Problems solved by technology

Therefore, in order to ensure the reliable operation of communication equipment and networks in places requiring low-smoke, halogen-free flame retardant, it is necessary to effectively solve the fire hazards caused by the burning and dripping of optical cables in case of fire, and the fact that optical cables are prone to release a large amount of black in a burning fire. Thick smoke and toxic gases cause secondary environmental pollution and difficulty in escaping

Embodiment 1

[0035] Such as figure 1As shown, the present invention provides a composite ribbon cable, comprising a first optical fiber part 1, a second optical fiber part, a third optical fiber part and a metal strengthening core 2, the first optical fiber part 1, the second optical fiber part and the third optical fiber part Evenly distributed in the insulating layer 4 , the metal reinforcing core 2 is arranged in the middle of the insulating layer 4 . A water-blocking layer 5 is arranged outside the insulating layer 4, a shielding layer 6 is arranged outside the water-blocking layer 5, a reinforcing layer 7 is arranged outside the shielding layer 6, an outer sheath 8 is arranged outside the reinforcing layer 7, and the reinforcing layer 7 is made of aramid yarn.

[0036] Such as image 3 As shown, the first optical fiber part 1 includes an accommodating part 101 and an optical fiber ribbon 103. The accommodating part 101 is a diamond-shaped frame, and the inner cavity of the rhombic fr...

Embodiment 2

[0043] Such as figure 2 As shown, the difference between this embodiment and Embodiment 1 is that a filling rope 15 is arranged between the first optical fiber part 1, the second optical fiber part and the third optical fiber part, so as to reduce the gap between each optical fiber part, and the filling rope 15 simultaneously Also plays a protective role. A steel wire reinforcement core can also be arranged between each optical fiber part to improve the structural strength of the entire optical fiber cable.

Embodiment 3

[0045] A fuel retardant paste, comprising components by mass: 78 parts of base oil, 9 parts of compound thickener, 0.8 part of flame retardant, and 0.5 part of antioxidant.

[0046] The base oil is hydrogenated paraffin base oil / hydrogenated naphthenic oil mixed oil, and the mass ratio is 2:3; the composite thickener is polyacrylamide / fatty alcohol polyoxyethylene ether, and the mass ratio is 5: 7; the flame retardant is triallyl isocyanurate and nano-tin powder, the mass ratio is 90:0.15, wherein triallyl isocyanurate is a thermal crosslinking agent, and nano-tin powder is a catalyst ; The antioxidant is tertiary butyl hydroquinone.

Abstract

The invention discloses a composite ribbon optical cable. The optical fiber comprises a first optical fiber part, a second optical fiber part, a third optical fiber part and a first metal reinforcingcore; the first optical fiber part, the second optical fiber part and the third optical fiber part are uniformly distributed in an insulating layer; a first water blocking layer is arranged outside the insulating layer, a first shielding layer is arranged outside the first water blocking layer, a reinforcing layer is arranged outside the first shielding layer, and an outer sheath is arranged outside the reinforcing layer; the first optical fiber part comprises a containing part and an optical fiber ribbon, the containing part is a rhombic frame body, a second metal reinforcing core is arrangedin an inner cavity of the rhombic frame body, and a PE cushion layer is arranged outside the second metal reinforcing core; the rhombic frame body comprises a first side edge, a second side edge, a third side edge and a fourth side edge, and the first side edge, the second side edge, the third side edge and the fourth side edge are each provided with a rectangular groove; the optical fiber ribbonis arranged in the rectangular grooves. The tensile property and water resistance of the optical fiber are good, and meanwhile, the optical fiber is good in flame-retardant effect, high in transmission capacity, high in speed, good in anti-interference performance and suitable for being applied to occasions with large-scale networks.

Description

technical field [0001] The invention relates to an optical fiber cable, in particular to a composite ribbon optical cable. Background technique [0002] Optical fiber communication has been widely used due to its advantages of large information capacity, good confidentiality, light weight, small size, and long distance without repeaters. Broader and deeper levels of development. The application of optical fiber is bringing profound impact and changes to human life. The existing optical fiber cables have insufficient strength and tensile strength, and there are hidden dangers of breaking during the winding process and at both ends of the cable. Their functions are single, and there is a lot of inconvenience in the current signal transmission process. It needs to be equipped with both optical and electrical cables, but the optical fiber is usually not resistant to bending, which will cause the optical fiber to break. [0003] The invention patent with the publication number...
