Abstract

The fibres are mounted on a jig consisting of a rigid primary support(s) made of hard metal or glass with two major V-shaped grooves parallel to and near to the lateral sides. In the middle part are a row of V-grooves (20) to locate the fibres, these are optimally half the depth of the dia. of the fibres and have a 60 degree angle. The support is covered by a thin auxiliary support (2) of an auto polymerising resin based on methacrylate of methyl. The covering of the fibres is stripped back and the fibres are encapsulated in a synthetic resin. When the resin has hardened the fibres are sawn across two parallel planes and the middle section removed. The sawn ends are placed end to end with a liquid or polymerising resin of index of refraction close to the fibres in between. The positioning of the joint is assisted by two guiding cylinders which slide in the major grooves.

Description

Procédé de raccordement de fibres optiques disposées en nappe dans un câble et dispositif de mise en oeuvre du procédé.Method for connecting optical fibers arranged in a sheet in a cable and device for implementing the method.

La présente invention porte sur le raccordement de fibres optiques disposées en nappe dans un câble, éventuellement après développement de la nappe selon un ruban plat, tel que décrit dans le brevet principal ; elle porte plus particulièrement sur un perfectionnement du dispositif de mise en oeuvre du procédé. The present invention relates to the connection of optical fibers arranged in a sheet in a cable, optionally after development of the sheet according to a flat ribbon, as described in the main patent; it relates more particularly to an improvement of the device for implementing the method.

Le procédé de raccordement de fibres optiques décrit dans le brevet principal permet d'opérer simultanément sur la nappe de fibres se présentant sous forme d'un ruban plat emprisonnant entre ses parties supérieure et inférieure la nappe de fibres, il est facilement utilisable sur chantier. The method of connecting optical fibers described in the main patent makes it possible to operate simultaneously on the sheet of fibers which is in the form of a flat ribbon trapping between its upper and lower parts the sheet of fibers, it is easy to use on site.

Selon le brevet principal, le procédé de raccordement consiste - à séparer les parties supérieure et inférieure du ruban emprisonnant les fibres, - à couper et séparer lesdites parties supérieure et inférieure sur une longueur permettant de dégager une zone de Jonction pour les fibres, - à poser les fibres à raccorder dans des vés de positionnement d'une plaquette, - à déposer sur une partie des fibres à raccorder disposées sur la plaquette, jusqu'à leurs extrémités, une colle ou une résine synthétique, puis à disposer, sur les longueurs encollées des fibres, un couvercle presseur, - après durcissement de la colle ou résine synthétique, à scier à écartement constant dans des plans parallèles l'ensemble constitué de la plaquette des fibres et du couvercle et à retirer la zone comprise entre les plans de sciage, - à remettre bout à bout les parties subsistantes de la plaquette de part et d'autre des plans de sciage, avec coIncidence des extrémités des fibres, en interposant un liquide ou une résine polymérisable d'indice de réfraction voisin de celui du coeur des fibres, puis à presser les parties subsistantes de la plaquette l'une contre l'autre et les immobiliser. According to the main patent, the connection method consists of - separating the upper and lower parts of the ribbon trapping the fibers, - cutting and separating said upper and lower parts over a length making it possible to release a junction zone for the fibers, - to place the fibers to be connected in positioning ves of a wafer, - to deposit on a part of the fibers to be connected arranged on the wafer, to their ends, an adhesive or a synthetic resin, then to arrange, along the lengths glued fibers, a pressure cover, - after hardening of the glue or synthetic resin, to saw at constant spacing in parallel planes the assembly consisting of the fiber board and the cover and to remove the area between the sawing planes , - to place end to end the remaining parts of the wafer on either side of the sawing planes, with coincidence of the ends of the fibers, by interposing a liquid or a polymerizable resin with a refractive index close to that of the core of the fibers, then pressing the remaining parts of the wafer one against the other and immobilizing them.

Les parties subsistantes de la plaquette sont mises bout à bout dans les plans de sciage, en disposant des cylindres de guidage dans des vés de dimensions importantes disposés latéralement sur la plaquette et d'axes parallèles aux axes des fibres. The remaining parts of the wafer are placed end to end in the sawing planes, by arranging guide cylinders in ves of large dimensions arranged laterally on the wafer and with axes parallel to the axes of the fibers.

