SPLIT TYPE COATED OPTICAL FIBER TAPE

摘要

PROBLEM TO BE SOLVED: To provide a split type coated optical fiber tape with which the terminal processing work to split and divide the tape into plural subunits is made easy, and to easily and rapidly lay or wire the wires. SOLUTION: Coated optical fiber tapes 8 each produced by arranging plural optical fibers 1 in parallel and applying an integrating coating layer of an UV-curing resin are arranged in parallel in the width direction and coated and connected with a connecting resin coating layer 1b comprising a UV-curing resin to obtain the coated fiber tape of the purpose. The yield stress of the connecting resin coating layer 1b ranges from 0.30 kg/mm2 to 1.0 kg/mm2, and the fracture elongation of the layer 1b is 20 to 80%. The yield stress of the integrating resin layer 1a is controlled to be larger than the yield stress of the connecting resin coating layer 1b.
