Abstract
Disclosed in the utility model is an anti-rat biting flat optical fiber ribbon feed line cable that comprises an outer sheath made of a nylon material. An inner protection layer is arranged in the outer sheath; a row of a plurality of optical fiber ribbons that are arranged in parallel is arranged in the inner protection layer; and two reinforced elements made of composite plastics with fiber enhanced are arranged in the inner protection layer. According to the utility model, the provided cable with the simple structure can be used conveniently. Under the circumstances that the cable meets an anti-rat biting performance requirement, the external diameter of the cable can be substantially reduced and the utilization rate of the feed line segment pipeline can be improved. Meanwhile, a long-distance access requirement is met and a support is provided for optical network popularization.
Description
Technical field
The utility model relates to a kind of optical cable, particularly a kind of flat mouse bite preventing fibre ribbon feeder line optical cable.
Background technology
The light unit of existing conventional feeder line optical cable the inside generally all is to adopt loose nested structure, adopt loose nested structure can make that the feeder line cable outer diameter is bigger than normal, flatten little, and because the feeder line optical cable uses outdoor more, so destructive can increase greatly of present stage damaged by rats, just greatly reduce the serviceable life of this routine feeder line optical cable, and application is not strong.
The utility model content
At the deficiency that exists on the prior art, it is a kind of simple in structure that the utility model provides, easy to use, and reach under the anti-performance requirement of protection against rodents at optical cable, reduced cable outer diameter greatly, improved the utilization factor of feeder line section pipeline, also realized that long distance inserts requirement simultaneously, popularizing for optical-fiber network provides the flat mouse bite preventing fibre ribbon feeder line optical cable of supporting.
To achieve these goals, the utility model is to realize by the following technical solutions:
A kind of flat mouse bite preventing fibre ribbon feeder line optical cable, comprise the oversheath of being made by nylon material, be provided with sheath in the described oversheath, be provided with some fibre ribbons that are arranged in parallel of a row in the sheath, be provided with two reinforcements of being made by fibre-reinforced plastics in the sheath.
Further, described fibre ribbon is arranged between two reinforcements.
Further, the described some fibre ribbons that are arranged in parallel are coated in the water blocking yarn.
Further, two described reinforcement is arranged in parallel.
Adopt the flat mouse bite preventing fibre ribbon feeder line optical cable of technique scheme, owing to be provided with sheath in the described oversheath, be provided with some fibre ribbons that are arranged in parallel of a row in the sheath, be provided with two reinforcements of being made by fibre-reinforced plastics in the sheath, so exploitation by new construction, be applicable to that residential quarter machine room to optical cable fiber-dividing box section uses, optical cable has the termite-resistant rodent-resistant function, the place is laid with conduit resource, cable outer diameter is little, in light weight, the density of optic fibre height, capacity is big supporting with outdoor coupling box, uses novel access optical cable then, can realize that long distance is linked into every household.
Description of drawings
Describe the utility model in detail below in conjunction with the drawings and specific embodiments;
Fig. 1 is the structural representation of the flat mouse bite preventing fibre ribbon of the utility model feeder line optical cable.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with embodiment, further set forth the utility model.
As shown in Figure 1, a kind of flat mouse bite preventing fibre ribbon feeder line optical cable, comprise the oversheath of being made by nylon material 5, be provided with sheath 4 in the oversheath 5, be provided with some fibre ribbons that are arranged in parallel 2 of a row in the sheath 4, be provided with two reinforcements of being made by fibre-reinforced plastics 3 in the sheath 4, fibre ribbon 2 is arranged between two reinforcements 3, two reinforcement 3 is arranged in parallel, and the some fibre ribbons that are arranged in parallel 2 are coated in the water blocking yarn 1.
The flat mouse bite preventing fibre ribbon of the utility model feeder line optical cable, for residential quarter machine room to optical cable fiber-dividing box uses, this optical cable extrudes one deck sheath after adding two parallel reinforcements by a fibre ribbon, extrudes one deck nylon sheath wire stranding outward again.Guarantee that reinforcement centre distance meets the requirements, and realizes the use with mating connector.When solving the mouse bite preventing problem, must guarantee that also cable outer diameter remains on more among a small circle.Adopt the direct sheath of fibre ribbon, guarantee that optical cable still can guarantee less external diameter and lighter optical cable weight under the situation with higher density of optic fibre and larger capacity.Direct sheath behind the employing fibre ribbon both sides placement reinforcement so mould must consider when designing that the pull-tube type mould is pushed in employing outside the centre distance that guarantees reinforcement meets the requirements, is controlled cable outer diameter, wall thickness etc. and is met.When guaranteeing the optical cable cost, also need have the mouse bite preventing function, so optical cable increases the nylon sheath wire of one deck thin-walled outside behind the PE sheath.
The flat mouse bite preventing fibre ribbon of the utility model feeder line optical cable, adopt and to pack one deck compound that blocks water around the fibre ribbon, and both sides with two equalitys as reinforcement after, directly adopt the pull-tube type mould to extrude one deck sheath and become cable core, outside cable core, extrude one deck nylon sheath wire stranding again; Has good protection against rodents ant function.External diameter is little, in light weight.Adopt flat structure that more superior anti-collapse performance is arranged.Can with the supporting use of outdoor coupling box.Can utilize existing conduit resource to lay.
More than show and described ultimate principle of the present utility model and principal character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and the instructions just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
