Optical communication bundle and associated optical cable

A method of connecting an optical communicating bundle with additional optical fibers, wherein the optical communication bundle comprises a layer, the layer comprising:

• at least three parallel optical fibers, a weft yarn interwoven with the optical fibers to hold the optical fibers together, wherein the layer has a rolled-up position in which the layer forms a roll and the optical fibers are non-coplanar, and wherein the weft yarn is interwoven with the optical fibers to allow the layer to go from the rolled position to an unrolled position in which:
• the optical fibers are coplanar, the optical fibers together define a first side of the layer and a second side of the layer opposite the first side, the weft yarn extends alternately over the first side and over the second side of the layer by traversing the layer from the first side to the second side and from the second side to the first side, and a distance between a first optical fiber of the layer and a second optical fiber of the layer adjacent to the first optical fiber is less than or equal to 150 μm,
• wherein the method comprises:
• making the layer go from the rolled position to the unrolled position,
• aligning each optical fiber of the layer with one of the additional optical fibers,
• connecting the aligned optical fibers pairwise while the layer is in the unrolled position.
