Definitions
- the present invention relates to an optical communication bundle and an optical cable comprising at least one such bundle.
- connection elements are in the form of bonding points based on epoxy acrylate resin which require cross-linking in order to ensure their solidification.
- the web can assume an unrolled position so as to form a ribbon (the optical fibers are coplanar), and a rolled up position so as to form a bundle (the fibers are then non-coplanar).
- the rolled up position has the advantage of being compact.
- the unrolled position lends itself particularly well to a connection of the layer with another layer of optical fibers. Indeed, it is easier in the unwound position to align and position each optical fiber of the sheet with an associated optical fiber of the other sheet, before welding them two by two in a single step commonly called "mass splicing ".
- connection elements proposed in the document EP3168665 are complex to attach to the optical fibers, which generates a non-negligible additional cost of manufacturing these bundles of optical fibers.
- connection elements generally made of acrylate, are mechanically fragile and can break during installation or when exposed to high temperatures. This generates a loss of unity of the fiber sheet.
- connection elements do not make it possible to easily vary the distance which separates two adjacent optical fibers when the sheet is unrolled.
- This constraint makes the step of aligning the optical fibers of the sheet more delicate, which must be carried out before the optical fibers of the sheet are subject to mass splicing with other optical fibers.
- the optical fibers may need to be positioned in parallel grooves of a support before ground splicing, and the distance between two adjacent grooves may not match. not to the distance between the respective centers of two adjacent optical fibers of the sheet. In this case, it may be necessary to break connection elements, which is tedious.
- An object of the present invention is to obtain an arrangement of optical fibers that is compact and can more easily be the subject of mass splicing with other optical fibers.
- an optical communication bundle comprising a sheet, the sheet comprising:
- optical fibers together defining a first side of the sheet and a second side of the sheet opposite the first side
- weft thread interlaced with the optical fibers to hold the optical fibers together, in which the weft thread extends alternately on the first side and on the second side of the web, crossing the web from the first side to the second side and from the second side to the first side, wherein:
- the sheet has a position wound on itself so as to form a bundle in which the optical fibers are non-coplanar
- the interlacing of the weft yarn with the optical fibers is adapted to allow the web to pass from the rolled up position to an unrolled position in which the optical fibers are coplanar.
- Interlacing with the weft yarn has the effect of maintaining an organized arrangement of the fibers within the web in its rolled-up position.
- the beam therefore has a compact shape.
- the interlacing achieved also makes it possible to very easily move the sheet from its rolled up position to its unrolled position, which is conducive to mass splicing, without substantial disruption of the optical fibers.
- the interlacing is advantageous because it can be configured more or less loosely, which makes it possible to be able to adjust the distance which separates an optical fiber from the sheet from a fiber which is adjacent to it, while maintaining the fibers optics to each other. Consequently, a user has a certain margin of maneuver to align the optical fibers of the sheet in the unwound position with other optical fibers, before implementing a mass splicing.
- This room for maneuver is particularly advantageous because it makes it possible to easily position the optical fibers in parallel grooves of different dimensions, before mass splicing.
- the proposed beam may also include the following characteristics, taken alone or combined with each other when technically possible.
- the interlacing of the weft yarn with the optical fibers is adapted so that, in the unwound position, the distance between a first optical fiber of the sheet and a second optical fiber of the sheet adjacent to the first optical fiber is less or equal to 150 ⁇ m, or even less than or equal to 70 ⁇ m.
- the interlacing of the weft yarn with the optical fibers is adapted so that, in the unwound position, the distance between any given optical fiber of the sheet and each optical fiber of the sheet adjacent to the given optical fiber is less than or equal to 150 ⁇ m, or even less than or equal to 70 ⁇ m.

- a method for obtaining an optical communication beam comprising:
- the method for obtaining according to the third aspect can also comprise a step of winding a holding wire around the bundle so as to keep the web in the rolled-up position on itself.
- a method for connecting a communication bundle according to the first aspect with additional optical fibers to be connected comprising:
- Figures 1 to 3 are three perspective views from above of a layer of optical fibers according to a first embodiment, in an unrolled position.
- FIG. 4 comprises four cross-sectional views of a sheet according to a second embodiment at different stages of a process implemented to obtain it.

- Fig. 7 is a sectional view of the optical communication beam according to the first embodiment.
- Figure 8 is a side view of an optical communication beam according to a second embodiment.
- Figure 9 is a sectional view showing a section of a cable according to one embodiment.
- Each optical fiber 2 has an elongated shape along a longitudinal axis X (for readability, only one of these axes X is represented in FIG. 1).
