摘要：

An　efficient　and　mechanically　robust　fusion　splicing　method　for　the　splice　of　special　soft　glass　fiber　to　standard　silica　fiber　has　been　demonstrated.　An　asymmetric　temperature　gradient　fusion　splicing　method　created　a　temperature　gradient　between　the　special　soft　glass　fiber　and　the　silica　fiber　by　heat　conduction,　hence　met　the　fusion　temperature　requirement　of　the　two　fibers　with　different　softening　temperatures.　Adding　the　preheating　process　avoided　the　over-softening　at　splicing　interface　of　soft　glass　fibers　and　help　to　reduce　the　splicing　losses　causing　by　core　offset　and　bending.　In　this　paper,　by　adjusting　parameters　such　as　fusion　splicing　power,　offset　distance,　preheating　time　and　heating　time,　the　minimum　splicing　loss　of　0.49　dB　between　a　12/220　μm　fluorotellurite　fiber　and　an　8.2/125　μm　silica　fiber　(SMF-28e)　was　achieved　experimentally.　©　2019　IEEE.
