Watch the fiber display for bubbles, fiber offset, or arc stability issues that could signify a defective splice. Slide a matching heat shrink protection sleeve over the splice point. This bubble causes extreme fiber optics splicing high loss as shown visually via Visual Fault Locator (VFL) on the right hand side image. Proper care should. Are you splicing multi-mode fiber? If not put it on splicing mode auto Fusing power calibration should only be done with SM fiber, even if you're splicing MM. If you use MM for the calibration it'll throw off the arc power. These splicers are a nightmare for throwing this error up ! As the previous. 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.
