Embodiment 1

[0044] Such as figure 1 , figure 2 and Figure 7 As shown, the optical fiber ribbon provided by this embodiment includes a plurality of core ribbon sets 10 arranged side by side, and the core ribbon sets 10 are provided with an adhesive part 20 and a separation part 30; the adhesive part 20 and the separation part 30 are spaced along the first direction and Arranged in a staggered manner between any adjacent core band groups 10, and the adhesive part 20 and the separation part 30 are spaced along the second direction and arranged in a staggered manner between any adjacent core band groups 10; the first direction is the core In the lengthwise direction of the belt set 10, the second direction forms an angle with the first direction.

[0045] In this embodiment, the first direction is the length direction of a single core ribbon set 10 , and the second direction is the direction in which multiple core ribbon sets 10 are arranged side by side. Take the formed optical fiber ri...

Embodiment 2

[0062] Please continue to refer image 3 and Figure 4 Preferably, each set of core strips 10 includes one core strip 11 , and the adhesive parts 20 and separation parts 30 are spaced apart and interlaced between any two adjacent core strips 11 .

[0063] In this embodiment, a set of core ribbons 10 includes one core ribbon 11 , and the colored layers 12 outside the core ribbon 11 are used to arrange multiple core ribbons 11 in an orderly manner according to a certain spectral order. Arrange in the longitudinal direction described in Embodiment 1 in the order of the spectrum, then a plurality of core strips 11 are arranged in the longitudinal direction, and adhesive resin is intermittently coated between any two adjacent core strips 11, thereby forming a network fiber optic ribbon.

Embodiment 3

[0065] Please continue to refer Figure 5 and Figure 6 , preferably, the plurality of sets of core ribbons 10 are respectively a first core ribbon set and a second core ribbon set; the first core ribbon set includes a plurality of core ribbons 11 , and the second core ribbon set includes one core ribbon 11 . Both sides of the second core band group along the second direction are respectively provided with the first core band group.

[0066] In this embodiment, there are two sets of first core bands, multiple sets of second core bands, and multiple sets of second core bands are arranged side by side between two sets of first core bands. Each set of second core bands includes a second core band, which is arranged according to the connection method of the single core band 11 in the second embodiment above. Each set of first core bands includes two first core bands, which are arranged according to the connection method of the single core band 11 in the first embodiment above. ...

Abstract

The invention provides an optical fiber ribbon, an optical cable and a manufacturing method of the optical fiber ribbon, and relates to the technical field of communication optical cables. The opticalfiber ribbon comprises a plurality of core ribbon groups which are arranged in parallel, wherein each core ribbon group is provided with an adhesive part and a separation part, the adhesive parts andthe separation parts are arranged between any two adjacent core belt groups at intervals in a staggered manner in the first direction, and the adhesive parts and the separation parts are further arranged between any two adjacent core belt groups at intervals in a staggered manner in the second direction, the first direction is the length direction of the core belt group, and the second directionand the first direction form an angle. The optical fiber ribbon is advantaged in that a technical problem that the optical fiber belt in the prior art cannot meet manufacturing requirements of large core number, high density and small size at the same time is solved.

Description

technical field [0001] The invention relates to the technical field of communication optical cables, in particular to an optical fiber ribbon, an optical cable and a method for manufacturing the optical fiber ribbon. Background technique [0002] With the rapid development of FTTH (Fiber To The Home, fiber-to-the-home) business, the pipeline resources for installing optical fibers are becoming increasingly tight, and the demand for optical cables with large core count, high density, and small size is often increasing. When used to manufacture optical fiber ribbons, several colored optical fibers are generally arranged and bonded together in an orderly manner according to a certain color spectrum, and the core ribbons are arranged in parallel without crossing. Although the above method can meet the manufacturing requirements of a large number of cores of the optical fiber ribbon, the formed optical fiber ribbon has a large size and a low density. [0003] In view of this, th...
