Why are there air bubbles in fiber optic cable splices

There are bubbles or cracks in the joints during welding This situation may be due to poor cutting of the optical fiber, such as inclined end faces, burrs, or unclean end faces. It is necessary to clean the optical fibers before performing fusion splicing operations; another case is that the. Most splice failures happen for simple reasons—and they're completely avoidable. Poor Cleaving – The #1 Cause of Bad Splices A perfect splice starts with a. Image of a bubble at the fusion splice between two ordinary multimode fiber optics. This bubble resulted from dirt on the fiber end surface. Whether it's from misalignment, dust contamination, environmental stress, or poor splice protection, these problems can quickly escalate if not. 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 posters said give it a good clean. Fiber optic pigtails are used to connect fiber optic cables using fusion or mechanical splicing.
