Abstract
Systems and techniques are described for improving reproducibility in a pre-splice heat treatment. A heat treatment station is described for applying a pre-splice beat treatment to a lead end of a first optical fiber having a first modefield diameter. The heat treatment station comprises a base, and a fiber clamp for holding the first optical fiber such that a length of the lead end of the first optical fiber is positioned over a heat source mounted to the base. The heat source causes a controlled expansion of the first fiber modefield at the first fiber lead end to form an internal bridge. The heat treatment station further includes position adjustment means for adjusting the length of the first fiber lead end that is exposed to the heat source.
