Title
(EN) FUSION SPLICING BLOCK
(FR) BLOC D'EPISSURE PAR FUSION
Abstract
(EN)
A consumable fusion block for fusing optical fibers includes non-conducting substrate with at least one flat surface. A pair of electrodes overlay the flat surface of the substrate and are spaced apart on either side of a passline such that each electrode tip end is adjacent the passline. A space between the electrode tips defines an arc region which can be covered to form a semi-enclosed arc region. A method is also provided for manufacturing a plurality of fusion blocks from a single slab of non-conducting material by overlying the non-conducting material with a length of conducting material, bonding the conducting material to the non-conducting material, and cutting the slab into smaller fusion blocks.
(FR)
Un bloc consommable d'épissure par fusion, pour réunir par fusion des fibres optiques, comprend un substrat non conducteur doté d'au moins une surface plane. Une paire d'électrodes recouvrent la surface plane dudit substrat et sont placées à distance l'une de l'autre, de chaque côté d'une ligne de raccordement de sorte que chaque extrémité d'électrode soit adjacente à cette ligne. Un espace ménagé entre les extrémités des électrodes définit une région en arc qui peut être couverte pour former une région en arc à demi enfermée. Un procédé de fabrication d'une pluralité de blocs d'épissure par fusion à partir d'une plaque unique d'un matériau non conducteur est également décrit, ce procédé consistant à recouvrir ledit matériau d'une longueur d'un matériau conducteur, à les coller ensemble et à découper la plaque en blocs d'épissure de taille inférieure.
