Abstract
An array splice for ribbon-like multi-core optical fibers comprises capillary tubes of ultraviolet-transmitting glass each having an inner diameter slightly larger than the outer diameter of the clad of an optical fiber, each glass capillary tube including tapered portions on the opposite ends thereof for insertion of optical fiber bodies, and a groove formed in the middle upper surface region thereof for discharging bubbles and adhesive agent, and a base including recesses formed in the middle upper surface region thereof for receiving and supporting the lower portions of the tube walls of the glass capillary tubes, and a plurality of front-edged separators each disposed at the opposite ends of the associated receiving and supporting recess. The separators are disposed with approximately the same pitch as that for the capillary tubes. Defined between adjacent separators are optical fiber insertion paths having a width which increases with increasing distances from the opposite ends of each capillary tube.
