Abstract

The cable has a set of connectors, a set of ends, and a plastic sheath (1) for providing protection to the set of connectors during transport and pulling of the cable. A transition case (4) is utilized for coiling and storage of surplus length of the cable that is utilized for wiring in a building e.g. multi-storey dwelling. The set of connectors is shifted with regard to each other for allowing insertion of the set of connectors in the plastic sheath. The connectors are mounted on the cable in an optical connection node (7).

Description

La présente invention concerne l'utilisation des câbles fibre optique dont les connecteurs optiques sont montés sur les câbles et testés en usine avant leur livraison. L'application de cette invention est destinée pour le câblage fibre optique très haut débit dans les logements collectifs et individuels. The present invention relates to the use of optical fiber cables whose optical connectors are mounted on the cables and tested at the factory before delivery. The application of this invention is intended for very high speed optical fiber cabling in collective and individual dwellings.

La technique de câblage fibre optique employée traditionnellement impose le raccordement des connecteurs après la pose du câble. Ceci requiert l'intervention dans les logements d'un technicien hautement qualifié ainsi que des appareillages de raccordement de connecteurs coûteux. La présente invention est caractérisée en ce qui concerne l'utilisation des câbles fibre optique pré connectés et pré testés en usine ainsi que le test à distance après leur pose. Ce test est effectué à l'aide d'un bouclage de deux brins du câble dans le logement. Cette invention supprime l'intervention des techniciens fibre optique dans les logements. Les câbles peuvent être posés et raccordés ensemble par un électricien non qualifié en fibre optique. Ce procédé permet donc une forte diminution du coût et du temps passé dans les logements. L'invention peut être mise en application pour le câblage fibre optique des trois catégories de logements : Logements collectifs, grand immeuble Logements collectifs, petit immeuble Logements individuels LOGEMENT COLLECTIF D'UN GRAND IMMEUBLE Fig.! Le câblage optique d'un logement collectif d'un grand immeuble consiste en un câble horizontal de 2 ou 4 brins pré connecté les deux cotés (1) et un câble vertical multi brins également connecté les deux cotés (2). Le câble horizontal est branché à une extremité sur une prise optique située dans le logement (3) et à l'autre extrémité sur un boîtier de transition (4) situé dans la gaine technique du bâtiment. Le câble vertical est branché à une extrémité sur le boîtier de transition et à l'autre extrémité sur un boîtier de mutualisation (5) situé au pied de l'immeuble. Le test après pose est effectué dans le boîtier de mutualisation (6) après avoir constitué une boucle sur deux brins du câble dans la prisé optique du logement (7) ceci permettant l'aller-retour du signal de test à distance. LOGEMENT COLLECTIF D'UN PETIT IMMEUBLE Fig.2 Le câblage optique d'un logement collectif d'un petit immeuble consiste en un câble de 2 ou 4 brins pré connecté les deux cotés (1). Le câble est branché à une extremité sur la prise optique dans le logement (2). Il est ensuite passé au travers d'un boîtier de dérivation (3) (voir page 2, ligne 16). L'autre extrémité est branché sur le boîtier de mutualisation (4) situé au pied de l'immeuble. Le test après pose est effectué dans le boîtier de mutualisation (5) après avoir constitué une boucle sur deux brins du câble dans la prise optique du logement (6) ceci permettant l'aller-retour du signal de test à distance. LOGEMENT INDIVIDUEL Fig. 3 Le câblage optique d'un logement individuel consiste en un câble de 2 ou 4 brins pré connecté les deux cotés de type intérieur (1) et un câble de 2 ou 4 brins de type extérieur pré connecté de coté logement uniquement. Le câble extérieur peut être de type souterrain (2) ou aérien (3). Le câble intérieur est branché à une extremité sur la prisé optique (4) situé dans le logement et l'autre extrémité sur un boîtier de transition (5) situé à extérieur du logement Le câble extérieur est branché à une extrémité sur le boîtier de transition et l'autre extrémité est installé dans le noeud de raccordement optique (6) situé à proximité du logement. Les connecteurs - 2- sont ensuite montée sur le câble dans le noeud de raccordement optique (7 ). Le test après pose est effectué dans le noeud de raccordement optique après avoir constitué une boucle sur deux brins du câbles dans la prisé optique du logement (8) ceci permettant l'aller-retour du signal de test à distance. The fiber optic cabling technique traditionally used requires the connection of the connectors after laying the cable. This requires intervention in the housing of a highly qualified technician as well as expensive connector connection equipment. The present invention is characterized with regard to the use of pre-connected and pre-tested fiber optic cables at the factory as well as the remote test after their installation. This test is performed using a loop of two strands of the cable in the housing. This invention removes the intervention of fiber optic technicians in homes. The cables can be laid and connected together by a non-fiber optic electrician. This process therefore allows a significant reduction in the cost and time spent in housing. The invention can be implemented for fiber optic cabling of the three categories of housing: Collective housing, large building Collective housing, small building Individual housing COLLECTIVE HOUSING OF A LARGE BUILDING Fig.! The optical wiring of a collective housing of a large building consists of a horizontal cable of 2 or 4 strands pre-connected on both sides (1) and a multi-strand vertical cable also connected on both sides (2). The horizontal cable is connected at one end to an optical socket located in the housing (3) and at the other end to a transition housing (4) located in the building's technical duct. The vertical cable is connected at one end to the transition box and at the other end to a pool box (5) located at the foot of the building. The post-installation test is performed in the pooling box (6) after forming a loop on two strands of the cable in the optical slot of the housing (7) allowing the round trip of the remote test signal. COLLECTIVE HOUSING OF A SMALL BUILDING Fig.2 The optical wiring of a collective dwelling of a small building consists of a cable of 2 or 4 strands pre-connected on both sides (1). The cable is connected at one end to the optical socket in the housing (2). It is then passed through a junction box (3) (see page 2, line 16). The other end is connected to the pool box (4) located at the foot of the building. The post-installation test is carried out in the pooling box (5) after having constituted a loop on two strands of the cable in the optical socket of the housing (6) this allowing the round-trip of the remote test signal. INDIVIDUAL HOUSING Fig. 3 The optical wiring of an individual housing consists of a cable of 2 or 4 strands pre-connected on both sides of the indoor type (1) and a cable of 2 or 4 strands of outdoor type pre-connected on the housing side only. The outer cable may be of the underground (2) or overhead (3) type. The inner cable is connected at one end to the optical socket (4) located in the housing and the other end to a transition box (5) located outside the housing. The outer cable is connected at one end to the transition housing. and the other end is installed in the optical connection node (6) located near the housing. The connectors - 2- are then mounted on the cable in the optical connection node (7). The test after installation is performed in the optical connection node after having constituted a loop on two strands of the cable in the optical slot of the housing (8) allowing the round trip of the remote test signal.

