ETK 1524099 Confidential Excellent Performance Accurate Loss Estimate Comparison Thanks to its ability to process the core image, the Sumitomo T-55 beats the cladding aligners on loss estimate accuracy. The better performance, the nearer to pink line on the graph. SUMITOMO T-55 Fujikura FSM-21 S INNO VIEW 3 22/23 Poor loss estimate accuracy causes more splicing reworks and increases operational costs.
