  • What to do if the fiber splicing machine fails to connect the pigtail

    What to do if the fiber splicing machine fails to connect the pigtail

    Inaccurate fibre alignment can lead to high splice loss and unreliable connections. If an error code appears, consult the user manual's troubleshooting section. Fibre fusion splicers are critical instruments in modern optical fibre installation and maintenance. When properly maintained and operated, they produce low-loss, high-strength splices. To counteract these errors, technicians can go through the following troubleshooting checklists: Perform an Arc Test: Before splicing, it's important to perform. While the Sangken Splicing machines are designed for high-precision work, even the best equipment requires proper troubleshooting when splices fall outside of spec. Here. However, if the splices and slack are placed into the splice tray without properly following the tray's cable guides, it could result in exceeding the bend radius of the fiber. To locate this type of stress, you may need to test at two wavelengths – 850 and 1300nm for multimode and 1310 and 1550.
