Problems solved by technology

[0002] In the prior art, the central beam tube type optical cable mainly has several structures: one is GYXTW, GYDXTW and extended products, which consist of a central beam tube, located in the central beam The reinforcing band outside the tube, the reinforcing member located outside the reinforcing band, and the sheath covering the reinforcing band and the reinforcing member. The reinforcing member is located in the sheath and is not easy to peel off. When the reinforcing member is used to transmit power at the same time, it also exists Corresponding technical problems, and the electric heating greatly affects the optical fiber communication. In addition, in order to reduce the cost, there are also flat reinforcements, such as CN200950171U
The second is GYXTS, GYXTA and extended products, which are composed of a central bundle tube, a plurality of stranded reinforcements located outside the central bundle tube, a protective belt located outside the reinforcement, and a sheath covering the protective belt. This structure has strong tensile, compressive and impact resistance, but it requires expensive steel wire stranding equipment, and the equipment occupies a large area, requires troublesome maintenance, requires production personnel, needs power supply, needs lighting, etc., for production-oriented enterprises For this reason, it is difficult to recover the cost in a short period of time, and it increases the cost of the product virtually and reduces the competitiveness; and during stranding production, the extremely fine steel wire will be twisted and misplaced, which is extremely difficult in production and inspection. Discovered, but buried a huge quality problem for the product

Embodiment 1

[0028] please see Figure 1 to Figure 4 , a central bundle tube type optical cable, has four accommodating parts 1, a plurality of strengthening parts 2, a central loose tube 3, a plurality of optical fibers 4, and an outer sheath 5, and the optical fiber 4 is located in the central loose tube 3 , the reinforcing part 2 is located outside the central loose tube 3, the reinforcing part 2 is located in the housing part 1, the housing part 1 is located outside the central loose tube 3, and the outer sheath 5 is located outside the housing part 1; its characteristics That is: the accommodating part 1 is composed of a first arc-shaped part 11, a connecting part 12, a second arc-shaped part 13, a first limiting part 111, and a second limiting part 113. The first arc-shaped part 11 and the second The two arc parts 13 are all in the shape of an arc cylinder, and the connecting part 12 is located between the first arc part 11 and the second arc part 13 and connects the two together. Th...

Embodiment 2

[0038] please see Figure 5 to Figure 8 ,refer to Figure 1 to Figure 4 , a central bundle tube type ribbon optical cable, which is basically the same as that of Example 1, except that: one of them is that the first accommodating chamber 112 and the second accommodating chamber 114 all have surrounding loose tubes 6, and the surrounding There are multiple light guide fibers 7 in the loose tube 6; there is at least one loose tube around each first accommodating cavity or in each second accommodating cavity; the second is: there is no central loose tube, all The upper surface of the second arc-shaped part 13 of the accommodating part 1 encloses a central cavity; in the central cavity there are a plurality of optical fiber ribbons 8 stacked together, and each optical fiber ribbon 8 has a plurality of optical conductors 9 in it.

[0039] That is: a central bundle tube type ribbon optical cable, which has a plurality of accommodating parts 1, a plurality of surrounding loose tubes...

Embodiment 3

[0041] please see Figure 9 ,refer to Figure 1 to Figure 8 , a central bundle tube type ribbon optical cable, basically the same as the implementation example 1, the difference is that: one of them is: there is no reinforcing part 2, and there are surroundings in the first accommodating cavity 112 and the second accommodating cavity 114. The loose tube 6 has a plurality of light guide fibers 7 in the surrounding loose tube 6; each first accommodating cavity or each second accommodating cavity has at least one surrounding loose tube 6; the second is: the center The loose tube 3 has a plurality of optical fiber ribbons 8 stacked together, and each optical fiber ribbon 8 has a plurality of optical conductors 9 in it.
