<p>A multi-stage fiber processing system comprises first (20) and second (22) fiber holders configured to hold respective portions of at least one fiber (10) and a plurality of heat sources (HS1, HS2 ) arranged between the first and second fiber holders and configured to provide a heat zone (50) that axially extends about the at least on fiber. The first and second fiber holders can be configured to translate away from each other for tapering. The plurality of heat sources can include two 3 electrode heat sources that deliver an extended, substantially isothermic heat field axially about the fiber. All but one heat source can be turned off to splice the fiber. The two 3 electrode heat sources can generate 9 arcs to from the heat zone, wherein arcs between the two 3 electrode heat sources can be rotated about the at least one fiber.</p> |
