Optical fiber array having fiber islands in a polymer sea

摘要

An optical fiber array comprising a great number of multifilament type plastic optical fibers having a substantially rectangular peripheral sectional shape and including 10 to 10000 light- transmitting islands having a diameter of 5 to 200 m, which are densely arranged in the sea, wherein one ends of the multifilament type plastic optical fibers are arranged in one line or a plurality of lines and the other ends thereof are integrated in a substantially rectangular or substantially circular shape.
