<p>The present invention is directed to an optical fiber connector for fiber lasers having improved signal conduction which minimizes optical losses. This optical fiber connector is capable of operating at high power levels, by dissipating heat and by maintaining the alignment of the optical fibers even when the fibers thermally expand in the presence of high temperature. The connector may be made of a shape memory alloy having a generally cylindrical body and a longitudinal conduit for splicing together the optical fibers.</p>
