When it comes to high-volume fiber splicing, you want to be able to operate quickly.  The following are some of the current lineup of the fastest fusion splicers on the market and their associated splicing speeds:

Techwin TCW-605:
Fiber Splicing Speed: 8 Seconds
Sleeve Heating Speed: 30 Seconds
Total Splice Time: 38 seconds

 Fujikura FSM-60S:
Fiber Splicing Speed: 9 Seconds
Sleeve Heating Speed: 30 Seconds
Total Splice Time: 39 seconds

Sumitomo Type-39:
Fiber Splicing Speed: 9 Seconds
Sleeve Heating Speed: 30 Seconds
Total Splice Time: 39 seconds

Fujikura FSM-50S:
