Abstract
The splicer comprises a stationary block provided with a first V shaped groove for accommodating opposing ends of optical fibers, and an opening perpendicular to the groove. On the opposite sides of the stationary block there are provided a pair of slidable blocks provided with second grooves in alignment with the first groove and clamping means for clamping the fibers. The slidable blocks are moved toward and away from the stationary block by micrometers. A heater is provided in the opening for heating and fusing together the opposing ends of the optical fibers.
