Abstract

The utility model discloses a waterproof-type rateproof radio-frequency remote optical cable, and the optical cable comprises an outer protection layer which wraps a water-resistant fiberglass yarn. The water-resistant fiberglass yarn wraps a plurality of nylon tightly-wrapping layers, and the interior of each nylon tightly-wrapping layer is provided with an optical fiber. According to the utility model, the water-resistant fiberglass yarn is employed for improving the performances of the optical fiber, such as resistance to rate biting, and the like. The nylon tightly-wrapping layers are employed, thereby enabling attenuation to be higher in stability and better in performance of resistance to rate biting.

Description

A kind of waterproofing type protection against rodents remote radio optical cable

Technical field

The utility model relates to a kind of optical cable, particularly a kind of waterproofing type protection against rodents remote radio optical cable.

Background technology

Remote radio optical cable is applicable to the introducing of communication base station, and the principal feature of this optical cable is high-intensity nonmetal reinforcement, guarantees that Optical Fiber Transmission performance is steady in a long-term; External diameter is little, lightweight, fire-retardant, easily peel off, and has high flexibility; Often with light unit, can use the direct termination of standard connector; Adopt LSZH fire proofing, reach the performance requirement of fire-retardant and environmental protection; Constructability and maintenance.Along with the great development that FTTx builds in recent years, optical fiber is progressively unrestrained near to user side, and FTTx construction not only requires networking flexibility convenient, also needs with low cost.The remote radio optical fiber cables cable structure of application is large in the market, and external diameter is large, and weight is large, and the load that is subject to external environment weather and icing also can increase, corresponding, and the aramid fiber of use is also many, and price will be higher like this.The general cable core of the dual-purpose remote radio optical cable of traditional waterproofing type indoor and outdoor adopts water resistance aramid fiber yarn reinforcement structure and does not possess mouse bite preventing function, as shown in Figure 1, aramid yarn reinforcement is widely used in inside cable, aramid yarn is a kind of synthon, there is superhigh intensity, high-modulus and high temperature resistant, acid-fast alkali-proof, the premium properties such as lightweight, but aramid fiber in use cost is high, waterproofing type aramid yarn especially.

Utility model content

For the deficiency existing in prior art, the utility model provides a kind of employing waterproofing type glass fiber yarn, has increased many performances such as mouse bite preventing of optical cable; Adopt nylon tightly to overlap, decay has better stability, can also have the waterproofing type protection against rodents remote radio optical cable of good mouse bite preventing performance simultaneously.

To achieve these goals, the utility model is to realize by the following technical solutions:

A waterproofing type protection against rodents remote radio optical cable, comprises outer jacket, in described outer jacket, is coated with the glass fibre yarn that blocks water, and is coated with some nylon hard-pressed bale layers in the glass fibre yarn that blocks water, and in each nylon hard-pressed bale layer, is provided with optical fiber.

Further, the outside surface of described optical fiber is provided with protective seam.

Further, described outer jacket is high-density polyethylene layer.

Adopt the waterproofing type protection against rodents remote radio optical cable of technique scheme, owing to being coated with the glass fibre yarn that blocks water in described outer jacket, block water in glass fibre yarn and be coated with some nylon hard-pressed bale layers, in each nylon hard-pressed bale layer, be provided with optical fiber, so reinforcement adopts waterproofing type glass fiber yarn, do not affecting on the mechanical property of optical cable and the basis of environmental performance, increasing many performances such as mouse bite preventing of optical cable.Fiber optic protection layer adopts nylon tightly to overlap, and the tight cover of nylon material is subject to ectocine power little, and decay has better stability, can also have good mouse bite preventing performance simultaneously.

Accompanying drawing explanation

Below in conjunction with the drawings and specific embodiments, describe the utility model in detail;

Fig. 1 is the structural representation of the utility model waterproofing type protection against rodents remote radio optical cable.

Embodiment

For technological means, creation characteristic that the utility model is realized, reach object 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 waterproofing type protection against rodents remote radio optical cable; comprise outer jacket 4; in outer jacket 4, be coated with the glass fibre yarn 3 that blocks water; block water in glass fibre yarn 3 and be coated with some nylon hard-pressed bale layers 2, in each nylon hard-pressed bale layer 2, be provided with optical fiber 1, the quantity of nylon hard-pressed bale layer 2 can for 2,3,4 and more than; the outside surface of optical fiber 1 is provided with protective seam, and outer jacket 4 is high-density polyethylene layer.

The utility model waterproofing type protection against rodents remote radio optical cable, reinforcement adopts waterproofing type glass fiber yarn, is not affecting on the mechanical property of optical cable and the basis of environmental performance, has increased many performances such as mouse bite preventing of optical cable.Fiber optic protection layer adopts nylon tightly to overlap, and the tight cover of nylon material is subject to ectocine power little, and decay has better stability, can bear wider thermocycling; Reinforcement adopts waterproofing type glass fiber yarn, and in the situation that with low cost, mechanical property, no less than aramid fiber yarn, can also have good mouse bite preventing performance simultaneously; According to optical cable environment for use, adopt LSZH fire proofing, reach the performance requirement of fire-retardant and environmental protection.Outside single mode or multimode optical fiber, directly coated with the tight cover material of high bond strength, make tight tube fiber, extrude one deck LSZH sheath stranding after tight tube fiber is placed on to nonmetal glass fibre yarn centre.The utility model waterproofing type protection against rodents remote radio optical cable, simple in structure, lightweight, easy construction is quick, has reduced greatly construction period and construction cost, for the development of Access Network provides a kind of brand-new solution; With low cost, there is obvious mouse bite preventing function.

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 in above-described embodiment and instructions, describes just illustrates principle of the present utility model; do not departing under the prerequisite of the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
