The Type-66 TuffCat mass fusion splicer features the industry's first Dual-Automatic-Splice Protection Sleeve Heater System - Sumitomo's exclusive patent-pending system. The dual heater system's simultaneous operation helps to eliminate squandered time waiting for a single heater system to complete its cycle. Instead, the streamlined splicing process reduces the bottle neck of "heater wait time" by 88%, improving mass splicing effciency and productivity in the fiel by 70%.

The TuffCat features an effortless fiber holder systme to increase splice repeatability while making the unit easy to use regardless of the operator's experience level Utilizing precision v-groove alignment, the TuffCat can be used for all types of ribbon and single splicing with an optimum arrangement for ease of use in trunk, aerial, or taut-sheath applications.

The TuffCat mass fusion splicer embodies Sumitomo's mission of customer focused engineering by reducing the customer's overal cost of ownership. The unit features electrodes common with both the Type-39 FastCat and the Type-25e TomCat handheld splicers, as well as existing Sumitomo Type-61, 62, 63, and 65 fusion splicers.
