Inaccurate fibre alignment can lead to high splice loss and unreliable connections. 1 dB). However, even the most advanced fibre fusion splicer is prone to occasional problems due to environmental conditions, mechanical wear, or user error. Understanding these issues and how to solve them is essential for ensuring uninterrupted fibre optic network performance. The fusion arc burns over 5,000°C and can cause serious burns in an instant. When stripping and cleaving fiber, fine glass shards can be released that, if not properly cleaned up and disposed of, can lodge in the. When fusion splicing in the field, a number of issues can arise, causing equipment errors and faulty splices, leading to high splice loss.
