Abstract
The invention relates to a distortion-resistance-type butterfly-shape optical cable. The optical cable comprises reinforcement components (1), optical fibers (2) and a sheath (4). A center position of the sheath (4) is provided with the plurality of optical fibers (2). A cross section of the sheath (4) is a butterfly structure. The two reinforcement components (1) are arranged in the sheath (4) and are distributed on two sides of the optical fibers and are symmetrical about the optical fibers. Left and right sides of the optical fibers (2) are provided with two tearing ports (3). The tearing ports (3) are in a trapezoidal shape. A center connection line of the reinforcement components (1) is mutually parallel to a bottom line of the tearing ports (3). The optical fibers (2) are distributed on the two sides of the center connection line of the reinforcement components (1). The reinforcement components (1), the optical fibers (2) and the tearing ports (3) are not contacted with each other. The optical cable of the invention has the advantages that distortion-resistance performance is good; optical cable performance is stable; a service life is long; construction and laying are easy.
Description
Technical field
The present invention relates to a kind of dished optical cable, particularly a kind of twist-resistant type butterfly optical cable.
Background technology
Fast development along with telecommunications industry, people are more and more higher to the demand of bandwidth, the inside and outside numerous and confused mode that adopts the optical fiber access in native land, Fiber To The Building to FTTB(along with photoelectric communication), the FTTO(Fiber-To-The-Office), FTTH(fiber-to-the-home front yard) etc. the development of direction, butterfly optical cable is used in Access Network in a large number.For this reason, People's Republic of China's communications industry has been formulated standard YD/T 1997-2009 " Access Network butterfly leading in cable ".Yet the optical cable of most divides the triangle that is shaped as one jiao of forward optical fiber of breach or subtriangular, and such structure has shortened the optical cable life-span greatly so that optical cable usually is torn in a large amount of deposited workers.
Chinese patent application number: 201010174444.9 disclose a kind of butterfly optical cable with skeleton; it comprises a skeleton that is positioned at the optical cable center at least; one is coated on the outer protective seam of skeleton; two the first reinforcements that lay respectively at the relative both sides of skeleton; one integral coating is lived skeleton; the restrictive coating of the first reinforcement and protective seam; a plurality of skeleton grooves are arranged on the skeleton; be placed with optical fiber or the fibre ribbon of dispersion in the skeleton grooves; on arbitrary xsect; the length of the center of the line process skeleton at the first reinforcement center and the line of reinforcement center trace frame center equates; crossing frame center and with the other both sides of the perpendicular skeleton of the line at the first reinforcement center a pair of tearing port is being arranged, tearing port is shaped as triangle.This structure is when the construction distortion, and the optical cable life-span just naturally separately until optical fiber or fibre ribbon place cause optical cable to be torn, shortens in the tearing port place, affects product quality.
Summary of the invention
The object of the invention is to overcome the shortcoming of prior art, a kind of twist-resistant type butterfly optical cable with good torsional resistance is provided, have more stable properties of optical fiber cable, longer life-span, easier construction and lay.
Purpose of the present invention is achieved through the following technical solutions: a kind of twist-resistant type butterfly optical cable, it comprises stiffener, optical fiber and sheath, the center of sheath is multifiber, the xsect of sheath is butterfly structure, be provided with two stiffeners in the sheath, and stiffener is distributed in the both sides of optical fiber and about the optical fiber symmetry, is provided with two tearing ports on the sheath of the optical fiber left and right sides.
Described tearing port is trapezium structure, and the line of centres of stiffener and the base of tearing port are parallel to each other, and fiber distribution is in the both sides of the line of centres of stiffener, and does not contact mutually between stiffener, optical fiber and the tearing port.
Described optical fiber is G652 type or G655 type or G656 type or G657 type.
Described stiffener is steel wire, GFRP or KFRP.
Described stiffener diameter is 0.4mm～0.6mm.
Described sheath is that PVC or low smoke halogen-free flame-retardant polyolefin are made.
The present invention has the following advantages:
1, tearing port adopts trapezoidal shape, reduces the problem of natural cracking during butterfly optical cable is constructed in the prior art, has better torsional resistance.
2, the one-piece construction external diameter is little, lightweight, easy for installation.
3, having more stable properties of optical fiber cable, longer life-span, easier construction lays.