PROTECTION DES CONNECTEURS Fig. 4 Les connecteurs optiques pré connectés sont fragiles. Pour les protéger pendant le transport et le tirage du câble, les connecteurs sont insérés dans une gaine thermo rétractable (1). Les connecteurs sont montés sur le câble de manière décalé (2) permettant ainsi leur insertion dans une gaine thermo rétractable de 12mm. CONNECTOR PROTECTION Fig. 4 Pre-connected optical connectors are fragile. To protect them during transport and pulling the cable, the connectors are inserted into a heat-shrinkable sleeve (1). The connectors are mounted on the cable in a staggered manner (2) thus allowing their insertion into a 12mm heat-shrinkable sheath.

STOCKAGE DE LA LONGUEUR DU CABLE EXCEDENTAIRE L'installateur se dispose sur le lieu de câblage, des câbles pré connectés des longueurs allant de 10m à 40m et ceci par pas de 2m. L'installateur mesure la longueur de parcours du câble à poser. Il installe un câble d'une longueur correspondant à cette mesure en gardant une marge de sécurité de 50cm minimum. Après la pose, la longueur de câble excédentaire est lovée et stockée dans un boîtier de transition dans le cas des grands logements collectifs, Fig.1(4) et des logements individuels, Fig. 3(5). Dans le cas des petits immeubles collectifs, elle est lovée et stockée dans un boîtier de dérivation électrique situé au pied de l'immeuble en amont du boîtier de mutualisation, Fig. 2(3). STORING THE LENGTH OF THE EXCEDENT CABLE The installer has available at the place of wiring, cables pre-connected lengths ranging from 10m to 40m in steps of 2m. The installer measures the length of the cable to be laid. It installs a cable of a length corresponding to this measurement while keeping a margin of safety of 50cm minimum. After laying, the excess cable length is coiled and stored in a transition housing in the case of large collective dwellings, Fig.1 (4) and individual dwellings, Fig. 3 (5). In the case of small apartment buildings, it is coiled and stored in an electrical junction box located at the foot of the building upstream of the pooling box, Fig. 2 (3).