La plaquette utilisée pour la mise en oeuvre de ce procédé est de forme générale rectangulaire et comporte dans sa zone centrale une rangée de vés de largeur telle que les fibres optiques peuvent s'y loger1 mais en restant en saillie par rapport à la race supérieure de la plaquette, et, de chaque côté, des vés de dimensions importantes permettant chacun le logement d'un cylindre de guidage. The plate used for the implementation of this process is generally rectangular in shape and has in its central zone a row of ves of width such that the optical fibers can be housed there 1 but remaining projecting with respect to the upper race of the plate, and, on each side, ves of large dimensions each allowing the housing of a guide cylinder.

La plaquette utilisée était en métal ductile et obtenue par emboutissage ou en matériau thermoplastique et obtenue par moulage,
Une telle plaquette qui présente l'avantage de présenter un cout d'obtention bas, n'est cependant pas nécessairement satisfaisante eu égard aux contraintes thermiques que l'on rencontre dans un environnement de chantier (-10 + OOC) entrarnant des perturbations mécaniques et donc des fluctuations de la perte d'insertion.The wafer used was made of ductile metal and obtained by stamping or of thermoplastic material and obtained by molding,
Such a wafer which has the advantage of having a low cost of production, is however not necessarily satisfactory having regard to the thermal stresses encountered in a work site environment (-10 + OOC) involving mechanical disturbances and therefore fluctuations in insertion loss.

La présente invention a pour but, notamment dans de telles conditions de variations thermiques, d'assurer un maintien des qualités optiques et géométriques des raccordements effectues. The object of the present invention is, in particular in such conditions of thermal variations, to ensure maintenance of the optical and geometric qualities of the connections made.

Elle a pour objet un dispositif de mise en oeuvre du procédé selon le brevet principal comportant un support rigide dit support principal de forme générale rectangulaire et un support auxiliaire en couche mince recouvrant au moins la zone longitudinale médiane de l'une des grandes faces du support- principal et présentant une rangée de vés de positionnement des fibres optiques à raccorder ouverts sur l'une des faces dite face supérieure du dispositif. It relates to a device for implementing the method according to the main patent comprising a rigid support known as a main support of generally rectangular shape and an auxiliary support in a thin layer covering at least the median longitudinal zone of one of the large faces of the support. - Main and having a row of ves for positioning the optical fibers to be connected open on one of the faces known as the upper face of the device.

Selon une autre caractéristique, le support principal comporte deux vés de grande dimension au voisinage de ses bords latéraux et de part et d'autre de la rangée de vés de logement des fibres, recouverts intérieurement par ledit support auxiliaire et destinés à recevoir chacun un cylindre de guidage. According to another characteristic, the main support comprises two large ves in the vicinity of its lateral edges and on either side of the row of fiber housing ves, covered internally by said auxiliary support and each intended to receive a cylinder guide.

Dans une réalisation selon cette addition, le support principal est en métal dur ou en verre, le support auxiliaire est avantageusement en une résine autopolymérisante à base de méthacrylate de méthyle. In an embodiment according to this addition, the main support is made of hard metal or glass, the auxiliary support is advantageously made of a self-curing resin based on methyl methacrylate.

D'autres caractéristiques et avantages de ce dispositif appa raîtront au cours de la description qui en est faite ci-après en - la figure 1 représente en coupe transversale une plaquette support de fibres à raccorder, conforme à la présente addition - la figure 2 est une coupe transversale d'un ensemble formé à partir de cette plaquette sur laquelle les fibres à raccorder ont été fixées, - la figure 3 est une vue de dessus de l'ensemble et illustre l'une des étapes du procédé de raccordement. Other characteristics and advantages of this device will appear during the description which is given below in - Figure 1 shows in cross section a fiber support plate to be connected, in accordance with this addition - Figure 2 is a cross section of an assembly formed from this plate on which the fibers to be connected have been fixed, - Figure 3 is a top view of the assembly and illustrates one of the steps of the connection process.

La plaquette selon la présente addition, utilisée pour le raccordement de fibres optiques appartenant à deux nappes, est illustrée dans la figure 1. Elle comporte un support rigide, dit support principal 1 de forme générale rectangulaire et un support auxiliaire 2 recouvrant les deux grandes et les deux petites faces du support principal. The plate according to the present addition, used for the connection of optical fibers belonging to two layers, is illustrated in FIG. 1. It comprises a rigid support, said main support 1 of generally rectangular shape and an auxiliary support 2 covering the two large and the two small faces of the main support.

