摘要： In order to avoid a frequent multiple crossing in an optical fiber in a sheet and attach the optical connector near a marginal end of the sheet while maintaining a sufficient extra length and more extra length for attaching the optical fibers, in the optical fiber sheet 6, an optical fiber 5 as an extra length section in the optical fiber path is disposed on three-layer wiring planes which are formed by attaching four sheets 1, 2, 3, and 4. Notched sections 2a and 3a are formed in the intermediate layers 2 and 3. The optical fiber 5 communicates from a first wiring layer to a second wiring layer via the notched section 2a so as to communicate from the second wiring layer to a third wiring layer via the notched section 3a.

摘要： 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.

摘要： An optical connector ferrule has an optical fiber containing hole reaching from the rear end surface near the end surface and a fine pore extending from the optical fiber accommodating hole to the end surface to be connected. A bare fiber of a polarization-maintaining optical fiber is inserted into the fine pore. Since the length of the fine pore is short, the influence of the uniformness of the adhesive in the fine pore is smaller, and therefore the stress distribution is maintained, resulting in stabilizing the polarization characteristics. A flange unit is attached to the ferrule after an optical fiber is inserted to the ferrule and fixed. Therefore the optical fiber is easily adjusted with respect to the housing in the circumferential direction around the axis, and optical fibers are connected by but joining with high accuracy.
