Abstract
The utility model provides a micro beam tube type optical cable, comprising a hollow layer, an optical fiber layer and an outer protective layer which are sequentially arranged from inside to outside. The outer protective layer comprises a sheath and a reinforcing part, and the sheath holds the reinforcing part. The microbeam tube type optical cable has the advantages that the microbeam tube type optical cable adopts a three-layer structure, and the outer protective layer holds the reinforcing part, so that the microbeam tube type optical cable is simple in structure, and simultaneously is applicable to indoor environments with small space and small curvature radius. Simultaneously, optical fibers, microbeam tubes and reinforcing filling materials are arranged in the optical fiber layer, and a center reinforcing part is arranged in the hollow layer, thereby increasing integration, environmental protection property and safety of the optical cable. In addition, the microbeam tube type optical cable is portable.

In recent years, its developing trend of inside cable both domestic and external is in environmental protection, safety, highly integrated and superior adaptive capacity to environment.In actual applications, particularly very limited in order to the space of arranging optical cable in skyscraper, (2.0mm～3.0mm) is as the basic composition unit of inside cable with 900 μ m tight tube fibers or single fiber cable for original inside cable.
The technical matters that this structure inside cable exists is:
The first, the inside cable volume is big, takies wiring space, so increase maintenance difficulties and maintenance cost;
The second, the optical cable baring operation is many, and the engineering time is long, has increased difficulty of construction and executive cost.
The utility model content
In order to solve existing technical matters, the utility model provides a kind of minibundle cable, and it is simple for structure, is applicable to the indoor environment of arranging little space and small curvature radius.
The utility model solves existing technical matters, and a kind of minibundle cable is provided, and it comprises hollow layer, optical fiber layer and the outer jacket of order setting from inside to outside, and described outer jacket is an oversheath and interior ccontaining reinforcement thereof.
The utility model further improves as follows.
Described oversheath is the oversheath of a low-smoke non-halogen flame-retardant.
Described optical fiber layer is that microbeam pipe, correspondence are placed in the optical fiber in the microbeam pipe and are filled in reinforcement filling material between microbeam pipe and the outer jacket, and described microbeam pipe is a plurality of and distributes in the form of a ring.
Described reinforcement filling material is an aromatic polyamide fibre.
Described optical fiber is single.
The radical of described optical fiber is 2～12.
Described optical cable comprises central reinforce member, and described central reinforce member is placed in described hollow layer.
Described central reinforce member is a FRP pipe.
Described microbeam pipe is a plurality of.
Described optical cable is a centrosymmetric structure.
Compared to prior art, the beneficial effects of the utility model are: adopt ccontaining reinforcement in three-layer structure, the outer jacket, when making the utility model cable configuration succinct, be applicable to the indoor environment of arranging little space and small curvature radius.Simultaneously, optical fibre, microbeam pipe and reinforcement filling material in the optical fiber layer, ccontaining central reinforce member in the hollow layer, integrated level, environmental-protecting performance and the security performance of raising optical cable.Optical cable of the present utility model uses portable.

Embodiment
Below in conjunction with description of drawings and embodiment the utility model is further specified.
Extremely shown in Figure 9 as Fig. 1, a kind of minibundle cable, it comprises hollow layer, optical fiber layer and the outer jacket 1 of order setting from inside to outside, outer jacket 1 is an oversheath and interior ccontaining reinforcement 6 thereof, this reinforcement 6 has the material of equal enhancing effectiveness for fibre-reinforced plastics or other, for example: the aramid fiber resin composite materials.
Oversheath is the oversheath of a low-smoke non-halogen flame-retardant, or other is known and knows the oversheath with equal flame-proof environmental protection effectiveness material.
Optical fiber layer be microbeam pipe 4, correspondence be placed in the optical fiber 2 in the microbeam pipe 4 and be filled in microbeam pipe 4 and outer jacket 1 between reinforcement filling material 5, microbeam pipe 4 is a plurality of and distributes in the form of a ring, this optical fiber 2 is colored optical fiber or is lock coloured light fibre that colored optical fiber or lock coloured light fibre comprise all band single-mode fiber, the anti-curved single-mode fiber of all band, 62.5/125 μ m multimode optical fiber, 50/125 μ m multimode optical fiber and 50/125 μ m laser and optimize multimode optical fiber.Strengthening filling material 5 be aromatic polyamide fibre, or other is known and knows to have the material that effectiveness is protected in equal enhancing.Optical fiber 2 is single, also can be many, and the range of choice of its optical fiber 2 radicals is 2～12 in the time of many.
When the radical of optical fiber 2 more than 1 the time, this optical cable comprises central reinforce member 3, this central reinforce member 3 is that a FPR manages it and is placed in hollow layer.
Microbeam pipe 4 of the present utility model is a plurality of, evenly distributes.The utility model optical cable is a centrosymmetric structure, and promptly each microbeam pipe 4 is compared central reinforce member 3 distribution that is centrosymmetric.
