Abstract
A method and apparatus for connecting optical fibers using a grooved steel wire to position a pair of guide sleeves and a fitting sleeve into which a pair of optical fibers may be inserted so that end portions thereof bear against each other. A thermal melting adhesive sleeve and a thermal shrinking tube are provided to cover the steel wire, the guide sleeves and the fitting sleeve so that when the thermal melting adhesive sleeve and the thermal shrinking tube are heated, the thermal shrinking tube is shrinked while the adhesive sleeve is melted to integrate the steel wire, the fitting sleeve, the guide sleeves and the optical fibers with each other.
