Abstract: An optical fiber device 10 characterized in comprising a support mechanism 11 that supports an optical fiber connector 1 having components 2 with a two piece structure disposed one over the other and held against each other by a tension means, and at one end or the other end of which one or the other optical fibers 3,3 is inserted between said components, determining the alignment position so as to be able to connect optical fibers end to end, a separation member 20 releasing said optical fibers by spreading in the direction of separation of said components by opposing the tension of said tension means when inserted into said components from a direction straight along the longitudinal direction of said optical connector, and a push pressure device 30 which inserts said separation member between said components by applying pushing pressure in the direction of the optical connector to said seperator, and while applying end to end force to both optical fibers end to end in the component, closes the component, an

Abstract: An optical fiber connector comprising a base and a lid member constituting an element having a doubly split structure which forms a roughly rod-like shape when united, and a spring for housing the base and lid member and applying pressure for pressing them together, wherein centering grooves for positioning and centering optical fibers for adjoinment and connection are provided in at least one or between the opposing faces of the base and lid member which are put together. In a mode wherein the element is inserted into a C-shaped spring having a rod shape with a C-shaped cross section, the optical fibers which are inserted from both ends of the element are pushed to the centering groove and adjoined into connection. By inserting or withdrawing wedges into wedge insertion grooves formed between the base and the lid member, it is possible to open or close the element.
