outside described cable core sheath 3, also be enclosed with and strengthen outer jacket 4, this strengthens outer jacket by nylon, perhaps high density polyethylene, perhaps polyurethane, perhaps other special plastics are made, this profile that strengthens outer jacket is " 8 " font structure, its contour structure size meets the regulation of table 2 among the YD/T 1997-2009 " Access Network butterfly leading in cable ", can with existing termination box, accessory such as optic panel and quick connection assembly product compatibility, comprehensive oxygen index 〉=30 of the described optical cable of registering one's residence, this optical cable of registering one's residence meet the regulation of every index among YD/T 1954-2009 " Access Network bending loss insensitive single-mode fiber characteristic " and the YD/T 1997-2009 " Access Network butterfly leading in cable ".

In other embodiments, the optical fiber of the described optical cable of registering one's residence can also be two or four optical fiber that be arranged in parallel.
