Abstract
The utility model discloses a FTTH is with preventing cicada evil leading in cable, including reinforcement, optic fibre, butterfly sheath and outer protection jacket, the optic fibre setting on butterfly sheath central line, the reinforcement setting at butterfly sheath both wings, the outer protection jacket cladding peripheral at the butterfly sheath. This novel leading in cable plays the guard action to optical cable inside optic fibre, has improved the life of smooth borer.
Description
[technical field]
The utility model relates to optical cable technology field, relates to the anti-cicada evil leading in cable of a kind of FTTH.
[background technology]
The Access Network stage between fiber to the home (FibertotheHome, FTTH) refers to from backbone network to community user all uses optical fiber, realizes voice, a kind of access way of data and all kinds of intellectualizing system function.Along with the fast development of optical fiber cable, communication line suffers the damage of wildlife again and again, comprise rodent (squirrel, mouse), the infringement of insects (cicada, ant, cockroach etc.) and birds (woodpecker, crow etc.), and they to the degree of damage of optical cable in ascendant trend year by year.Wherein, the impact that the leading in cable used in FTTH is subject to cicada evil is larger.Cicada can utilize its sharp-pointed mouthpart and tube for laying eggs to thrust optical cable, causes the damage of cable inner fiber, affects the transmission performance of optical fiber.
[utility model content]
In order to solve the transmission performance of cicada to the destroying infection optical fiber of optical cable butterfly sheath, the utility model provides the anti-cicada evil leading in cable of a kind of FTTH, and this novel leading in cable plays the protective effect to optical cable internal optical fiber.
The purpose of this utility model is achieved through the following technical solutions:
The anti-cicada evil leading in cable of a kind of FTTH; comprise reinforcement, optical fiber, butterfly sheath and outer jointing jacket; described optical fiber is arranged on butterfly sheath center line, and described reinforcement is arranged on butterfly sheath both wings, and it is peripheral that described outer jointing jacket is coated on butterfly sheath.
Form V-type through hole between V-type groove between the outside both wings of described butterfly sheath and outer jointing jacket, be provided with in V-type through hole and tear rope.
Described outer jointing jacket is tearing rope and butterfly sheath outside by nylon material extrusion moulding.
Described outer jointing jacket is rectangular configuration.
Described butterfly sheath is low-smoke halogen-free flame-retardant sheath.
The thickness of described outer jointing jacket is 0.3mm.
Relative to prior art, the utility model has following beneficial effect:
A kind of FTTH of the utility model optical fiber both sides of anti-cicada evil leading in cable are distributed with two stiffeners, add tension and the compressive property of optical cable.And the V-type groove in butterfly structure facilitates being separated of optical cable butterfly sheath and optical fiber.The outer jointing jacket that optical cable outside extrudes; because its smooth surface is wear-resisting and shrinkability good; the mouthpart that cicada is sharp-pointed and tube for laying eggs not easily thrust at butterfly jacket surface, if thrust, can be shunk at short notice, play the protective effect to optical cable internal optical fiber by the hole stung.
Further, in the V-type groove of butterfly structure, add and tear rope, it is easier by outer jointing jacket strip off that rope is torn in utilization, is separated by optical cable butterfly sheath subsequently by optical cable V-type groove with optical fiber.
Further, the nylon sheath wire extruding one deck rectangle in the outside of butterfly optical cable carries out coated, and this nylon material smooth surface is wear-resisting and have certain rebound resilience.Prevent cicada evil, play the protective effect to optical cable internal optical fiber.
[accompanying drawing explanation]
The novel leading in cable sectional view of Fig. 1 anti-cicada evil;
Fig. 2 tears rope and outer for nylon butterfly sheath is torn schematic diagram.
Wherein, 1. reinforcement; 2. optical fiber; 3. tear rope; 4.V type groove; 5. butterfly sheath; 6. outer jointing jacket.
[embodiment]
Be described further the utility model below in conjunction with the drawings and specific embodiments, the utility model is not limited to following examples:
A kind of FTTH with anti-cicada evil leading in cable by metal/non-metal reinforcement 1, optical fiber 2, tear rope 3, V-type groove 4, low-smoke non-halogen flame-retardant butterfly sheath 5 and nylon outer jointing jacket 6 and form.Optical fiber 2 is protected in the middle of optical cable, stiffener 1 is distributed in the both sides of optical fiber, at the butterfly sheath 5 that the outside extrusion molding of optical fiber 2 and stiffener 1 has halogen-free low-smoke flame retardant material to make, and have symmetrical V-type groove 4 at the horizontal level of optical fiber 2, peel off although this V-type groove 4 structure makes optical cable butterfly sheath and optical fiber is convenient, but due to the geometric properties of V-type groove 4, cicada is made to have good center of effort to thrust in optical cable by tube for laying eggs, and this V-type groove 4 position and optical fiber horizontal, be easy to after tube for laying eggs thrusts damage optical fiber, destroy the transmission performance of optical fiber, fibercuts may be caused time serious.Therefore outside low-smoke non-halogen flame-retardant butterfly sheath 5; extrude one deck and extrude out one deck outer jointing jacket 6; carry out coated; outer jointing jacket 6 smooth surface of this nylon material is wear-resisting and have certain rebound resilience; the tube for laying eggs of cicada is difficult to find center of effort at this butterfly jacket surface, thus protects the optical fiber in cable.
Bring certain difficulty also to the stripping of optical fiber with the outer jointing jacket 6 of Smooth, therefore add in V-type groove 4 and tear rope 3, just can utilize at the end of optical cable that tearing restricts peels off the outer jointing jacket 6 of optical cable, as shown in Figure 2.And then by V-type groove 4, low-smoke non-halogen flame-retardant butterfly sheath 5 and optical fiber 2 are peeled off.
The above; it is only a kind of embodiment of the utility model; above-described embodiment not does any restriction to the utility model; every scope given by technical solutions of the utility model and to any simple modification made for any of the above embodiments, change and equivalent structure change, all still belongs to the protection domain of technical solutions of the utility model.
