5.2.7. Main Toolbar
The illustrated buttons on the toolbar right above the image window execute processes critical to splicing and data
management.
Open:
opens a splice data file. This means it loads an XML file containing predefined parameters in
preparation for a splice or a taper. Splicing systems are come preinstalled with basic files (such as a
SMF-28 to SMF-28 splice). Those are available under specific filament folders. Be sure to have the
corresponding filament installed before using a file.
Save:
saves the parameters currently in use to an XML file that can be accessed later. In the case
you are using an XML file given by Vytran, it is recommend that you perform a “Save As” so that the
standard file can be referenced in the future.
Purge :
increases the argon flow throughout the unit, removing air and impurities that may
contaminate the splice process. You should perform this at least once every time you turn on the
argon supply.
Load fibers
: This moves the fibers to the splice position, using predetermined fiber loading
positions for the fiber holding blocks. You can change these positions by right-clicking on the “load
fibers” button.
Gap:
This button gaps the fibers, moving the fibers so that the end faces are at the Pre-Gap distance
specified under Splice Parameters.
Alignment:
This function will find the edges of the fibers and aligned them. This will only align the
fibers in the current view (front or back). So it is necessary to repeat this process in a perpendicular
view. The Alignment Process will not work if both edges of each fiber are not on the screen. In the end
view, this process will rotate the fiber and align it based on the current PM Alignment Settings.
Core alignment:
This button aligns the cores of the fibers, bringing the cores into alignment, rather
than aligning the fibers using their edges.
Active alignment
: This button aligns the fibers actively using an (external) light source and power
meter. The power meter must be connected to one of the “Analog” ports on the back panel. The
analog input reading can be configured under Configuration Analog Input Configuration with the
Channel set to the appropriate port.
Splice only :
This button executes the basic splice process, meaning it sends the lens home (if it
has not been done), brings the splice head into position, and executes a splice according the splice
parameters. This process will not attempt to align the fibers; it is useful in the case where the fibers
have been manually aligned.
Loss estimation :
This button estimates the loss in a splice, based on the appearance of the cores
in the splice region. For more accurate estimation, you need to have the correct calibration file. Please
contact Vytran for more assistance.
Load Taper :
This button moves the fiber holding blocks into the predetermined locations for a
particular Taper Process and automatically performs an antibacklash process.
Taper:
This will execute the taper process. See section 5.7 for further information regarding tapering.
One Button Process:
This executes the Splice Routine found under Splice Splice Process
Editor, which generally includes alignment and gapping. The blue button labeled “START” on the front
right corner of the GPX has the same function.