- Each optical fiber 2 typically comprises a core centered on its longitudinal axis, and a sheath surrounding the core (not shown).
- each optical fiber 2 has a cylindrical shape of revolution (therefore of circular section).
- the optical fibers 2 typically have identical diameters, for example of the order of 250 ⁇ m or 200 ⁇ m, or even less than 200 ⁇ m.
- the optical fibers 2 are arranged parallel to each other, that is to say that their respective longitudinal axes X are all parallel to the same direction, called the longitudinal direction.
- the sheet 1 has a first side (visible in Figure 1) and a second side opposite the first side (not visible in Figure 1).
- the optical fibers 2 together define the first side of the layer, as well as the second side of the layer opposite the first side.
- the sheet 1 also comprises a weft thread 3 interwoven with the optical fibers 2 to hold the optical fibers 2 relative to each other, that is to say limit their relative movement within the sheet.
- the weft yarn 3 extends alternately on the first side of the ply and on the second side of the ply, crossing the ply from the first side towards the second side and from the second side towards the first side.
- the way in which a weft yarn 3 is interlaced with the optical fibers 2 will be more fully detailed below.
- the sheet 1 is capable of adopting a so-called "unrolled" position (as opposed to a rolled up position which will be described later), which is represented in FIG. 1.
- the optical fibers are coplanar (ideally, their longitudinal axes pass through the same plane).
- the web is substantially flat, and thus forms a ribbon.
- the optical fibers 2 In the unrolled position of the web 1, the optical fibers 2 have different respective positions in a transverse direction perpendicular to the longitudinal direction. This transverse direction is parallel to the Y axis shown in Figure 1.
- the length of the web 1 is measured in the longitudinal direction
- the width of the web is measured in the transverse direction when the web is in the unrolled position
- its thickness is measured in a direction Z perpendicular to the plane when the web is in the unrolled position.
- the sheet 1 comprises a first extremal optical fiber 2a, a second extremal optical fiber 2b, and N-2 intermediate optical fibers 2c.
- each intermediate optical fiber 2c is adjacent to two other optical fibers of the layer 1 in the transverse direction;
- each extremal optical fiber 2a, 2b is on the other hand adjacent to a single intermediate optical fiber 2c of the web 1 in the transverse direction;
- the web 1 consists of different portions in the longitudinal direction X, portions which are called sections in the following.
- the web notably comprises a first section 1a and a second section 1b which is adjacent to the first section 1a in the sense that it extends the first section 1a in the longitudinal direction X.
- the weft thread 3 comprises a first portion of thread 3a interwoven with the optical fibers 2 in the first section 1a.
- the first wire portion 3a extending substantially rectilinearly in a first direction not parallel to the longitudinal direction, this first direction being indicated by the straight line Da in FIG. 3.
- the term substantially here refers to the fact that the first wire 3a crosses the sheet 1. In other words, even if the trajectory of the first yarn 3a appears rectilinear in FIGS. 1 to 3, this first yarn 3a extends, due to its intertwining, in a first plane parallel to the straight line Da and perpendicular to the plane (X, Y).
- the oriented angle a between the first direction and the longitudinal direction is strictly greater than 0 degrees and strictly less than 90 degrees.
- the weft yarn 3 also comprises a second portion of yarn 3b, which extends the first portion of yarn 3a.
- the second wire portion 3b is interlaced with the optical fibers 2 in the second section 1b.
- the second portion of wire 3b is interlaced with the optical fibers 2 in the second section 1b.
- the second wire portion 3a extends substantially rectilinearly in a second direction not parallel to the longitudinal direction, indicated by the straight line Db in FIG. 3.
- the term substantially refers here to the fact that the second thread 3b crosses web 1. In other words, even if the trajectory of thread 3b appears rectilinear in FIGS. 1 to 3, this second thread 3b extends, due to its interlacing, in a second plane parallel to the straight line Db and perpendicular to the plane (X, Y).
- the oriented angle ⁇ between the second direction and the longitudinal direction is strictly greater than 0 degrees and strictly less than -90 degrees.
- the second direction is different from the first direction.
- the second plane is secant with the first plane.
- the sum of the lengths of the first section and of the second section in the longitudinal direction is preferably less than 50 millimeters, or even is between 1 and 15 millimeters.
- the two sections 1a and 1b are of identical lengths, which amounts to saying that the wire portions 3a and 3b consume as much sheet length to go from one of the extremal optical fibers to the other.
