Multi Trace Analysis
 
For Evaluation of Multicore Fiber
Up to four traces can be overlaid on the display for analysis and comparison.

This is useful for evaluating connection point locations and loss after installing multicore fiber.
2 Way Trace Analysis
 
For Accurate Splice Loss Measurement by Bi-directional Testing
Merges the two traces measured from both directions and finds the correct splice loss.

Connection point loss in lines where optical fibers of differing backscatter coefficients are connected can differ depending on the direction. In such cases, you can accurately determine the loss by measuring in both directions and taking an average.
Differential Trace Analysis
 
For Evaluation of Aged Deterioration
Displays the difference between two specified traces.

Makes it simple to check aged deterioration of fibers or connection points, or fluctuation in loss between fibers, and other phenomena.
Section Analysis
 
For Evaluation of Total Return Loss
Finds the total return loss in specific portions of the fiber.

This type of evaluation is often requested because the multiple reflections from optical fiber networks can affect signal light from transmitters (cable TV etc.).