Le support principal 1 a ses faces planes, exception faite des deux portions latérales de l'une de ses grandes faces, ici la face supérieure, qui présentent deux rainures longitudinales en vé respectivement, 11 et 12. Ces deux rainures 11 et 12, de part et d'autre de la zone longitudinale médiane plane de la face supérieure du support principal, sont de largeur et profondeur très supérieures aux dimensions transversales des fibres à connecter qui seront reçues par la plaquette. The main support 1 has its flat faces, except for the two lateral portions of one of its large faces, here the upper face, which have two longitudinal grooves in vee respectively, 11 and 12. These two grooves 11 and 12, of on either side of the flat median longitudinal zone of the upper face of the main support, are of width and depth much greater than the transverse dimensions of the fibers to be connected which will be received by the wafer.

Le support auxiliaire 2 définit sur la surface supérieure du support principal un support en couche mince. Il présente, au niveau de la zone longitudinale médiane du support principal, une rangée de rainures en vés 20 destinées au positionnement des fibres. Il recouvre, toujours en couche mince, de part et d'autre de cette rangée de rainures 20, les parois internes des rainures 11 et 12 précitées en délimitant de nouvelles rainures 21 et 22 et forme sous la face inférieure du support principal une embase d'épaisseur plus importante. Ses rainures 20 s'étendent, comme les rainures 21 et 22 avec lesquelles elles sont parallèles, sur la longueur de la plaquette elles sont de dimensions rigoureusement identiques et en nombre correspondant au nombre de couples de fibres à raccorder.Avantageusement, elles sont d'angle 60 et de profondeur supérieure d'environ 50% au diamètre des fibres à raccorder, leur largeur étant alors telle que les fibres optiques pourront s'y loger partiellement en
telle que les fibres optiques pourront s'y loger partiellement en
restant en saillie sur la face supérieure de la plaquette.The auxiliary support 2 defines a thin layer support on the upper surface of the main support. It has, at the median longitudinal region of the main support, a row of v-shaped grooves 20 intended for positioning the fibers. It covers, still in a thin layer, on either side of this row of grooves 20, the internal walls of the aforementioned grooves 11 and 12 by delimiting new grooves 21 and 22 and forms a base plate under the underside of the main support. 'greater thickness. Its grooves 20 extend, like the grooves 21 and 22 with which they are parallel, over the length of the wafer they are of strictly identical dimensions and in number corresponding to the number of pairs of fibers to be connected. Advantageously, they are of angle 60 and a depth of about 50% greater than the diameter of the fibers to be connected, their width then being such that the optical fibers can be accommodated therein in part
such that the optical fibers can be housed there partially in
remaining projecting from the upper face of the plate.

Le support principal 1 est en verre, les rainures en vés 11 et 12 y seront taillées dans sa face supérieure au voisinage de ses bords longitudinaux. En variante, il peut également être en métal dur, les rainures 11 et 12 y seront alors usinées. The main support 1 is made of glass, the vee grooves 11 and 12 will be cut there in its upper face in the vicinity of its longitudinal edges. Alternatively, it can also be made of hard metal, the grooves 11 and 12 will then be machined there.

Le support auxiliaire 2 est en une résine autopolymérisante avantageusement à base de méthacrylate de méthyle, il peut être obtenu par moulage sur le support principal. The auxiliary support 2 is made of a self-curing resin advantageously based on methyl methacrylate, it can be obtained by molding on the main support.

En regard de la figure 2, on voit que des fibres telles que 3 positionnées dans les rainures 20 du support auxiliaire 1, sont maintenues dans leurs logements au moyen d'un couvercle presseur X, les fibres ayant été enrobées préalablement à la pose du couvercle presseur d'une colle ou résine 5 qui assure l'assemblage des divers éléments en l'ensemble compact illustré. With reference to FIG. 2, it can be seen that fibers such as 3 positioned in the grooves 20 of the auxiliary support 1, are held in their housings by means of a presser cover X, the fibers having been coated prior to the fitting of the cover presser of an adhesive or resin 5 which assembles the various elements into the compact assembly illustrated.