- the weft thread 3 is made of a material chosen from the group consisting of polyester, cotton, polyamide, polypropylene and one of their derivatives. These materials have the advantage of resisting exposure to high temperatures (typically above 120°C).
- the diameter of the weft thread 3 is smaller than the diameter of the optical fibers 2.
- the weft yarn 3 has a linear density strictly less than 11 tex. This linear mass can be greater than 1 tex.
- the ply 1 can of course include other sections in which other portions of the weft yarn 3 repeat the pattern formed by the yarn portions 3a and 3b.
- the weft thread 3 can thus have a trajectory in the (X, Y) sawtooth plane as can be seen in Figures 1 to 3.
- a process for obtaining the sheet 1 from the optical fibers 2 and the weft yarn 3 comprises the following steps.
- the optical fibers 2, which are arranged in the longitudinal direction, are divided into two rows separated by a space: an upper row and a lower row.
- two adjacent optical fibers 2 are systematically assigned to different rows, as can be seen in sub-step E1 of FIG. 4.
- the two rows have the same number of optical fibers 2, one fiber close.
- N 12.
- N were odd, one of the two rows would have one more optical fiber 2 than the other row.
- the optical fibers 2 of the same row are all coplanar.
- the respective longitudinal axes of the optical fibers 2 of the upper row if there are several of them, are all in the same plane called the upper plane
- the respective longitudinal axes of the optical fibers 2 of the lower row if there are several, are all in the same plane called lower plane.
- the first wire portion 3a is inserted into the space between the two rows of optical fibers 2, so that this wire portion 3a extends parallel to the upper and lower planes, in the first direction.
- a second sub-step E2 the upper row is moved downwards, so that the two rows intersect.
- the optical fibers 2 of the upper row come into contact with the wire at different points, and cause a deformation of this wire so that the latter adopts a zig-zag shape, as can be seen in the sectional views of Figure 4.
- the two rows are moved away from each other so as to form a second space between them, for example of width equivalent to the space discussed previously.
- the second wire portion 3b is inserted into the newly formed second space between the two rows of optical fibers 2, so that the second wire portion 3b extends parallel to the upper and lower planes, in the second direction.
- a fourth sub-step E4 the two rows of fibers are brought together so that all the optical fibers 2 are all coplanar with each other.
- the second portion of wire 3b is stressed by the two rows of optical fibers so that the second portion of wire 3b adopts a zig-zag shape, just like the first portion of wire 3a.
- a tensile force is if necessary applied to the weft thread 3, so as to tighten its thread portions 3a, 3b against the optical fibers 2.
- the interlacing of the wire portions 3a and 3b with the optical fibers 2 is finished at the end of this fourth sub-step E4.
- first wire portion 3a and the second wire portion 3b each extend alternately on the first side and on the second side of the ply, crossing the ply from the first side towards the second side and from the second side to the first side.
- the preceding steps can be repeated for other threads (or portions of the same thread) to be interlaced with the optical fibers 2 within the layer 1.
- each of the optical fibers 2 is confined between the two wires 3a and 3b in the views of Figures 1 to 3.
- the interlacing achieved makes it possible to adjust with some flexibility the distance which separates two adjacent fibers of the web in its unrolled position.
- the interlacing of the weft yarn 3 with the optical fibers is adapted so that the web meets a specific criterion in its unrolled position: this criterion, illustrated in FIG. 5, consists in imposing that the distance G which separates one of the optical fibers of the sheet 1 from another of the optical fibers of the sheet 1 which is adjacent to it is less than or equal to a maximum value Gmax. In other words, we have 0 ⁇ G ⁇ Gmax.
- the distance G between two fibers is measured edge to edge while the two fibers are parallel; in other words, it corresponds to the width of the gap between these two fibres, which is crossed in particular by the weft thread 3, if applicable.
- a person skilled in the art verifies whether the aforementioned distance criterion G ⁇ Gmax is verified by two adjacent optical fibers 2 of the web 1 in its unwound position. For this, the person skilled in the art separates the two end optical fibers 2a, 2b from each other until the weft thread 3 is taut, while the web 1 is in the unwound position, while ensuring that the fibers remain parallel, and measures the distance G between two mutually adjacent optical fibers 2.
- the person skilled in the art tightens the weft yarn 3 more around the optical fibers and repeats the preceding verification until the criterion G ⁇ Gmax is verified.

- the weft yarn 3 is not represented in FIG. 7.
- the dotted line indicates the adjacency links between the optical fibers 2, and how these reorganize when the web 1 passes from the wound position to the unwound position (shown in FIG. 5).
