Description

Ten-thousand-million multimode optical cable

Technical Field

The utility model relates to an optical cable technical field, concretely relates to ten thousand million multimode optical cables.

Background

With the vigorous development of the national network communication industry, multimedia such as voice, data, images and the like need to be transmitted, and further, an optical cable is required to have larger network capacity and wider bandwidth. The existing optical cable is generally sheathed with a sheath on the outer periphery of a cable core and then is transmitted by the cable core, but the optical cable has low strength, low toughness and low transmission capacity and has certain problems in the process of splicing the optical cable.

SUMMERY OF THE UTILITY MODEL

The utility model aims at the not enough of existence among the above-mentioned background art, provide a simple structure, ten thousand million multimode optical cables that transmission capacity is big.

In order to achieve the above object, the utility model relates to a ten thousand million multimode optical cables has adopted following technical scheme:

the utility model provides a ten thousand million multimode optical cables, includes three piece at least tight cover optic fibre, separate by soft separator between the tight cover optic fibre, the tight cover optic fibre outside is provided with the inner sheath, be provided with filiform aramid fiber between inner sheath and the tight cover optic fibre, all tight cover optic fibre peripheries are provided with the metal armor, be provided with the inner liner between metal armor and the tight cover optic fibre, metal armor periphery is provided with the oversheath. Set up the separator so that can not appear the dislocation when the optical cable is continuous to connect and continue to connect, guarantee the continuous integrality of continuous connecing, and then guarantee data transmission's stability.

The utility model relates to a ten thousand million multimode optical cables's further improvement parts lie in, one side that the inner liner is close to tight set optic fibre is provided with interior concave part, tight set optic fibre blocks spacingly with interior concave part mutually. The arrangement of the concave part realizes the limitation of the tight-buffered optical fiber, and the fixation stability of the tight-buffered optical cable is ensured.

The utility model relates to a ten thousand million multimode optical cable's further improvement parts lie in, tight cover optic fibre is ten thousand million multimode optical fibre.

The utility model relates to a ten thousand million multimode optical cables's further improvement parts lie in, inner sheath, oversheath all adopt low smoke and zero halogen material preparation. The flame-retardant material is used for manufacturing the sheath, so that the flame-retardant safety of the optical cable is ensured.

The utility model relates to a ten thousand million multimode optical cables's further improvement parts lie in, the metal armor with be provided with waterproof grease layer between the inner liner.

Compared with the prior art, the beneficial effects of the utility model are that:

the utility model discloses be equipped with the separator between tight-buffered optical fiber and separate adjacent tight-buffered optical fiber, be convenient for when the optical cable is spliced, can splice between the single tight-buffered optical fiber, guarantee that the optical cable can not appear the condition of dislocation splicing when splicing, guarantee the stability of transmission; meanwhile, at least three tight-sleeved optical fibers are arranged, so that the transmission quantity of data is enhanced.

Drawings

Fig. 1 is a schematic structural view of the present invention;

in the figure: 10 tight-buffered optical fibers, 11 filiform aramid fibers, 12 inner sheaths, 20 separators, 30 metal armor layers, 40 inner liners, 41 concave parts, 50 outer sheaths and 60 waterproof ointment layers.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

As shown in fig. 1, a gigabit multimode optical cable includes at least three tight-buffered optical fibers 10, the tight-buffered optical fibers are separated by a soft separator 20, an inner sheath 12 is disposed outside the tight-buffered optical fibers 10, and a filamentous aramid fiber 11 is disposed between the inner sheath and the tight-buffered optical fibers to enhance the tensile resistance of the optical fibers. All tight-buffered optical fibers 10 are provided with a metal armor layer 30 around the circumference to enhance the overall strength of the cable. An inner liner 40 is arranged between the metal armor layer 30 and the tight-buffered optical fiber 10, and an outer sheath 50 is arranged on the periphery of the metal armor layer.

Further, an inner concave part 41 is arranged on one side, close to the tight-buffered optical fiber, of the inner liner layer 40, and the tight-buffered optical fiber 10 is clamped and limited with the inner concave part 41. The tight-buffered optical fiber is limited and fixed, and the overall stability of the optical cable is further ensured.

Specifically, the tight-buffered optical fiber 10 is a ten-thousand-million multimode optical fiber, and the inner sheath 12 and the outer sheath 50 are both made of low-smoke halogen-free materials.

Further, a waterproof grease layer 60 is disposed between the metal armor layer 30 and the inner liner layer 40. The integral waterproofness of the optical cable is ensured.

It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention.
