Abstract
The utility model provides a kind of large core number and to fall apart fine formula central tube type optical cable, comprise overcoat and at least two embedded optical cables, embedded optical cable described in described outer sheath covers, described embedded optical cable comprises the first sleeve pipe and at least two optical fiber, and described first sleeve pipe wraps up described optical fiber.The beneficial effects of the utility model are: by arranging many embedded optical cables, improve Cable Core Number, reduce costs, also reduce taking conduit resource.
Description
Technical field
The utility model relates to optics, and the one large core number particularly related in optics falls apart fine formula central tube type optical cable.
Background technology
Along with widespread use and the high speed development of optical fiber communication, the demand of metropolitan area network communications increases day by day, and cause the existing conduit resource growing tension in city, executive cost is also comparatively high.
Summary of the invention
In order to solve the problems of the prior art, the utility model provide a kind of cost low, take the few large core number of conduit resource and to fall apart fine formula central tube type optical cable.
The utility model provides a kind of large core number and to fall apart fine formula central tube type optical cable, comprise overcoat and at least two embedded optical cables, embedded optical cable described in described outer sheath covers, described embedded optical cable comprises the first sleeve pipe and at least two optical fiber, and described first sleeve pipe wraps up described optical fiber.
As further improvement of the utility model, between described first sleeve pipe, optical fiber, be filled with the first fine ointment.
As further improvement of the utility model, between described overcoat, embedded optical cable, be filled with the second fine ointment.
As further improvement of the utility model, described overcoat comprises the second sleeve pipe and oversheath, described second sleeve pipe of described oversheath parcel, the described embedded optical cable of described second sleeve pipe parcel.
As further improvement of the utility model, between described second sleeve pipe, oversheath, be provided with waterstop or ointment.
As further improvement of the utility model, described oversheath is provided with the reinforcement arranged along its length.
As further improvement of the utility model, described reinforcement has two and along 180 degree, the circumferential interval setting of described oversheath.
As further improvement of the utility model, described reinforcement is symmetrical arranged along described oversheath.
As further improvement of the utility model, described reinforcement is metal reinforcement.
As further improvement of the utility model, described reinforcement is non-metal reinforcement member.
As further improvement of the utility model, described embedded optical cable has two at least.
As further improvement of the utility model, described embedded optical cable has four.
The beneficial effects of the utility model are: by such scheme, by arranging many embedded optical cables, improving Cable Core Number, reducing costs, also reduce taking conduit resource.
Accompanying drawing explanation
Fig. 1 is that a kind of large core number of the utility model falls apart fine formula central tube type optical cable.
Embodiment
To illustrate below in conjunction with accompanying drawing and embodiment further illustrates the utility model.
Drawing reference numeral in Fig. 1 is: optical fiber 1; First fine ointment 2; First sleeve pipe 3; Second fine ointment 4; Second sleeve pipe 5; Waterstop 6; Oversheath 7; Reinforcement 8.
