摘要： An apparatus for fushion splicing optical fiber with three pairs at clamps; the outermost pair of clamps has one rotatable clamp mechanism that is manually operated and a second rotatable clamp mechanism that is operated by a motor. A rapid fine adjustment of the alignment of the polarization maintaining optical fibers can be made.
