Abstract

The utility model provides a tactical optical cable, wherein optical fibers of different types are arranged in chloroprene rubber (CR) tightly-wrapped layers. The outside of a CR filling core is surrounded by six CR tightly-wrapped layers. The outside of the CR tightly-wrapped layers (3) is coated with aramid fibers. A CR outer sheath layer served as an outer sheath layer arranged on the outside of the aramid fibers is high in density and flame-retardant and has two different colors in appearance. The CR filling core is made of flexible and flame-retardant rubber material. The two different colors of the CR outer sheath layer are alternately arranged at intervals. According to the technical scheme of the utility model, due to the adoption of the novel tactical optical cable, the requirements for disseminating different types of information during the military operation can be satisfied. Meanwhile, since the outer sheath layer is designed to look discontinuous in color and is formed through extrusion molding, the camouflage external-protecting effect is realized. Therefore, the novel tactical optical cable is convenient in camouflage and concealment and good in invisible effect.

Description

A kind of novel optical fiber cable for field operation

Technical field

The utility model relates to the optical cable technology field, says that accurately it is a kind of stealthy optical fiber cable for field operation of propagating different information requirements in the military combat that satisfies.

Background technology

The field operations optical fiber cable for field operation is a kind of metal free optical fiber cable that quickly retracting uses repeatedly under the harsh and unforgiving environments that reaches in the open air.It is little, in light weight that optical fiber cable for field operation has the line footpath; Little, the bandwidth of loss; Anti-electromagnetic interference (EMI) is strong, advantages such as anti-eavesdrop, and therefore extremely the military pays close attention to.Traditional optical fiber cable for field operation exposes following deficiency:

1, an optical cable only holds model optical fiber of the same race and can only satisfy a kind of user demand;

2, the protective cover material performance is not enough, exposes for a long time outdoor to be worn easily, to destroy even corrode;

3, single black restrictive coating is found to be destroyed easily.

The utility model mainly solves an optical cable has the different model tight tube fiber to transmit signal with different type, is used the flame-retardant chloroprene rubber of more high-intensity flexibility to run business into particular one again and fills out core, tight sleeve layer, external sheath layer raising optical fiber cable for field operation intensity.Particularly be outer protect to adopt greenly be interrupted look with brown so that optical cable should not by enemy scout naked eyes be detected optical cable position when laying in the open air.

Summary of the invention

Technical problem to be solved in the utility model provides a kind of novel optical fiber cable for field operation of propagated demand when satisfying military combat confidentiality and multiple information of same, it is made up of the fire-retardant more high-intensity neoprene filled core of six roots of sensation different fiber winding by an optical cable, the high strength aramid fiber is done reinforcement in addition again, by the adjusting of oversheath material color, make optical cable in process of deployment, adapt to surrounding environment and reach the stealthy degree of camouflage.It is characterized in that: different classes of optical fiber is in neoprene hard-pressed bale layer, neoprene filled core outside is around 6 neoprene hard-pressed bale layers, neoprene hard-pressed bale layer holds aramid fiber outward, and the aramid fiber outer jacket is the neoprene outer jacket of the high-density flame-proof of two kinds of different colours.Neoprene filled core 1 is taked flexible flame retardant rubber.Two kinds of different colours of neoprene outer jacket 5 are spaced.

The beneficial effects of the utility model are:

1, takes optical fiber combination such as different fiber such as multimode, single mode, dispersion shift, nuclear hardening to become optical cable, can satisfy the difference in functionality needs;

2, use the neoprene sheath and add core and can strengthen optical cable flexibility and pull resistance, increase the optical cable bending fatigue strength;

3, rebound resilience is bigger;

4, flame retardant effect is arranged;

5, the anti-electromagnetic-radiation ability is strong;

6, uvioresistant, anti-strong acid, alkali corrosion;

7, outside surface and field environment are close, are difficult for being investigated by the enemy.

Description of drawings

The present invention is further detailed explanation below in conjunction with the drawings and specific embodiments.

Fig. 1 is the stealthy optical fiber cable for field operation structural drawing of the utility model.

Among the figure, 1. neoprene filled core, 2. optical fiber, 3. neoprene hard-pressed bale layer, 4. aramid fiber, 5 neoprene outer jackets.

Embodiment

Different model optical fiber 2 evenly distributes around neoprene filled core 1 and around aramid fiber 4 is arranged through neoprene hard-pressed bale layer 3 protection back wall in the utility model, and adopts neoprene outer jacket 5 to be protected.

Optical fiber tightly overlaps

Choose multiple model optical fiber according to different demands, tightly overlap.Tight cover can effectively be protected optical fiber, increases the mechanical fiber optic performance.Use the neoprene of different colours as the sleeve pipe material, so that the differentiation that continues during tight overlapping.

Stranding, sheath

Stranded to together with tight sleeve pipe, filled core nature, purpose be element is closed as a whole.Aramid fiber is main reinforcement.The restrictive coating of optical cable is used for protecting cable core, makes cable core avoid the influence of extraneous mechanical effect and environmental baseline.Adopt brown protective cover material main frame extrusion molding during sheath, the green cladding interruption of squeezing does not pack tightly crowded skin, is made into the outer jacket that is similar to camouflage color.The tightly packaged fiber six roots of sensation that use takes different size optical fiber to make according to different needs is twined and the neoprene filled core is directly put stranding, and aramid fiber is evenly directly put all around and taked green and brown butadiene rubber protective cover material sheath at intermittence to make the alternate camouflage painting optical cable of color behind the stranding.

Claims
