After fine tuning the alignment and before fusion the alignment should be as follows the outer edges of the fibers line up and the gap between their end faces is centered on the monitor and as small as possible while still allowing for up and down movement of the fibers QO Fuse When the fibers are aligned to your satisfaction you can press the FUSE button and start fusion The splicer will follow the splicing program you chose earlier in our case program 03 As the FSU 995 FA splices your fibers it will read Splicing in the message field Check the splice Once the splicing sequence is complete you need to check the splice The steps for this procedure are outlined in the following section 20 BASIC OPERATION Manual mode splicing ll Outer edges lined up Gap c ntered and as narrow as possible Fuse fibers SPLICING 4i Splice evaluation Loss estimation After the splicing sequence is complete the splicer estimates dd FSU 995 FA AUTO MODE the splice loss and displays it in the mode field CHECKING SPLICE dd ESTIM LOSS x xx dB NEXT PICTURE VIEW yy 2 Re fuse Optional step This option is not available if you are using the hot core or the df ESTIM LOSS x xx dB Small core alignment process Program 05 in the case of the FOR REFUSING pre defined programs PRESS FUSE BUTTON py With all other splicing processes if you judge that the splice loss is2.
