Abstract
The utility model relates to a communication optical fiber, especially to a rat prevention fiber, characterized in that a protection layer is arranged on the outside of a water blocking layer, a reinforcement unit is uniformly arranged between the protection layer and a protection sleeve, the protection layer is winded on a layer metal strip winded outside the water blocking layer. The metal strip is a non-stainless steel strip, and the number of intertwined steel wires made reinforcement units is larger than 2 strips. The rat prevention fiber implemented by the scheme additionally arranges a rodent prevention metal made prevention layer and a reinforcement unit on the basis of the original fiber structure, the metal made protection layer and a plurality of reinforcement units made of intertwined steel wires provide better rodent prevention ability, mechanical performance and corrosion resistance, which effectively guarantees unblocked fiber communication. The structure of the utility model is reasonable and convenient, and a certain practical significance and application area are provided.
Description
Technical field
The utility model relates to communications optical cable, especially a kind of anti-plague of rats optical cable.
Background technology
The structure of existing optical cable is to be ointment by optical fiber mostly, the core pipe, water blocking layer, strengthening unit and sheath forms, optical fiber and ointment place in the core pipe, be provided with water blocking layer outside the core pipe, water blocking layer appearance symmetria bilateralis is provided with metal reinforcement unit, sheath is to be wrapped in the core pipe, water blocking layer, strengthen the cable skin outside the unit, and common sheath uses organic material to make more, this material is difficult to resist rodentine cracking between the teeth such as various muroids and stings, in case the sheath of optical cable cracked between the teeth sting impaired, gently then optical cable inside can be corroded at short notice and be had the hidden danger that opens circuit, heavy then optical cable is promptly bitten broken, causes communication disruption.Therefore, the structure of existing optical cable is difficult to stop cracking between the teeth of muroid animal to sting infringement.
The utility model content
The purpose of this utility model, be propose a kind of have prevent that mouse from cracking the anti-plague of rats optical cable of stinging infringement between the teeth.For achieving the above object, adopt following technical scheme: a kind of anti-plague of rats optical cable, comprise optical fiber and ointment, core pipe, water blocking layer, reinforcement unit, sheath, it is characterized in that being provided with outside the water blocking layer protective layer, be laid with the reinforcement unit between protective layer and the sheath uniformly; Protective layer is the layer of metal band that is wound in outside the water blocking layer, and metal tape is a stainless steel band; Strengthening the unit is that stranded steel wire is made, and the number of the reinforcement unit that stranded steel wire is made is more than 2.
Press the anti-plague of rats optical cable that this programme is implemented, owing on the basis of former cable configuration, set up and had anti-metal protective layer and many stranded metal reinforcement unit stung of cracking between the teeth, many the reinforcement unit that metal protective layer and stranded steel wire are made have effectively guaranteed the unimpeded of fiber optic cable communications for optical cable provides good anti-stinging property, mechanical property and the corrosion resistance of cracking between the teeth.The utility model is rational in infrastructure simple and direct, has certain Practical significance and range of application.
Description of drawings
Fig. 1 is the section structure synoptic diagram of a kind of embodiment of the utility model;
Fig. 2 is the section structure synoptic diagram of a kind of embodiment of the utility model.
Embodiment
Be described in further detail with regard to two kinds of embodiment respectively in conjunction with the accompanying drawings.A kind of by optical fiber 6 and ointment 7, core pipe 5, waterstop 4, strengthen unit 2 and constitute by the sheath 1 of high density PE material system, sting in order to prevent cracking between the teeth of muroid animal, twine the protective layer 3 of one deck stainless steel band system outside waterstop 4 in the mode of spiral, this protective layer 3 can prevent effectively that muroid stings cracking between the teeth of its internal optical fiber.For making full use of the structure function of strengthening the unit, increasing the quantity of strengthening the unit helps stoping cracking between the teeth of muroid to be stung, for this reason, the bar number that present embodiment will be strengthened the unit is made as 7, each is strengthened unit and is all made by stranded steel wire, 7 strengthen the unit routinely technology be laid in protective layer 3 uniformly---the periphery of stainless steel band, and be wound in protective layer 3 outsides in a spiral manner, adopt the reinforcement unit of this programme design, have the effect that stops muroid that cracking between the teeth of inside of optical fibre stung.The protective layer of stainless steel band system not only has protection against rodents and cracks the function of stinging between the teeth, and possesses good corrosion-resisting function.So the optical cable of structure protection against rodents is cracked between the teeth sting, corrosion-resistant, water-proof function three is combined into one, and is of the present utility model rational in infrastructure and simple and direct, has certain market prospect.
