Type-39 Datasheet
The Sumitomo Type-39 FastCat Core Alignment Fusion Splicer is the industry’s first splicer to feature a Dual-Automatic Heater System featuring Auto Start Heater and Auto Start Splice functions — making the FastCat the fastest splicer available today. The Type-39 FastCat’s advanced electronic design, which accommodates the built-in dual heating system and simultaneous operation, reduces the bottle neck of “heater wait time” by 88%. With an individual heater cycle time of only 30 seconds (60mm Fiber Protection Sleeves) and a splice cycle of only 9 seconds, the FastCat improves splicing efficiency by 70%.
