Abstract
The utility model discloses a band type optical cable with an SZ stranded structure. The band type optical cable comprises a plurality of band type optical fibers (1), wherein the band type optical fibers (1) are laminated and tightly combined with one another in an SZ stranding way to form a band type optical fiber body; the band type optical fiber body is in a sine wave bent state, and is wrapped by a sleeve (3); oil paste (2) is filled between the band type optical fiber body and the sleeve (3); a water-resisting wrapping band (4) covers the periphery of the sleeve (3) in an extrusion way; a combined band (5) is arranged on the periphery of the water-resisting wrapping band (4); a polyethylene sheath (6) wraps the periphery of the combined band (5); and reinforcement cores (7) are arranged in the polyethylene sheath (6). The band type optical cable has the advantages of great residual length, uniform residual length, low torsion stress and low cost.
Description
Technical field
The utility model relates to a kind of optical cable, is specifically related to a kind of optical fiber ribbon cable of SZ lay configuration.
Background technology
Usually the optical fiber in the optical cable is all through being inserted in pipe box behind the stranded composition fiber body of spiral.Spiral is stranded can to improve optical fiber excess length and bending property, and also have a following problem but spiral is stranded: 1, surplus length is inhomogeneous, and the fiber spiral radius of different layers is different in the same pipe box, causes the fiber lengths of central core short, and the fiber lengths of boundary layer is long; 2, twisting stress is big, and the stranded boundary layer fibre-optical bending degree that causes of spiral is high, receives bigger twisting stress, influences the life-span of optical fiber; 3, Yu Changxiao, the radius of spin receives the restriction of laminates such as pipe box, causes surplus length to be difficult to do greatly; 4, the stranded equipment price of spiral is expensive, causes production cost high.
The utility model content
The purpose of the utility model is to overcome the deficiency of prior art, and a kind of optical fiber ribbon cable of SZ lay configuration is provided, and it has surplus growing up, the advantage that surplus length is even, twisting stress is little and cost is low.
The purpose of the utility model realizes through following technical scheme:
A kind of optical fiber ribbon cable of SZ lay configuration is characterized in that, it comprises multi-ribbon shape optical fiber, and ribbon fiber is stacked together and combine closely through the stranded mode of SZ and to form the ribbon fiber body, and the ribbon fiber body is the case of bending of sinusoidal waveform;
The ribbon fiber body is wrapped up by sleeve pipe, is filled with ointment between ribbon fiber body and the sleeve pipe, and the peripheral extruding of sleeve pipe is coated with the band that blocks water, and the band outer periphery that blocks water is equipped with composite band, and the composite band periphery is enclosed with pe sheath, is provided with strengthening core in the pe sheath.
The advantage of the utility model is: 1, the ribbon fiber body is the sinusoidal waveform bending, and every ribbon fiber bending radius is consistent, makes the surplus length of ribbon fiber even; 2, under the situation of same diameter sleeve pipe, surplus length is promoted to 4% from 1.5% of conventional cable; 3, ribbon fiber body integral body is crooked with same radius, eliminates internal rigid, has reduced twisting stress; 4, the stranded equipment price of SZ is cheap, has reduced production cost.

Among the figure, 1-ribbon fiber, 2-ointment, 3-sleeve pipe, the 4-band that blocks water, 5-composite band, 6-pe sheath, 7-strengthening core.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further, the protection domain of the utility model is not limited to the following stated.
As depicted in figs. 1 and 2, a kind of optical fiber ribbon cable of SZ lay configuration, it comprises multi-ribbon shape optical fiber 1, and ribbon fiber 1 is stacked together and combine closely through the stranded mode of SZ and to form the ribbon fiber body, and the ribbon fiber body is the case of bending of sinusoidal waveform; The ribbon fiber body is by sleeve pipe 3 parcels; Be filled with ointment 2 between ribbon fiber body and the sleeve pipe 3, sleeve pipe 3 peripheral extruding are coated with the band 4 that blocks water, and band 4 outer periphery that block water are equipped with composite band 5; Composite band 5 is steel band or aluminium-plastic tape; Composite band 5 peripheries are enclosed with pe sheath 6, are provided with strengthening core 7 in the pe sheath 6, and strengthening core 7 can make optical cable possess certain pulling force ability to bear.
Claims (1)
1. the optical fiber ribbon cable of a SZ lay configuration is characterized in that, it comprises multi-ribbon shape optical fiber (1), and ribbon fiber (1) is stacked together and combine closely through the stranded mode of SZ and to form the ribbon fiber body, and the ribbon fiber body is the case of bending of sinusoidal waveform; The ribbon fiber body is wrapped up by sleeve pipe (3); Be filled with ointment (2) between ribbon fiber body and the sleeve pipe (3); The peripheral extruding of sleeve pipe (3) is coated with the band that blocks water (4); Band (4) outer periphery that blocks water is equipped with composite band (5), and composite band (5) periphery is enclosed with pe sheath (6), is provided with strengthening core (7) in the pe sheath (6).
