I hope this message finds you well. I have read your work, "Inscription and Optimization of Fibre-Optic Long Period Gratings Using Electric Arc Discharge," with great interest. I noticed that you utilized the Fujikura 60S splicer to generate periodic electric arcs along the entire fiber to modify the refractive index periodically and inscribe Bragg gratings.

I am currently attempting a similar approach, but I am using the Fujikura 90S+ splicer. I would be immensely grateful if you could provide some guidance regarding the specific steps you employed in the Fujikura 60S menu to disable the splicing mode and configure the device to generate arcs periodically with varying power and duration.

In particular, my PhD student and I are facing a challenge: when we place the entire fiber between the electrodes and attempt to set it, we encounter an error message stating, "Fiber too long." Could you kindly explain how you managed to configure your splicer to bypass this issue and successfully generate arcs along the full length of the fiber without triggering similar errors?

I deeply appreciate your expertise and your spirit of collaboration.