En regard de la figure 3, qui illustre vu de dessus ensemble
compact obtenu selon la figure 2, on voit outre les fibres 3 main
tenues dans un ruban plat 30, qui est par exemple un élément alvéolé,
et appartenant à l'une des nappes, des fibres 6 maintenues dans un
ruban plat analogue 60 appartenant à l'autre nappe. Les fibres 3 et 6
sont dénudées sur leurs portions terminales, l'extrémité de la par
tie supérieure de l'un et l'autre des rubans 30 et 60 étant collée
sur le couvercle presseur 4. Dans cet ensemble compact, les extré
mités des paires de fibres à connecter sont sans précision particu
lière sur leurs écartements, ni rectification préalable de leurs
faces frontales ; aucune précaution particulière étant nécessaire, à
ce stade, quant à l'alignement des extrémités des fibres de chacune
des nappes et à l'état de surface de leurs faces frontales.Next to Figure 3, which illustrates seen from above together
compact obtained according to figure 2, we see besides the 3 hand fibers
held in a flat ribbon 30, which is for example a honeycomb element,
and belonging to one of the layers, fibers 6 held in a
similar flat ribbon 60 belonging to the other tablecloth. Fibers 3 and 6
are stripped on their terminal portions, the end of the par
upper tie of both of the ribbons 30 and 60 being glued
on the presser cover 4. In this compact set, the extr
mites of the pairs of fibers to be connected are unspecified particu
link on their spacings, nor prior rectification of their
front faces; no special precautions being necessary, except
this stage, as for the alignment of the ends of the fibers of each
layers and the surface condition of their front faces.

Cette figure 3 représente, aussi, l'opération de double sciage de l'ensemble compact obtenu. Ce double sciage est effectué avec soin selon deux plans de coupe 7 et 8 rigoureusement parallèles entre eux et rigoureusement perpendiculaires aux fibres de l'une ou l'autre des nappes respectives pour venir sectionner toutes les fibres de chacune des nappes en donnant une planéité rigoureuse et un etat de surface pratiquement parfait aux faces frontales des fibres de chacune des nappes.  This FIG. 3 also represents the double sawing operation of the compact assembly obtained. This double sawing is carried out with care along two cutting planes 7 and 8 which are strictly parallel to each other and strictly perpendicular to the fibers of one or other of the respective plies in order to cut all the fibers of each of the plies, giving a rigorous flatness. and a practically perfect surface condition at the front faces of the fibers of each of the layers.

Après rejet de la portion entre ces plans de coupe, et nettoyage des faces des deux demi-ensembles restants, ceux-ci seront assemblés bout à bout pour réaliser le raccordement entre fibres. Pour cet assemblage, les faces des deux demi-ensembles seront avantageusement encollées, la colle utilisée pour le plan de jonction étant choisie à coefficient de transmission supérieur à 90%, pour une pression exercée selon les nappes de fibres d'environ 1 à 1,8 millibar, et souple pour supporter les tensions éventuelles résultant des différences de dilatation des matériaux successifs considérés selon la hauteur de ce plan de jonction ;une telle colle sera par exemple une résine polymérisable d'indice de réfraction voisin de celui du coeur des fibres.Les deux demi-ensembles ramenés bout à bout, seront repositionnés correctement au moyen de deux cylindres de guidage, ici non illustrés, insérés respectivement dans les rainures latérales en vés 21 et 22, chacune également coupée mais dont les deux parties restantes sont ramenées jointives puis serrées l'une contre l'autre selon les nappes de fibres. On réalise ainsi un raccordement fixe entre fibres appartenant à deux nappes initiales. After rejecting the portion between these cutting planes, and cleaning the faces of the two remaining half-assemblies, these will be assembled end to end to make the connection between fibers. For this assembly, the faces of the two half-assemblies will advantageously be glued, the adhesive used for the junction plane being chosen with a transmission coefficient greater than 90%, for a pressure exerted according to the layers of fibers of approximately 1 to 1, 8 millibar, and flexible to withstand the possible tensions resulting from the differences in expansion of the successive materials considered according to the height of this junction plane; such an adhesive will, for example, be a polymerizable resin with a refractive index close to that of the core of the fibers. The two half-assemblies brought back end to end, will be correctly repositioned by means of two guide cylinders, here not shown, inserted respectively in the lateral grooves in v-shaped shapes 21 and 22, each also cut but the two remaining parts of which are brought back together then clamped against each other according to the layers of fibers. This produces a fixed connection between fibers belonging to two initial plies.

En variante, lorsqu'on veut réaliser une jonction démontable les faces des deux demi-ensembles ne seront pas encollées, les deux demi-ensembles ramenés bout à bout et repositionnés à l'aide de cylindres de guidage dans les rainures latérales seront simplement maintenus bloqués avec pression l'un contre l'autre, avec interposition éventuelle d'un liquide ou d'un composé semi-liquide d'indice de réfraction voisin de celui du coeur des fibres entre les faces du plan de jonction.  As a variant, when it is desired to make a removable junction, the faces of the two half-assemblies will not be glued, the two half-assemblies brought back end to end and repositioned with the aid of guide cylinders in the lateral grooves will simply be kept blocked. with pressure against each other, with possible interposition of a liquid or a semi-liquid compound with a refractive index close to that of the core of the fibers between the faces of the junction plane.
